INTRODUCTION

INTRODUCTION

The Rhode Island Turnpike and Bridge Authority (RITBA) currently owns/controls, operates and maintains the Newport Pell, Mount Hope, Jamestown Verrazzano and Sakonnet River Bridges as well as ten other minor bridges. Additionally, RITBA owns/controls, operates and maintains Rhode Island Route (RI) 138 from Route 1A in North Kingstown to the Newport Pell Bridge in Jamestown, the Jamestown toll plaza and various facilities.

History

The Rhode Island Turnpike and Bridge Authority was established in 1954 by the Rhode Island General Assembly as a corporate and politic body with the power to acquire, construct, maintain and operate bridge projects. According to Section 3 of Rhode Island Public Law Chapter 3390, the Authority was created to facilitate vehicular traffic, remove many of the present handicaps and hazards on the congested highways in the state, alleviate the barriers caused by large bodies of water, and promote the agricultural and industrial development of the state.

In 1963, Public Law Chapter 165 amended Title 24, Chapter 12 to dissolve the Jamestown Bridge Commission and Mount Hope Bridge Authority. Under this amendment, ownership of the original Jamestown Bridge (1940-1992) between North Kingstown and Jamestown was transferred to the State of Rhode Island and ownership of the Mount Hope Bridge between Portsmouth and Bristol was transferred to RITBA. The Rhode Island Turnpike and Bridge Authority was responsible for the construction of the Newport Bridge (renamed the Claiborne Pell Bridge in 1992 and commonly referred to as the Newport Pell Bridge) between Jamestown and Newport, which opened to traffic on June 28, 1969.

In 2013, the Rhode Island General Assembly amended Title 24, Chapter 12 to allow RITBA to take control of the Sakonnet River Bridge and the Jamestown Verrazzano Bridge from the State of Rhode Island. Along with the Sakonnet River Bridge, two adjacent minor bridges, a maintenance facility, a bike path, storm drainage systems, roadway lighting and other related components were transferred to RITBA’s jurisdiction. Portions of RI 138 from the west abutment of the Jamestown Verrazzano Bridge to the Route 1A interchange in

2020 TEN YEAR RENEWAL AND REPLACEMENT PLAN - NARRATIVE SUMMARY PAGE 1 OF 59 INTRODUCTION

North Kingstown and from the east abutment of the Jamestown Verrazzano Bridge to the Jamestown toll plaza were also transferred to RITBA. This combined 2.7 mile long segment of RI 138, referred to herein as the RI 138 Connector Highway, includes seven minor bridges, a stormwater pump station, roadway lighting, landscaping and an extensive storm drainage system.

The 2014 Rhode Island General Assembly passed Article 21 of the Fiscal Year (FY) 2015 Appropriations Act. Under this Act, 3.5-cents of the gasoline tax was allocated to RITBA starting in FY 2015 for use on maintenance, operations, capital expenditures and debt service. This allocation is in lieu of tolling the Sakonnet River Bridge, which was originally authorized by the 2012 Rhode Island General Assembly and reconsidered after public debate over the tolling.

Authority Composition

RITBA is overseen by a Board of Directors and has no stockholders or equity holders. The Board of Directors consists of five members including four members appointed by the Governor on four-year terms as well as the Director of the Rhode Island Department of Transportation (RIDOT) who is a member ex-officio. The Board of Directors elect a chairman and vice-chairman amongst their ranks. RITBA’s Chief Financial Officer (CFO) serves as treasurer and RITBA’s Executive Director serves as secretary.

Ten-Year Renewal and Replacement Plan

RITBA has historically developed a Ten-Year Renewal and Replacement plan (10-Year Plan) for their long-term physical assets – bridges, roadways and facilities. The 10-Year Plan is updated annually and includes the planned capital improvements with associated estimates of construction, engineering, maintenance and inspection costs. The items identified in the 10-Year Plan for the bridges are based on existing conditions documented in the latest inspection reports as well as discussions with RITBA staff and engineering consultant firms under contract with RITBA. All bridges were inspected by an engineering consultant firm in accordance with Federal Highway Administration’s (FHWA) National Bridge Inspection Standards (NBIS), which mandates a routine biennial inspection. In addition to the routine biennial inspections, RITBA sanctions supplemental inspections on a case-by-case basis based on existing conditions or structure complexity. Bridge inspections entail the visual inspection of the entire structure, as well as a hands-on inspection of all Fracture Critical Members (tension members whose failure would result in partial or total collapse of a span or structure).

2020 TEN YEAR RENEWAL AND REPLACEMENT PLAN - NARRATIVE SUMMARY PAGE 3 OF 59 INTRODUCTION

Summary of Planned Work

The 10-Year Plan includes a total investment over the next 10 years of approximately $230 million. Item lists are provided in the Appendix in which this investment is organized into seven major categories. The investments for each category are as follows:

Newport Pell Bridge: $122M Mount Hope Bridge: $ 48M Jamestown Verrazzano Bridge: $ 32M Facilities: $ 10M Sakonnet River Bridge: $ 8M Minor Bridges: $ 5M RI 138 Connector Highway: $ 5M

As shown above and in the adjacent chart, work at the two structurally significant suspension bridges comprise the majority of the planned investments included in the 10- Year Plan. Approximately 74% of the anticipated expenditures are for the Newport Pell and Mount Hope Bridges, which is expected given the complexity, size and age of these structures.

The Jamestown Verrazzano Bridge represents 14% of the anticipated cost in this ten-year period, which is reasonable since it’s the second longest bridge in RITBA’s inventory. The Sakonnet River Bridge, minor bridges, RI 138 Connector Highway and the various facilities comprise approximately 12% of the total cost of anticipated work.

2020 TEN YEAR RENEWAL AND REPLACEMENT PLAN - NARRATIVE SUMMARY PAGE 4 OF 59 NEWPORT PELL BRIDGE

NEWPORT PELL BRIDGE

The Newport Pell Bridge opened to traffic on June 28, 1969 and carries RI 138 over the East Passage of Narragansett Bay between the town of Jamestown on Conanicut Island and city of Newport on Aquidneck Island. The bridge also spans over Bay View Drive in Jamestown. This 55-span bridge has a total structure length of 11,248 feet, which includes 3 steel suspension spans, 11 steel deck truss approach spans, 18 steel floor system (girder-floorbeam-stringer) approach spans, 3 multi steel beam approach spans and 20 multi AASHTO Type IV prestressed concrete girder approach spans. The main suspension span is 1,600 feet long and the two side suspension spans are 687 feet each, making it the longest suspension span bridge in New England and 87th in the world. The steel towers extend over 400 feet above the water.

Structures included:

Newport Pell Bridge Steel suspension bridge for 3 spans, steel deck truss for 11 spans, steel floor system for 18 spans, multi steel beam for 3 spans and multi AASHTO Type IV prestressed concrete girder for 20 spans (11,248 feet total length)

As shown in the above chart, bridge deck repair and maintenance account for roughly 41% of the anticipated expenditures over this ten-year period. The extensive repairs are needed because of the age of the deck, which is from the original construction of the bridge.

Approximately 16% of anticipated costs are for the suspension main cable unwrapping, repair and dehumidification, which aid in the preservation of the structural integrity of the wire strands. The main cables serve as the primary structural load path in the suspended spans and are amongst the most vital components on the bridge.

2020 TEN YEAR RENEWAL AND REPLACEMENT PLAN - NARRATIVE SUMMARY PAGE 5 OF 59 NEWPORT PELL BRIDGE

Item 1: Future Repairs/Minor Rehabilitation On-Call Contract

This item reflects an on-going, smaller scale repair program to address items identified during bridge inspections that should not wait until a larger repair program can be initiated. This item also includes smaller scale studies and testing programs which provides information to RITBA for use when developing and prioritizing larger repair/rehabilitation programs.

Examples of repairs, as recommended in the 2017 (approach spans) and 2018 (main spans) Biennial Inspection Reports, which could be performed under this item include:

• Perform a detailed assessment of each of the suspender rope socket stiffeners at each panel point in order to track deterioration and develop a prioritization order for future replacement. • Repair all truss members and bracing members that exhibit significant section loss, areas of cracking, through holes, or severely corroded fasteners within the east and west deck truss spans as required to provide full design load carrying capacity. • Repair all floorbeam and stringer webs, flanges, stiffeners, and connection plates, and other floor system elements that exhibit cracks, through holes, or significant section loss within the west approach spans as required to provide full design load carrying capacity. An analysis should be performed to determine the threshold for which repairs are warranted in the areas of section loss found throughout the floor system.

Item 2: Miscellaneous Maintenance and Repairs

This item includes maintenance projects that are not covered in the specific items below. These projects are beyond the scope of routine maintenance tasks. Examples of repairs, as recommended in the 2017 (approach spans) and 2018 (main spans) Biennial Inspection Reports, which could be performed under this item include:

• Repair the numerous railing spindles and rail posts noted with corrosion holes. Consideration should be given to developing a programmed replacement of the deficient railing spindles and posts. • Repair the dehumidifier pedestals and in the process, increase the gap between the pedestal and underside of the dehumidifier. • Install caulking at the split collars on the stiffening truss top chords to prevent water from leaking onto the socket area below.

2020 TEN YEAR RENEWAL AND REPLACEMENT PLAN - NARRATIVE SUMMARY PAGE 6 OF 59 NEWPORT PELL BRIDGE

Additionally, RITBA plans to internally manage and perform selected weld repairs/upgrades on the bridge in 2019-2020. RITBA took a similar approach regarding the selected repainting program on the bridge in 2018. This repainting program consisted of RITBA maintenance staff overseeing internally hired union painters to address areas of a failed paint system.

Item 3: Development and Maintaining of Asset Management Program

RITBA has embarked on developing an agency wide asset management program to ensure efficient maintenance of all RITBA owned/controlled bridges, roadways and facilities. An effective asset management program prioritizes essential maintenance, repairs and rehabilitation to prolong the state of good repair of the assets and minimizes unexpected larger restoration/rehabilitation projects. The program began in 2015 with a data gathering effort on the Newport Pell Bridge using Light Detection and Ranging (LiDAR) scanning technology and a pilot program for RITBA’s landscaping work. RITBA intends to expand this program incrementally one asset at a time until all assets under RITBA’s jurisdiction are cataloged.

Item 4: Load Rating Update

A load rating is an analysis of the existing bridge that informs RITBA of the structure’s current load-carrying capacity. The rating analysis provides the overall controlling capacity for the bridge as well as the rating of each individual structural element (deck, stringers, floorbeams, truss members, suspender cables, etc.). RITBA anticipates updating the load rating of the bridge every ten years or as required based on structure modifications (structure widening, structural repairs, etc.), change in loading (updated live load vehicles; increased superimposed dead loads such as overlay pavement, added access platforms, added utilities, etc.) and/or change in condition (e.g. section loss or deterioration of primary structural members). Information gathered during the routine biennial inspections as well as supplemental special/targeted inspections are used to develop the existing conditions of the structural elements. Load ratings are an important resource when prioritizing repair projects since they identify structural members that have a below statutory load-carrying capacity. A load rating update is anticipated to be completed in 2019. Estimated costs for another update are included at the end of this ten-year period.

2020 TEN YEAR RENEWAL AND REPLACEMENT PLAN - NARRATIVE SUMMARY PAGE 7 OF 59 NEWPORT PELL BRIDGE

Item 5: Restriping

Roadway lane striping generally needs to be renewed every five years. All restriping projects are contracted out since RITBA does not own the equipment to remove and apply lane striping.

Item 6: Deck Sealing

The top surface of the exposed bridge deck exhibits constant deterioration due to vehicular wear and exposure to water and deicing salt. During the winter months, cracks in the top of the deck allow water intrusion into the deck which freezes and thaws (referred to as freeze- thaw action) with temperature fluctuation and can lead to damage/deterioration (advanced cracking, delaminations, spalls) of the deck. Additionally, the chloride ions in the deicing salt can migrate further into the concrete deck through micro cracks. Eventually the chloride ions reach the level of the steel reinforcement in the bridge deck and initiate steel corrosion, particularly when combined with water. The steel reinforcement expands due to the corrosion causing further cracking in the deck and deeper chloride ion penetration, which may lead to delamination and spalling.

Bridge deck sealing prevents chloride ions and water from entering the concrete. The Newport Pell Bridge deck has been sealed several times since the late 1980s with the last application occurring in 2012. The bridge deck should be cleaned and resealed every five to seven years to maintain this important protection. The next scheduled application is 2021- 2022 after the deck rehabilitation described in Item 7.

Item 7: Deck Partial Depth Rehabilitation (Hydrodemolition)

As detailed in Item 6, the top of the exposed bridge deck deteriorates due to vehicular wear and exposure to water and deicing salt. Partial depth rehabilitation removes the top 2” to 3½” of deteriorated concrete deck using high-pressure water to expose the top layer of steel reinforcement. The process removes the unsound, chloride contaminated concrete providing a suitable bonding surface to receive the new concrete. This method of repair is only suitable when the chloride contamination is limited to the top few inches of the deck. If high chloride levels are present at deeper depths into the deck, a more extensive full depth repair/replacement of the deck is typically warranted.

In 2000, 800 feet of the west approach deck underwent partial depth rehabilitation. Current contract 19-3 anticipates 4,500 feet of the east approach deck to be repaired between 2019 and 2021. Further deck rehabilitation is anticipated between 2024 and 2026.

2020 TEN YEAR RENEWAL AND REPLACEMENT PLAN - NARRATIVE SUMMARY PAGE 8 OF 59 NEWPORT PELL BRIDGE

Item 8: Deck Patching

Patch type repair of surface deficiencies in the top of the concrete bridge deck is an ongoing annual program which maintains a safe driving surface and prolongs the service life of the deck. The program includes the repair of visually apparent deficiencies (primarily surface spalls) as well as a proactive sounding (hammer tapping or chain drag methods) to identify and repair delaminations or incipient spalls. This annual program, along with the sealing of the bridge deck as described in Item 6, has been instrumental in preserving the concrete and extending the service life of the deck.

Photo 1 – Spalls and Previous Repairs in the Top of the Bridge Deck in the East Approach Spans

Item 9: Deck Expansion Joint and Header Repairs

Bridge deck expansion joints allow temperature related movements (expansion, contraction) of the superstructure. Deck joints allow each adjacent superstructure unit to expand with temperature rise and contract with falling temperatures. The Newport Pell Bridge has a variety of expansion joint types depending on the anticipated superstructure movement at each deck joint location. The longer suspension and truss spans have steel finger joints, which accommodate several inches of movement. The shorter floor system, prestressed concrete girder and beam spans use asphaltic plug, compression seal and strip seal deck joints, which facilitate an inch or so of movement.

The steel expansion joint armor and surrounding concrete header exhibits significant wear from the passing vehicles, particularly large trucks. Unevenness across the deck joints allows for plow damage to the joint armor (scrapes, gouges) and header (break-up, spalling). Uneven deck joints are also a source of vibration and noise that affect the rideability and comfort of the motorists. The deck joints of the approach spans exhibit isolated areas with missing portions, bulging and tears in the joint seal.

2020 TEN YEAR RENEWAL AND REPLACEMENT PLAN - NARRATIVE SUMMARY PAGE 9 OF 59 NEWPORT PELL BRIDGE

This item includes joint armor repairs, partial/full depth joint header repairs, repair/replacement of joint seals and repair of the drainage troughs underneath the finger joints. The repair of the deck joints is anticipated between 2021 and 2024.

Item 10: Deck Evaluation Study

The original 7 1/2” thick concrete bridge deck is 50 years old and contains extensive previous repairs/patches throughout. The deck has been continually inspected and deteriorated areas have been repaired as part of ongoing preventative maintenance. Items 6 through 9 in the 10-Year plan are important components of the deck maintenance/repair program and aid in maximizing the service life of the deck.

This item includes condition monitoring and testing of the concrete deck, which will include evaluation of the need for future full depth deck replacement. The condition monitoring and testing program has been in place for decades and forms the basis of determining the appropriate types and level of repairs required to best prolong the life of the deck. The program allows for RITBA to track deterioration over time. The evaluation aspects of this item include:

• Targeted condition inspections using visual techniques to identify cracks and spalls in the riding surface. • Concrete sounding (hammer tapping or chain drag) to discover delaminations. • Sampling and testing of chloride intrusion from deicing salts.

The deck evaluation is anticipated in 2026-2027.

Item 11: Median Barrier Maintenance

The original median barrier installation (contract 14-12) included a service agreement to maintain (clean, repaint guidelines and perform minor repairs) the barrier system and replace damaged barrier units until 2020. After the initial four-year maintenance period, the cost of maintenance and repair of the barrier becomes an ongoing cost to RITBA. The 10-Year Plan reflects this cost starting in 2020-2021. It is estimated that approximately five barrier units will need to be replaced yearly in addition to the general maintenance. RITBA currently has 50 spare barrier units that will likely need to be replenished during this 10- year period.

2020 TEN YEAR RENEWAL AND REPLACEMENT PLAN - NARRATIVE SUMMARY PAGE 10 OF 59 NEWPORT PELL BRIDGE

Item 12: Realignment of West Approach Roadway

The Jamestown Toll Plaza was upgraded to include open road tolling (ORT) lanes in 2012. The current toll plaza configuration consists of one ORT lane and four mixed toll lanes (cash and E-Z Pass) in each direction, which forces motorists to choose the appropriate lane as they approach the toll plaza. Drivers navigating through the plaza also need to decide whether to remain on the RI 138 Connector Highway or exit onto local roads.

The decision making is more challenging for westbound drivers approaching the toll plaza from the Newport Pell Bridge due to the less than ideal sight distance. The westbound roadway follows a curved alignment that flares out just before the plaza. The curve reduces the driver’s view of the toll plaza and corresponding signage, delaying lane choice determination until entering the toll plaza area. This creates potential safety issues, especially for trucks, which require a greater distance to react. This item intends to address this situation by realigning the westbound roadway between the Newport Pell Bridge and the toll plaza. The 10-Year Plan anticipates the west approach roadway realignment construction in 2022-2023.

Work under this item will be coordinated with Item 8: Structure “E” Superstructure Replacement and Widening in the Minor Bridges Section and Item 7: Jamestown Toll Plaza Upgrades in the Facilities Section of this 10-Year Plan.

Item 13: Removal of Loose Stringer Haunches (Combine with Appropriate Contracts)

The stringers (smaller longitudinal members spanning between transverse floorbeams) directly support the bridge deck. Typical cast-in-place deck on beam/stringer bridges are designed with a small space between the underside of the deck and the top of the steel beam/stringer top flanges, which allows for adjustments during concrete placement of the deck. This space is typically filled with unreinforced concrete and is referred to as the “haunch”.

The concrete haunches extend approximately 3 1/2” beyond the edge of the steel stringer top flanges. This unsupported overhanging portion of the haunches are prone to cracking, delamination and spalling, which presents a falling hazard. Delaminations and incipient spalls of the haunches have been routinely removed after identification during inspections. The 10-Year Plan includes a nominal cost for removing the loose haunches when access to the underside of the bridge is provided by other repair work.

2020 TEN YEAR RENEWAL AND REPLACEMENT PLAN - NARRATIVE SUMMARY PAGE 11 OF 59 NEWPORT PELL BRIDGE

Item 14: Steel Superstructure Repairs/Retrofits (Suspended Spans)

This item pertains to steel repairs identified during surface preparation for the painting of the towers, suspender ropes and main cables. Bent/broken hand rope stanchions as documented in the along the main cables will also be repaired.

Item 15: Painting of Steel Superstructure (Suspended Spans)

An effective paint system on steel members is crucial to maintaining functionality and the state of good repair of the bridge, particularly on structural elements. Once the paint system is compromised, steel corrosion will initiate rapidly due to the corrosive environment (deicing salt, seawater exposure) surrounding the bridge. If not corrected in a timely manner, steel section loss will occur and repairs will be required to maintain the structural integrity and load-carrying capacity of the members.

The effective life of any paint system depends on a variety of factors including the quality of the surface preparation, the quality/appropriateness of the paint system used on the steel, the environment and the effectiveness of the drainage system on the bridge. Painted steel located near failing or open bridge deck joints typically has a reduced service life due to roadway water runoff mixing with deicing salt. The 10-Year Plan includes painting of the towers and suspender ropes of the suspended spans

in 2021-2022 and 2022-2023. Photo 2 – Rust and rust staining on the towers.

Item 16: Main Cable Unwrapping, Repair and Dehumidification

The main cables are among the most important components of the bridge since they serve as the primary structural load path and are nonredundant structural members. Each main cable on the Newport Pell Bridge consists of numerous parallel galvanized steel wires. The wire strands are encased within a painted fiberglass (Lucite) wrapping system. Accessing the wire strand and individual wires is an intricate process required for inspection,

2020 TEN YEAR RENEWAL AND REPLACEMENT PLAN - NARRATIVE SUMMARY PAGE 12 OF 59 NEWPORT PELL BRIDGE

maintenance and repair. This process includes removing the wrapping and wedge opening the wire strand to allow access to inspect/repair the individual wires. Following the inspection/repair, the individual wires are lubricated (specially formulated oil) and compacted into the wire strand. The wire strand is then enclosed by a new elastomeric wrapping system, which is then painted.

There are a variety of contributing factors leading to main cable corrosion and eventual loss of strength. The process typically starts with the breakdown of the galvanization on the individual wires due to the reaction with infiltrated water and atmospheric pollutants. Once the galvanization is damaged, corrosion develops and weakens the wires. The high strength steel used for the cable wire is relatively brittle and prone to fracture from corrosion related section loss. Additionally, a phenomenon known as “hydrogen embrittlement” can occur whereby hydrogen atoms defuse into the steel affecting the molecular bonds of the steel, resulting in increased brittleness. These conditions can lead to breaking of individual wires even under normal stress levels.

Main cable dehumidification is a new process used to create a dry-state environment within the cable system through an active means. The system injects dried air into the cable’s sealed enclosure (wrapping) and into the void space between the individual wires. The injected dried air absorbs the water trapped within the enclosed cable system and is evacuated through exhaust ports. Research has shown that maintaining the relative humidity to a level below 60% dramatically reduces corrosion and further lowering to 40% reduces corrosion to negligible rates.

This item includes unwrapping/rewrapping, localized repairs and dehumidifying the main cables at the end of the ten-year period.

Item 17: Prestressed Concrete Girder Repairs

The ends of scattered prestressed concrete girders of the east approach spans exhibit spalls in the bottom flange with exposed and corroded steel reinforcement. This spalling typically occurs under the deck joints. The typical girder spall repair involves removing loose and deteriorated concrete, cleaning the exposed reinforcement, filling the spalled area with non-shrink repair mortar and applying a mastic and fiber wrap around the girder. Repairs were performed on numerous prestressed girders in the east approach spans under completed contract 17-3. The prestressed concrete girders repairs are assumed towards the end of the ten-year period.

2020 TEN YEAR RENEWAL AND REPLACEMENT PLAN - NARRATIVE SUMMARY PAGE 13 OF 59 NEWPORT PELL BRIDGE

Item 18: Rocker Bearing Repairs / Resetting (Deck Truss and Girder Spans)

The rocker bearings that support the superstructure must be reset periodically to correct misalignment or to release any “frozen” bearings. If a rocker bearing is not reset, tilting beyond a safe degree could occur, potentially leading to the overturning of the bearing. The 10-Year Plan includes the estimated cost of resetting select rocker bearings in 2023- 2024 to maintain safety until the bearings are eventually replaced with modern bearings under Item 19.

Item 19: Bearing Replacements (Deck Truss and Girder Spans)

The rocker bearings supporting the trusses and girders were state of the art when the bridge was constructed. However, it is now known that this type of bearing performs poorly during seismic events. Also, there are numerous rocker bearings that have become “frozen” and are not functioning as intended. Completed contract 17-3 replaced all existing steel bearings within span 33E to the east abutment with new elastomeric bearings. The 10-Year Plan includes the estimated cost of replacing rocker bearings with modern bearings that conform to current design standards.

Item 20: Pier Concrete Repairs

The pier caps and columns exhibit up to 1/4” wide cracks, scattered delaminations and scattered spalls, particularly in the west approach spans. The spalls extend up to 5” deep and have exposed reinforcement. Some concrete repairs were performed on the piers of the east approach spans under completed contract 17-3. The concrete repairs of the piers are anticipated in 2019-2020 as part of contract 19-4. Photo 3 – Cracking with Rust Staining in the Pier 11W Cap and Column

2020 TEN YEAR RENEWAL AND REPLACEMENT PLAN - NARRATIVE SUMMARY PAGE 14 OF 59 NEWPORT PELL BRIDGE

Item 21: Underwater Pier Repairs

According to the 2017 Underwater Inspection Report, scattered concrete pier columns exhibit abrasion as well as steel jacket deterioration including areas of 100% section loss. Contract 19-4 includes underwater concrete repairs to piers 1E, 17E, 19E through 21E and 34E. Fiberglass reinforced plastic (FRP) jackets will also be installed around selected pier columns as part of contract 19-4. This work is anticipated in 2019-2020.

Item 22: West Protection Cell Repairs

There are cofferdam protection cells in the water below the low point of main suspension cables where the main cables enter the anchorages. The protection cells prevent errant vessels from impacting and damaging the main cables. Each of the protection cells are formed from three circular steel sheet piling cofferdams that are filled with gravel and topped with concrete. According to the 2017 Underwater Inspection Report, the steel sheet piling typically exhibits moderate laminar rust with 1/8” section loss throughout and isolated areas of 100% section loss. The east protection cells have an outer concrete protective layer (jacket) and the west cells have a protective coating within the splash zone. The 10-Year Plan includes installation of a concrete jacket at the west protection cells.

Item 23: Security Features - Cameras and ATMS

This item pertains to the installation and future updating of cameras and an advanced traffic management system (ATMS) at various locations along the bridge. Cameras and ATMS enhance safety and security by providing RITBA with real time video and data regarding traffic flow, accidents, potential obstructions and unwarranted individuals on the bridge. The 10-Year Plan includes the estimated costs of the initial equipment installation in 2019-2020. Replacement/upgrading of selected components based on usage and technology enhancements is anticipated every three years.

2020 TEN YEAR RENEWAL AND REPLACEMENT PLAN - NARRATIVE SUMMARY PAGE 15 OF 59 NEWPORT PELL BRIDGE

Item 24: Electrical Equipment / Electrical Upgrade

Roadway lighting on the bridge is essential to driver safety as it illuminates the roadway features and potential obstructions. Similarly, US Coast Guard required navigation lighting guide vessels through the navigational channel. The aviation lights atop the suspension towers warn low flying aircraft of the obstruction, particularly in fog. The safety related lighting must always be properly functioning. The digital message sign (DMS) on the bridge warns motorists of accidents, traffic congestion, roadwork/lane closures and weather advisories. Additionally, there are Rhode Island Common Operating Picture (RICOP) servers and antennas on top of the towers, which are part of a statewide security detection system.

The current electrical system on the bridge is approximately 23 years old and has a history of outages, particularly when moisture/water fill the conduits. All the electrical loads on the bridge are served by only one medium voltage feeder. There is no emergency generator on the Newport side and if a power outage were to occur on that side, more than half of the bridge would not have electrical power. The electrical and fiberoptic systems on the bridge are scheduled for a major upgrade in 2023-2024, which will improve the reliability and redundancy of the system.

Item 25: Access Improvement

The access system in the suspended spans consists of two longitudinal steel catwalks with intermittent transverse crossovers. The catwalks are utilized for inspections and maintenance. There is advanced section loss including areas of 100% section loss in the longitudinal support channels, diaphragms and transverse struts of the catwalks. There are numerous areas of bending/misalignment of the floor plate, kick plates and rails. The steel catwalk in the floor system and deck truss spans is in similar but less severe condition as the catwalk in the suspended spans.

An access improvement project is anticipated in this ten-year period and will include repair/replacement of deteriorated catwalk members as well as expansion of the catwalk system to other points of interest on the superstructure. The points of interests will be areas routinely accessed for maintenance and inspection such as the underside of the deck joints and along the pier caps.

2020 TEN YEAR RENEWAL AND REPLACEMENT PLAN - NARRATIVE SUMMARY PAGE 16 OF 59 NEWPORT PELL BRIDGE

Item 26: Tower Elevators Replacement / Upgrade

Each tower has an internal elevator in one the tower legs that extends from the roadway level to approximately 60 feet from the top of the tower. These internal elevators are from the original construction of the bridge and are 50 years old. The elevators are routinely maintained and do not conform to current design standards.

There narrow access hatches into/out of the elevator and the access hatch at the top of the elevator only provides 12” of horizontal clearance. This reduced clearance forces inspectors and maintenance staff to squeeze through the hatch to enter/exit the elevator and limits the equipment that can be taken in the elevator. This item includes the replacement of the existing elevators with ones that conform to current design standard as well as the improvement of the access into/out of the elevator.

Photo 4 – Reduced Clearance at the Top of the Elevator within the Newport Pell Bridge Tower

Item 27: West Approach Curb Replacement

Select deteriorated sections of the concrete curb on the west approach roadway of the Newport Pell Bridge are scheduled to be replaced as part of contract 19-4.

2020 TEN YEAR RENEWAL AND REPLACEMENT PLAN - NARRATIVE SUMMARY PAGE 17 OF 59 MOUNT HOPE BRIDGE

MOUNT HOPE BRIDGE

The Mount Hope Bridge opened to traffic on October 24, 1929 and carries RI 114 over the Mount Hope Bay between the towns of Bristol on the mainland and Portsmouth on Aquidneck Island. The bridge also spans over Old Ferry Road in Bristol and an unnamed road between Bristol Ferry Road and Mussel Bed Shoal Road in Portsmouth. This 31-span bridge has a total structure length of 6,130 feet, which includes 3 suspension spans and 28 steel floor system (girder-floorbeam-stringer) approach spans. The main suspension span is 1,200 feet long and the two side suspension spans are 504 feet each. The steel towers of the suspension spans extend 285 feet above the water. With a main span of 1,200 feet, the Mount Hope Bridge once had the longest span in New England.

Structures included:

Mount Hope Bridge Steel suspension bridge for 3 spans and steel floor system for 28 spans (6,130 ft. total length)

As shown in the above chart, the main cable rehabilitation and dehumidification, and the superstructure repairs and painting account for roughly 40% of the anticipated costs in this ten-year period. This percentage of expenditures is typical for a bridge of this age and structure complexity. Wearing surface replacement and bridge deck repairs comprise approximately 27% of the future costs. The last bridge deck replacement occurred in 1986.

Item 1: Future Repairs / Minor Rehabilitation On-Call Contract

This item reflects an on-going, smaller scale repair program to address items identified during bridge inspections that should not wait until a larger repair program can be

2020 TEN YEAR RENEWAL AND REPLACEMENT PLAN - NARRATIVE SUMMARY PAGE 18 OF 59 MOUNT HOPE BRIDGE

initiated. This item also includes smaller scale studies and testing programs which provides information to RITBA for use when developing and prioritizing larger repair/rehabilitation programs.

Examples of repairs, as recommended in the 2018 Biennial Inspection Report, which could be performed under this item include:

• Repair areas of significant section loss and/or corrosion holes in the steel girders, floorbeams, stringers, bracing and bents. • Repair areas of section loss and crevice corrosion found throughout the girder hinge bearings. • Repair spalled and unsound areas of the reinforced concrete pier columns and cross struts, and monitor cracks.

Photo 5 – Hinge Bearing of the East Girder in the South Approach Spans

Item 2: Miscellaneous Maintenance and Repairs

This item includes maintenance projects that are not covered in the specific items below. These projects are beyond the scope of routine maintenance tasks. Examples of repairs, as recommended in the 2018 Biennial Inspection Report, which could be performed under this item include:

• Remove all loose stay-in-place forms below the safety walks on an annual basis. • Extend all downspouts of the scuppers within the suspended spans below the stiffening truss to divert water away from the catwalks and stiffening trusses. • Install rain deflector hoods along the top vent of each tower leg at the top struts to prevent water infiltration into the tower legs.

Additionally, RITBA plans to internally manage and perform the repainting of selected areas of the bridge in 2019-2020 and 2026-2027. RITBA successfully completed a similar selected repainting program on the Newport Pell Bridge in 2018.

2020 TEN YEAR RENEWAL AND REPLACEMENT PLAN - NARRATIVE SUMMARY PAGE 19 OF 59 MOUNT HOPE BRIDGE

Item 3: Development and Maintaining of Asset Management Program

The asset management program inventories all RITBA bridges and related expenditures. An effective asset management program prioritizes essential maintenance, repairs and rehabilitation to prolong the state of good repair of the bridge and minimizes unexpected larger restoration/rehabilitation projects. The program will be periodically expanded and maintained.

Item 4: Load Rating Update

RITBA anticipates updating the load rating of the bridge every ten years or as required based on structure modifications (structure widening, structural repairs, etc.), change in loading (updated live load vehicles; increased superimposed dead loads such as overlay pavement, added access platforms, added utilities) and/or change in condition (e.g. section loss or deterioration of primary structural members). The 10-Year plan includes funding to update the load rating report approximately ten years from the date of the previous load rating report.

Item 5: Restriping

Roadway lane striping generally needs to be renewed every five years. All restriping projects are contracted out since RITBA does not own the equipment to remove and apply lane striping.

Item 6: Deck and Miscellaneous Concrete Repairs

The Mount Hope Bridge’s narrow roadway (one travel lane in each direction) intensifies the importance of having an effective bridge deck repair program due to the difficulty of maintaining traffic during construction activities. During complete deck replacements, a portion or the entire bridge must be taken out of service requiring lengthy lane closures or detours that could result in significant delays for the traveling public. The last complete deck replacement for the Mount Hope Bridge was in 1986. During the 1986 deck replacement, the bridge was completely closed to traffic for five months resulting in an up to 25-mile or 40-minute traffic detour to motorists commuting between Bristol and Portsmouth.

2020 TEN YEAR RENEWAL AND REPLACEMENT PLAN - NARRATIVE SUMMARY PAGE 20 OF 59 MOUNT HOPE BRIDGE

The bridge deck consists of a 4 1/4” thick concrete filled steel grid deck with an additional 2” thick concrete overfill. A thin layer of rubberized asphaltic chip seal has been placed over the concrete overfill to function as the wearing surface. This item pertains to the routine deck repairs/patching with the next repairs occurring between 2019 and 2021. Another round of deck repairs are anticipated at the end of this 10-Year Plan.

Photo 6 – Narrow Roadway and Wearing Surface with Repairs on the Mount Hope Bridge

Item 7: Wearing Surface Replacement including Deck Concrete Infill Repairs

The wearing surface consists of a thin layer of rubberized asphaltic chip seal that has been placed over the concrete overfill above the concrete filled steel grid deck. The wearing surface is in fair to satisfactory condition based on the 2018 Biennial Inspection Report. The wearing surface and top of the bridge deck generally deteriorates first due to water and deicing salt intrusion. Targeted deck samples (cores) will be taken and tested as part of the design process to assess the level of chloride ion intrusion. This item includes the removal of the chip seal, the 2” overfill layer and any loose/unsound concrete material within the concrete filled steel grid deck. A thin wearing surface will be reapplied/installed throughout the bridge. Completed contract 16-7 included the installation of various deck/wearing surface materials as test cases for a future wearing surface replacement. The performance of these various test materials will be considered when determining the type of the future wearing surface.

2020 TEN YEAR RENEWAL AND REPLACEMENT PLAN - NARRATIVE SUMMARY PAGE 21 OF 59 MOUNT HOPE BRIDGE

Item 8: Main Cable Rehabilitation and Dehumidification, and New Anchorage Dehumidification System

The main cables are among the most important components of the bridge since they serve as the primary structural load path and are nonredundant structural members. Each main cable on the Mount Hope Bridge contains 2,450 individual steel wires bundled in 7 strands of 350 parallel wires. Each wire strand is wrapped with a steel wrapping wire. The galvanized (zinc coated) steel wires are standard No. 6 gauge (0.196” diameter). The wire strands are enclosed by the steel wrapping wire. Accessing the wire strand and individual wires is an intricate process required for inspection, maintenance and repair. This process includes removing the wrapping wire and wedge opening the wire strands to allow access to inspect/repair the individual wires. Following the inspection/repair, the individual wires are lubricated (specially formulated oil) and compacted into the wire strands. The wire strands are then enclosed by new wrapping wire, which is then painted.

In 2015, a targeted inspection was performed on the main cables by engineering consulting firm Ammann and Whitney which included individual wire inspection. A subsequent cable investigation and evaluation report was developed in 2016. Part of the summary of the 2016 Cable Investigation and Evaluation Report states: These cables have a well-documented history of stress-corrosion cracking due to the depletion of zinc protection and ferrous corrosion…Dehumidifying the cables, we believe, is the most effective way of prolonging the life of the cables, theoretically indefinitely. The cables are in a stage where areas of the zinc layer are nearly depleted, which has historically resulted in stress-corrosion cracking at this bridge. Without a proactive effort to stop the zinc depletion, the wires will deteriorate at an accelerated pace.

The last main cable rehabilitation occurred between 1999 and 2001 (main suspended span) and 1995 (side suspended spans). Main cable rehabilitation involves the same access process as detailed above and typically includes the splicing of replacement individual wires at broken or heavily deteriorated locations.

As detailed in Item 16 of the Newport Pell Bridge, individual wire corrosion and section loss is typically caused from the breakdown of the galvanization coupled with the infiltration of water and atmospheric pollutants. Main cable dehumidification can dramatically reduce the corrosion of the individual wires. Similarly, anchorage dehumidification systems regulate the moisture levels of the strands within the anchorages to prevent further corrosion of the cable wires at this critical location.

2020 TEN YEAR RENEWAL AND REPLACEMENT PLAN - NARRATIVE SUMMARY PAGE 22 OF 59 MOUNT HOPE BRIDGE

Item 9: Suspended Spans Miscellaneous Steel Repair

According to the 2018 Biennial Inspection Report, the stringers, floorbeams and stiffening trusses in the suspended spans are in fair to satisfactory condition with areas of peeling paint, surface corrosion, localized section loss and crevice section loss between connected steel plates. Some notable conditions detailed in the 2018 Biennial Inspection Report are:

• Floorbeams: The floorbeams have a number of scattered areas with painted over section losses, between 1/8” and 3/8”. • Stiffener Truss Bottom Chords: There are also numerous locations where crevice corrosion, up to 3/4”, exists between the gusset plates and bottom chord flange angles with adjacent section loss up to 3/16” in the vertical legs of the flange angles. • Stiffener Truss Vertical Web Members: The vertical members of the stiffening truss typically exhibit numerous areas with mainly inactive section losses ranging from 1/8” to 5/8” with numerous locations noted with corrosion holes in the web of the verticals. • Stiffener Truss Gusset Plates: Along the inboard faces of the inboard top chord gusset plates, there are isolated areas of painted over section loss, up to 5/16” deep, typically found between the top flange of the floorbeam and the underside of the safety walks.

This item would address the more significant conditions as identified in future inspection reports and is anticipated to occur in the last half of this 10-Year Plan.

Item 10: Main Cable and Suspender Rope Painting / Cable Band Caulking

As detailed in Item 8, maintaining the structural integrity of the main cables requires keeping water and pollutants out of the cable system. Water can infiltrate through the paint system on the cable wrapping and through defects in the caulked joints around the edges of the cable bands, which connect the suspender ropes to the main cable.

This item involves the replacement of deteriorated and aging caulking material around the perimeter of the cable bands, and the surface preparation/painting of the wrapping of the main cables. The suspender ropes will also be painted as part of this item.

2020 TEN YEAR RENEWAL AND REPLACEMENT PLAN - NARRATIVE SUMMARY PAGE 23 OF 59 MOUNT HOPE BRIDGE

Item 11: Tower and North Approach Bent Painting

The steel towers of the suspended spans were last painted in 2006 and 2007. The steel bents in the north approach spans were last painted in 2002. This 10-Year Plan includes estimated painting costs in 2028-2029.

Item 12: Security Features - Cameras and ATMS

This item pertains to the installation and future updating of cameras and an ATMS at various locations along the bridge. Cameras and ATMS enhance safety and security by providing RITBA with real time video and data regarding traffic flow, accidents, potential obstructions and unwarranted individuals on the bridge. The 10-Year Plan includes the estimated costs of the initial equipment installation between 2019 and 2022. Replacement/upgrading of selected components based on usage and technology enhancements is anticipated every three years.

Item 13: Electrical Equipment / Electrical Upgrade

As detailed in Item 24 of the Newport Pell Bridge, safety related lighting must always be properly functioning. There is roadway, navigation and aviation lighting on the Mount Hope Bridge. Repair, replacement and upgrade of deficient roadway, navigation and aviation lighting components are anticipated at a three-year frequency. The electrical and fiberoptic conduits on the bridge are scheduled for a major upgrade at the end of this ten- year period.

Two new digital message signs (DMS) are anticipated to be installed on the bridge, one each in 2019-2020 and 2021-22. One DMS will be on the Bristol side and the other on the Portsmouth side. These signs can be used to warn motorists of accidents, traffic congestion, roadwork/lane closures and weather advisories.

Item 14: Access Improvement

The steel catwalk in spans 8 through 27 provides access to the underside of the superstructure. The 2018 Biennial Inspection Report stated:

The maintenance catwalk along the suspended spans (Spans 18 to 20) is generally in fair to satisfactory condition; however, there are numerous locations that exhibit severe section losses that have

2020 TEN YEAR RENEWAL AND REPLACEMENT PLAN - NARRATIVE SUMMARY PAGE 24 OF 59 MOUNT HOPE BRIDGE

compromised the structural capacity of the catwalk support channels. Due to the areas of severe section losses found at various locations, the catwalks are not safe for general use in their current condition.

A subsequent catwalk survey was performed by engineering consulting firm Modjeski and Masters, Inc. in December 2018. There is advanced section loss including areas of 100% section loss/corrosion holes in the longitudinal support channels, transverse support angles, rails and rail posts. Scattered bearing bars of the grating have advanced section loss including 100% section loss. Numerous areas of the kick plate angle are broken/angle. Selected severely deteriorated steel grating panels (120 ft. in total) will be replaced by fiberglass composite panels in 2019-2020. Additionally, selected severely deteriorated support members and components will be repaired in 2019-2020 and 2019-2021. A significant catwalk project is anticipated in the last half of this 10-Year Plan which will include repair/replacement of deteriorated members as well as expansion of the catwalk system to other points of interest on the superstructure. The points of interests will be areas routinely access for maintenance and inspection such as the underside of the deck joints and along the bent caps.

Access to the top of the north anchorage chamber is currently achieved by an extension ladder, aerial lift or underbridge inspection unit (UBIU). A permanent exterior stair tower on the east side of the chamber is anticipated to be installed in 2019-2020 and will eliminate the need for access equipment to enter the chamber.

Photo 7 – East Elevation of the North Anchorage Chamber

Item 15: North Anchorage and Staging Area Fence

A chain link fence will be installed around the north anchorage chamber and staging area on the Bristol side. This fence will minimize unwarranted access to the bridge. The fence is anticipated to be installed in 2019-2020.

2020 TEN YEAR RENEWAL AND REPLACEMENT PLAN - NARRATIVE SUMMARY PAGE 25 OF 59 SAKONNET RIVER BRIDGE

SAKONNET RIVER BRIDGE

The Sakonnet River Bridge opened to traffic in 2012 and carries RI 24/138 over the Sakonnet River between the towns of Portsmouth on Aquidneck Island and Tiverton on the mainland. The bridge also spans over Riverside Avenue in Portsmouth and Riverside Drive and Tucker Avenue in Tiverton. This ten-span bridge has a total structure length of 2,265 feet. The bridge has seven continuous main spans consisting of four steel trapezoidal box girders. There are two approach spans in Portsmouth and one in Tiverton each comprised of ten prestressed concrete New England Bulb Tee (NEBT) beams. In all spans, there is a reinforced concrete deck composite with the girders/beams, which supports the bituminous concrete wearing surface and reinforced concrete parapets/barriers. A bike path is carried along the north side of the bridge.

Structures included:

Sakonnet River Bridge Multi steel trapezoidal box girders for seven spans and multi prestressed concrete NEBT beams for three spans (2,265 ft. total length) Boat Ramp Concrete boat ramp with floats and parking and fishing areas

As shown in the chart above, bridge inspections at 18% comprise the largest single anticipated expenditure. Security feature, weather station and electrical upgrades encompass roughly 15% of the anticipated costs in this ten-year period. The remaining 67% represents various improvements and repair projects.

2020 TEN YEAR RENEWAL AND REPLACEMENT PLAN - NARRATIVE SUMMARY PAGE 26 OF 59 SAKONNET RIVER BRIDGE

Item 1: Future Repairs / Minor Rehabilitation On-Call Contract

This item reflects an on-going, smaller scale repair program to address items identified during bridge inspections that should not wait until a larger repair program can be initiated. This item also includes smaller scale studies and testing programs which provides information to RITBA for use when developing and prioritizing larger repair/rehabilitation programs.

Examples of repairs, as recommended in the 2018 Biennial Inspection Report, which could be performed under this item include:

• Repair/replace damage sections of pedestrian and approach railings. • Install tie-off hooks at box girder access hatches. • Replace broken control springs for the deck joints.

Item 2: Miscellaneous Maintenance and Repairs

This item includes maintenance projects that are not covered in the specific items below. These projects are beyond the scope of routine maintenance tasks. Examples of repairs, as recommended in the 2018 Biennial Inspection Report, which could be performed under this item include:

• Tighten loose supports for the scupper downspouts. • Install missing junction boxes covers, reconnect separated utilities and tighten/install loose/missing connection screws/bolts for the utilities. • Install screens at the weep holes in the box girder bottom flanges.

Item 3: Development and Maintaining of Asset Management Program

The asset management program inventories all RITBA bridges and related expenditures. An effective asset management program prioritizes essential maintenance, repairs and rehabilitation to prolong the state of good repair of the bridge and minimizes unexpected larger restoration/rehabilitation projects. The program will be periodically expanded and maintained.

2020 TEN YEAR RENEWAL AND REPLACEMENT PLAN - NARRATIVE SUMMARY PAGE 27 OF 59 SAKONNET RIVER BRIDGE

Item 4: Load Rating Update

RITBA anticipates updating the load rating of the bridge every ten years as required based on structure modifications (structure widening, structural repairs, etc.), change in loading (updated live load vehicles; increased superimposed dead loads such as overlay pavement, added access platforms, added utilities) and/or change in condition (e.g. section loss or deterioration of primary structural members). The 10-Year plan includes funding to update the load rating report approximately ten years from the date of the previous load rating report.

Item 5: Restriping

Roadway lane striping generally needs to be renewed every five years. All restriping projects are contracted out since RITBA does not own the equipment to remove and apply lane striping.

Item 6: Wearing Surface and Approach Pavement Crack Sealing

Crack sealing prolongs the life of the bituminous concrete wearing surface and approach pavement by reducing the paths of water infiltration onto the bridge deck or roadway subbase below. Infiltrated water collects on the bridge deck potentially deteriorating (delamination, spalling, punky concrete) the top of the bridge deck. Infiltrated water collects on the roadway subbase and can cause localized erosion and/or settlement. During the winter months, the freeze-thaw action of collected water on the bridge deck/roadway subbase can lead to deterioration (advanced cracking, bituminous break-up, potholes) of the wearing surface/pavement above. Wearing surface and approach pavement crack sealing is anticipated to occur on a five-year frequency.

Item 7: Concrete Deck Repairs

As previously described for the other bridges, the deck repair program is essential for prolonging the service life of the bridge deck and delaying the need for a vastly more expensive complete deck replacement. During complete deck replacements, a portion of the bridge must be taken out of service requiring lengthy lane closures that could result in significant delays and/or detours for the traveling public. The deck repairs are anticipated to occur on a three-year frequency.

2020 TEN YEAR RENEWAL AND REPLACEMENT PLAN - NARRATIVE SUMMARY PAGE 28 OF 59 SAKONNET RIVER BRIDGE

Item 8: Concrete Barrier/Parapet Repairs and Sealing

In 2015, engineering consulting firm Ammann & Whitney prepared a report for RITBA titled “New Sakonnet River Bridge Parapet Crack Investigation”. The study identified sources of the premature cracking in the reinforced concrete barriers and parapets and provided recommendations for short- and long-term repairs. The following summarizes their findings:

The new Sakonnet River Bridge parapet cracking seems to be the result of the use of the wrong concrete mix design, inadequate and improper curing and finishing techniques performed/utilized by the contractor, and a lack of stringent construction inspection enforcement. Without a dedicated effort by the owner to repair the existing cracks and perform maintenance as new cracks form, the parapets will exhibit accelerated deterioration. However, with the implementation of long-term maintenance plan that is adhered to, these issues can be lessened and managed. Photo 8 – Unsealed Crack in Parapet Prior to Repairs

The short-term recommendations include repairing all wide cracks using an epoxy-type material injection repair intended to remain flexible. There are hairline (very fine) cracks throughout the barriers and parapets that are too narrow for an injection type repair. To address this condition, the entire exposed surface of the concrete should be sealed with a penetrating low-viscosity sealant. Due to unappealing appearance of injection crack repairs, a coating should to be applied over the entire surface area to provide a uniform appearance. The first round of barrier/parapet repairs and sealing was completed in 2018. Subsequent barrier/parapet repairs and sealing are expected to occur on a five-year frequency.

2020 TEN YEAR RENEWAL AND REPLACEMENT PLAN - NARRATIVE SUMMARY PAGE 29 OF 59 SAKONNET RIVER BRIDGE

Photo 9 – Sealed and Coated Barrier between the Westbound Roadway and the Bike Path.

Additional cracking in the barriers and parapets is anticipated in throughout its service life, which may require more frequent repairs than would normally be expected for a bridge of this age. The 10-Year Plan includes estimated costs of concrete repairs in 2023-2024.

Item 9: Security Features – Cameras and ATMS

This item pertains to the installation and future updating of cameras and an ATMS at various locations along the bridge. Cameras and ATMS enhance safety and security by providing RITBA with real time video and data regarding traffic flow, accidents, potential obstructions and unwarranted individuals on the bridge. The 10-Year Plan includes the estimated costs of the initial equipment installation in 2019-2020 and 2020-2021. Replacement/upgrading of selected components based on usage and technology enhancements is anticipated every three years.

Item 10: Electrical Equipment/Electrical Upgrade

As detailed in Item 24 of the Newport Pell Bridge, safety related lighting must always be properly functioning. There is roadway and navigation lighting on the Sakonnet River Bridge. Repair, replacement and upgrade of deficient roadway and navigation lighting components are anticipated at a three-year frequency. Additionally, two new digital message signs (DMS) are anticipated to be installed on the bridge in 2020-2021. These

2020 TEN YEAR RENEWAL AND REPLACEMENT PLAN - NARRATIVE SUMMARY PAGE 30 OF 59 SAKONNET RIVER BRIDGE

signs can be used to warn motorists of accidents, traffic congestion, roadwork/lane closures and weather advisories.

Photo 10 - Roadway Lighting on the Sakonnet River Bridge

Item 11: MSE Walls Maintenance

This item addresses additional maintenance required for the mechanically stabilized earth (MSE) breastwalls, wingwalls and retaining walls for the bridge. The 10-Year Plan includes anticipated maintenance for the MSE walls in 2020-2021 and 2023-2024.

Item 12: Anode Replacement for Piles

Three of the bridge piers within the Sakonnet River have cathodic protection on the exposed concrete filled steel pipe piles. Cathodic protection prevents against the common accelerated steel corrosion associated with brackish environments (saltwater). The cathodic protection on the steel pipe piles consists of attached sacrificial aluminum zinc indium anodes on the exterior of the pile, which corrodes in place of the steel pile. The anodes corrode/deteriorate and will need to be replaced to ensure that steel pipe pile corrosion does not initiate. The 10-Year Plan forecasts anode replacement in 2025-2026. The actual anode replacement schedule will be influenced by the findings of the 2024 underwater inspection.

2020 TEN YEAR RENEWAL AND REPLACEMENT PLAN - NARRATIVE SUMMARY PAGE 31 OF 59 SAKONNET RIVER BRIDGE

Item 13: Access Improvement

A fixed ladder and limited catwalk will be installed on the Portsmouth side to enhance access to the underside of the bridge and the interior of the box girders. Currently, access into the box girders for inspections and maintenance is achieved by an aerial lift or underbridge inspection unit (UBIU). The box girder access hatches on the Portsmouth side are located above the embankments of the river, which is underwater during high tides limiting usage of an aerial lift. Use of an UBIU requires a lane closure on the bridge impacting the normal flow of traffic. RITBA owns one UBIU and uses short-term rentals when the concurrent need for multiple UBIUs arise. The fixed ladder and catwalk will allow access inside the box girders without the need of costly access equipment or lane closures as well as not being dependent on the river’s tide fluctuation. The fixed ladder and catwalk are anticipated to be installed in 2019-2020.

2020 TEN YEAR RENEWAL AND REPLACEMENT PLAN - NARRATIVE SUMMARY PAGE 33 OF 59 JAMESTOWN VERRAZZANO BRIDGE

JAMESTOWN VERRAZZANO BRIDGE

The Jamestown Verrazzano Bridge opened to traffic in 1992 and carries RI 138 over the West Passage of Narragansett Bay between the towns of North Kingstown on the mainland and Jamestown on Conanicut Island. The bridge also spans over Seaside Drive in Jamestown. This 52-span bridge has a total structure length of 7,353 feet, which includes the main structure (4,950 feet) and a trestle structure (2,403 feet). The main structure has 23 spans comprised of a single double-cell post-tensioned concrete trapezoidal box girder that is separated into the west approach spans (spans 1 to 11), main spans (spans 12 to 14) and east approach spans (spans 15 to 23). Three types of construction techniques were utilized during the construction of the trapezoidal box girder in the main structure: shored cast-in-place construction (spans 1, 20 and 23), precast segmental that were lifted into place (spans 2 to 11 and spans 15 to 19), and balanced cantilever that were cast-in- place (spans 12 to 14). The trestle structure has 29 spans comprised of multi AASHTO Type IV prestressed concrete girders arranged in four span continuous units.

Structures included:

Jamestown Verrazzano Single double-cell post-tensioned concrete trapezoidal box Bridge girder for 23 spans and multi AASHTO Type IV prestressed concrete girders for 29 spans (7,353 ft. total length)

As shown in the above chart, wearing surface sealing, repairs and replacement, and deck joint repair/replacement account for roughly 20% of the anticipated costs in this ten-year

2020 TEN YEAR RENEWAL AND REPLACEMENT PLAN - NARRATIVE SUMMARY PAGE 34 OF 59 JAMESTOWN VERRAZZANO BRIDGE

period, which is indicative of a structure with a 30-year service life. Post-tensioned concrete box girder repairs and survey, and pier/bent repairs comprise approximately 17% of the future costs. Bridge and pedestrian railings painting and repairs account for 16% of the anticipated expenditure in this ten-year period. Inspections comprise 17% of the future investment.

Item 1: Future Repairs / Minor Rehabilitation On-Call Contract

This item reflects an on-going, smaller scale repair program to address items identified during bridge inspections that should not wait until a larger repair program can be initiated. This item also includes smaller scale studies and testing programs which provides information to RITBA for use when developing and prioritizing larger repair/rehabilitation programs.

Examples of repairs, as recommended in the 2017 Biennial Inspection Report, which could be performed under this item include:

• Repair/replace torn elastomeric bearings. • Implement a crack monitoring program for the post-tensioned concrete trapezoidal box girders and AASHTO Type IV prestressed concrete girders.

Item 2: Miscellaneous Maintenance and Repairs

This item includes maintenance projects that are not covered in the specific items below. These projects are beyond the scope of routine maintenance tasks. Examples of repairs, as recommended in the 2017 Biennial Inspection Report, which could be performed under this item include:

• Repair spalls in the abutments. • Install missing ID signs on the piers. Photo 14 – Spall with Exposed Reinforcement in the West Abutment

2020 TEN YEAR RENEWAL AND REPLACEMENT PLAN - NARRATIVE SUMMARY PAGE 35 OF 59 JAMESTOWN VERRAZZANO BRIDGE

Item 3: Development and Maintaining of Asset Management Program

The asset management program inventories all RITBA bridges and related expenditures. An effective asset management program prioritizes essential maintenance, repairs and rehabilitation to prolong the state of good repair of the bridge and minimizes unexpected larger restoration/rehabilitation projects. The program will be periodically expanded and maintained.

Item 4: Load Rating Update

RITBA anticipates updating the load rating of the bridge every ten years or as required based on structure modifications (structure widening, structural repairs, etc.), change in loading (updated live load vehicles; increased superimposed dead loads such as overlay pavement, added access platforms, added utilities, etc.) and/or change in condition (e.g. section loss or deterioration of primary structural members). The 10-Year plan includes funding to update the load rating report approximately ten years from the date of the previous load rating report.

Item 5: Restriping

Roadway lane striping generally needs to be renewed every five years. All restriping projects are contracted out since RITBA does not own the equipment to remove and apply lane striping.

Item 6: Concrete Wearing Surface Sealing

Cracks in the latex modified concrete (LMC) overlay wearing surface allow infiltrated water and deicing salt to collect on the bridge deck potentially deteriorating both the wearing surface and top of the bridge deck. During the winter months, the freeze-thaw action of collected water on the deck can lead to deterioration (advanced cracking, break-up, spalls) of the wearing surface above. The chloride ions in the deicing salt can migrate further into the concrete deck through micro cracks. Eventually the chloride ions reach the level of the steel reinforcement and post-tensioning strands in the bridge deck and initiate steel corrosion, particularly when combined with water. The steel reinforcement and post- tensioning strands expand due to the corrosion causing further cracking in the deck and deeper chloride ion penetration, which may lead to delamination and spalling of the deck.

2020 TEN YEAR RENEWAL AND REPLACEMENT PLAN - NARRATIVE SUMMARY PAGE 36 OF 59 JAMESTOWN VERRAZZANO BRIDGE

Advanced spalling and/or section loss of reinforcement/post-tensioning strands may occur at locations of prolonged water and deicing salt intrusion. Sealing the concrete wearing surface prevents the flow of water and chloride ions onto the deck and prolongs the service life of the both the wearing surface and deck. Wearing surface sealing is anticipated to occur on a five-year frequency.

Item 7: Concrete Wearing Surface Repairs/Patching

This item consists of repairing delaminations, spalls and deteriorated areas in the concrete overlay wearing surface with an impervious, durable mortar. Repairs/patching the wearing surface of the main structure is of paramount importance to avoid corrosion of the steel post-tensioning strands in the bridge deck.

Item 8: Deck Expansion Joint Repair/Replacement (Main Structure)

The deck joints of the main structure are steel finger joints, which allow several inches of movement. The joint armor of the finger joints experiences significant wear from the passing vehicles, particularly large trucks. Unevenness across the deck joints allows for plow damage to the joint armor (scrapes, gouges) and header (break-up, spalling). The neoprene drainage troughs beneath the finger joints typically have sand and debris accumulation, and isolated tears. Localized repair of the deck joints in the main structure is anticipated in 2019-2020 as part of contract 19-4. The 10-Year plan includes estimated costs for potential future major repairs or replacement of the main structure deck joints.

2020 TEN YEAR RENEWAL AND REPLACEMENT PLAN - NARRATIVE SUMMARY PAGE 37 OF 59 JAMESTOWN VERRAZZANO BRIDGE

Item 9: Deck Expansion Joint Repair/Replacement (Trestle Structure)

The trestle structure has deck expansion joints at piers 1, 5, 9, 13, 17, 21 and 25. The strip seal deck joints have localized areas of a dislodged/torn joint seal and/or damaged/detached/missing rubber joint header. The repair or replacement of the deck joints in the trestle structure is anticipated in 2023-2024.

Photo 16 – Damaged Section of Rubber Joint Header for a Deck Joint in the West Approach Spans

Item 10: Wearing Surface and Deck Monitoring Study

The 10-Year plan includes a sampling and testing program to assess the progression of chloride ion penetration into the LMC overlay wearing surface and concrete bridge deck. A similar program was performed in 2006, but new data is required to evaluate the progression of chloride contamination. The LMC wearing surface has a finite service life and monitoring of chloride ion levels along with visual condition assessments will be used to determine when full replacement of the wearing surface will be required. A monitoring study is anticipated in 2019-2020 and 2026-2027.

Item 11: Concrete Wearing Surface Replacement

Based on the findings from the wearing surface and deck monitoring study, a wearing surface replacement may be required. The existing LMC overlay wearing surface is from the original construction of the bridge and is approximately 30 years old. The wearing surface replacement will require extensive lane closures to allow proper cure time for concrete placement.

Item 12: Bridge and Pedestrian Railings Painting and Repairs

The bridge and pedestrian railings are essential safety features that protect motorists and pedestrians using the bridge. The paint system has failed throughout the bridge and pedestrian railings.

The following are examples of repairs that can be included under this item as recommended in the 2017 Biennial Inspection Report:

• Repair bridge railing sections with collision damage. • Install missing connection bolts for the top rail of the bridge railing. • Repair, replace and/or tighten loose pedestrian railing spindles and anchor bolts.

Photo 17 – Failed Paint System on the North Bridge and Pedestrian Railings in the West Approach Spans

Item 13: Post-Tensioned Concrete Box Girder Profile Geometric Survey (Main Structure)

Cracking in the post-tensioned concrete trapezoidal box girders identified in the 2017 Biennial Inspection Report suggests that the bridge is still undergoing long term deformations due to creep and shrinkage, which is expected for this structure type. This item includes preforming an updated topometric survey, which was last completed in 2006. Past surveys have shown a consistency between the actual creep deflection and the theoretical long-term creep deflection prediction. The results of the survey and prediction will serve as the basis of comparison for future surveys. The survey profile and prediction are anticipated in 2019-2020.

2020 TEN YEAR RENEWAL AND REPLACEMENT PLAN - NARRATIVE SUMMARY PAGE 39 OF 59 JAMESTOWN VERRAZZANO BRIDGE

Item 14: Post-Tensioned Concrete Box Girder Repairs (Main Structure)

The post-tensioned concrete trapezoidal box girder has numerous cracks in the interior and exterior surfaces. The exterior surface of the box girder has isolated minor spalls and delaminations. This item includes the crack repair by epoxy injection, monitoring of non- repaired cracks and spall/delamination repairs. These repairs are anticipated in 2019-2020 as part of contract 19-4, and typically occur on a four-year frequency.

The following are examples of repairs that can be included under this item as recommended in the 2017 Biennial Inspection Report:

• Patch all minor spalls and delaminations throughout the exterior surfaces of the box girders. • Repair all cracks greater than 0.006” wide throughout the exterior surfaces of the box girders with epoxy injection. • Repair all cracks greater than 0.01” wide throughout the interior surfaces of the box girders with epoxy injection. • Monitor all cracks, especially those greater than 0.006” wide.

Item 15: Prestressed Concrete Girder Repairs (Trestle Structure)

The ends of scattered prestressed concrete girders of the trestle structure exhibit spalls in the bottom flange with exposed and corroded steel reinforcement. This spalling typically occurs at bents which are under the deck joints. The typical girder spall repair involves removing loose and deteriorated concrete, cleaning the exposed reinforcement, filling the spalled area with non-shrink repair mortar and applying a mastic and fiber wrap around the girder. Prestressed concrete girder repairs are anticipated every five years with the next repairs occurring in 2019-2020 as part of contract 19-4.

Item 16: Bearing Pad and Plinth Concrete Repairs (Main Structure)

The reinforced concrete pads (below) and plinths (above) the bearings of the post- tensioned concrete trapezoidal box girders exhibit scattered delaminations, corner spalls and previous repairs. Numerous bearing pads and plinths have cracking, isolated with previous epoxy crack injection. The spalls extend up to 4 1/2” deep and isolated spalls have

2020 TEN YEAR RENEWAL AND REPLACEMENT PLAN - NARRATIVE SUMMARY PAGE 40 OF 59 JAMESTOWN VERRAZZANO BRIDGE

exposed reinforcement. Repairs of these deficiencies will aid in maintaining the structural integrity of the substructure. The repairs are anticipated in 2020-2021 as part of contract 19-4.

Item 17: Pier/Bent Concrete Repairs

The reinforced concrete pier/bent caps and pier columns have numerous cracks, scattered delaminations and scattered spalls. The spalls extend up to 4 1/2” deep and isolated spalls have exposed reinforcement. Repairs of these deficiencies will aid in maintaining the structural integrity of the substructure. The first round of repairs is anticipated in 2020- 2021 as part of contract 19-4. The second round of repairs are anticipated towards the end of this ten-year period.

Item 18: Pier Protective Granite Panels Repairs

There are granite panels installed on the footings of piers 1 through 20 to help protect the concrete within the tidal zone as well as for aesthetics. The granite panels have scattered cracks, delaminations and up to 4” deep spalls as well as areas of rust staining from the corrosion of the panel anchor bolts. There are also scattered areas of missing or loose lead wool joint material allowing water infiltration between the granite panels and the concrete footings. Repair or replacement of the deteriorated granite panels is anticipated in 2024- 2025.

Item 19: Pile Repairs and Anode Replacement (Main Structure)

The concrete filled steel pipe piles of the main structure piers exhibits scattered areas of a failed coating and isolated areas of corrosion including pitting/section loss of the exterior surface of the steel pipe. Isolated piles of the main structure have an area of 100% section loss in the steel pipe pile, which is exposing the encased concrete. Isolated piers have minor voids between the footing and tremie seal. This item will include steel pipe pile repairs at locations of advanced corrosion and filling of voids along the footings.

Piers 1 through 11 of the main structure have cathodic protection on the exposed concrete filled steel pipe piles. The cathodic protection on the steel pipe piles consists of attached sacrificial aluminum anodes on the exterior of the pile, which corrodes in place of the steel pipe pile. The anodes corrode/deteriorate and will need to be replaced to ensure steel pipe pile corrosion does not initiate.

2020 TEN YEAR RENEWAL AND REPLACEMENT PLAN - NARRATIVE SUMMARY PAGE 41 OF 59 JAMESTOWN VERRAZZANO BRIDGE

There are remnants of a scour monitoring system attached to the base of piers 12 and 13, which was partially removed during the demolition of the original Jamestown Bridge. These remnants will be removed as part of this item.

Item 20: Scour Remediation Study

Scour is the removal of sediment, such as soil, sand and rocks, around the perimeter of the bridge substructures due to the normal movement of water around the obstruction. Severe scour can lead to undermining and weakening of the bridge foundations. Scour is monitored during the routine underwater inspections which are performed every four years. This bridge has a history of scour along the piers, some of which has been mitigated by the normal tidal pattern of Narragansett Bay. This study will examine the current extents of the scour and recommend potential scour repairs and countermeasures, if needed. The study is anticipated in 2026-2027 and will use the findings in the underwater inspection reports as the basis.

Item 21: Security Features – Cameras and ATMS

This item pertains to the installation and future updating of cameras and an ATMS at various locations along the bridge. Cameras and ATMS enhance safety and security by providing RITBA with real time video and data regarding traffic flow, accidents, potential obstructions and unwarranted individuals on the bridge. The 10-Year Plan includes the estimated costs of the initial equipment installation in 2019-2020. Replacement/upgrading of selected components based on usage and technology enhancements is anticipated every three years.

Item 22: Electrical Equipment / Electrical Upgrade

As detailed in Item 24 of the Newport Pell Bridge, safety related lighting must always be properly functioning. There is roadway and navigation lighting on the Jamestown Verrazzano Bridge. Repair, replacement and upgrade of deficient roadway and navigation lighting components are anticipated at a three-year frequency.

Item 23: Signs

The condition of the roadway signage is routinely assessed. As signs deteriorate with age or become damaged, they are replaced and updated to conform to current design standards.

2020 TEN YEAR RENEWAL AND REPLACEMENT PLAN - NARRATIVE SUMMARY PAGE 42 OF 59 JAMESTOWN VERRAZZANO BRIDGE

Item 24: Access Improvement (Main Structure)

Access to the underside of the main structure is currently achieved by an underbridge inspection unit (UBIU), which requires a lane closure on the bridge. As detailed in Item 12 of the Sakonnet River Bridge, RITBA uses short-term rentals when their UBIU is unavailable or multiple UBIUs are required. Use of an UBIU requires a lane closure on the bridge impacting the normal flow of traffic.

Installation of permanent access system will grant constant access to the problematic areas (e.g. interior of the box girder, underside of deck joints, etc.), which need to be maintained throughout the 50 plus year anticipated remaining service life of the bridge. Additionally, a permanent access system will be utilized during bridge inspections, particularly for entering inside the box girders. The access system will consist of fixed ladders from the roadway level that will lead to a limited catwalk system below. The access system will reduce the reliance on access equipment and minimize lanes closures required for underside access, particularly for routine maintenance.

Item 25: West Abutment Area of Original Jamestown Bridge

The land south of the west abutment in North Kingstown has been identified for restoration to its previous natural state or to parkland. The west approach roadway for the original Jamestown Bridge was at this location. This area has been unused since the demolition of the original Jamestown Bridge. Revitalization of this area is anticipated at the end of this ten-year period.

2020 TEN YEAR RENEWAL AND REPLACEMENT PLAN - NARRATIVE SUMMARY PAGE 49 OF 59 RI 138 CONNECTOR HIGHWAY Item 5: Pavement Crack Sealing RI 138 and Frontage Roads

Pavement crack sealing prolongs the service life of roadway pavement by reducing the paths of water infiltration onto the roadway subbase below. Infiltrated water collects on the roadway subbase potentially causing localized erosion and/or settlement. During the winter months, the freeze-thaw action of collected water on the roadway subbase can lead to deterioration (advanced cracking, bituminous break-up, potholes) of the pavement above. A major crack sealing project is anticipated in 2025-2026 and will include a large portion of the RI 138 Connector Highway and the frontage roads.

Item 6: Milling/Paving/ Drainage Repairs RI 138 from RI 1A to Jamestown Verrazzano Bridge

Pavement milling removes the existing pavement in preparation for the new pavement surface. Based on the existing pavement condition, the volume of roadway traffic, quality of the existing subbase below and budget, a determination is made as to the depth of existing pavement to be removed. Anywhere from just enough material to level and prepare the pavement for a new surface, to a full depth removal of the pavement may be required. The amount of existing pavement removal can vary along a segment of roadway based on the existing roadway conditions. An engineering study is the first step in determining the extent of pavement removal required. During the engineering phase, the drainage systems will be evaluated to confirm proper capacity and function. Any modifications to the existing drainage systems will be performed prior to placing the new pavement.

Item 4: Jamestown Administration Building – Rehabilitation/Expansion

The administration building in Jamestown is currently at capacity. The administration building has been expanding to house additional staff and equipment. This item pertains to the potential rehabilitation or expansion of the building required for a future tolling operations call center and other activities, which is anticipated in 2020-2021.

2020 TEN YEAR RENEWAL AND REPLACEMENT PLAN - NARRATIVE SUMMARY PAGE 53 OF 59 POTENTIAL FUTURE ASSETS Item 5: Jamestown Maintenance Building Upgrades

The maintenance building in Jamestown houses selected RITBA owned equipment as well as RITBA’s engineering and maintenance staff. This building underwent renovations between 2016 and 2018 to add office space for RITBA staff and additional space for RITBA owned specialized equipment including the movable barrier machine for the Newport Pell Bridge and an underbridge inspection unit (UBIU) utilized for bridge inspections and repairs. Bathroom, water, sewer, HVAC and office space upgrades for the maintenance building are anticipated in 2020-2021.

Item 6: Jamestown Toll Plaza Tunnel Maintenance and Repairs

There is a tunnel beneath the toll plaza which allows safe passage for RITBA staff to access the eastbound toll booths. The tunnel will require maintenance and repairs during this ten- year period including waterproofing.

Item 7: Jamestown Toll Plaza Upgrades

RITBA is considering an upgrade to the configuration and fare collection process for the Jamestown Toll Plaza. As detailed in Item 12: Realignment of West Approach Roadway in the Newport Pell Bridge Section of this 10-Year Plan, the current lane configuration forces drivers to choose the appropriate lane as they approach the toll plaza, which is particularly problematic for westbound drivers due to the reduced slight distance caused by the roadway alignment. Reconfiguration of the toll plaza lanes and area would be required based on realignment of the approach roadway as well as any upgrades to the fare collection process. The major benefits of the toll plaza upgrades will be improved driver safety, reduced traffic entering/exiting the toll plaza area and efficient toll collection and processing. The 10-Year Plan includes the estimated cost of these improvements in 2022- 2023.

Work under this item will be coordinated with Item 12: Realignment of West Approach Roadway in the Newport Pell Bridge Section and Item 8: Structure “E” Superstructure Replacement and Widening in the Minor Bridges Section of this 10-Year Plan.

Item 8: Jamestown Stormwater Pump Station Building - Miscellaneous Repairs

The Jamestown Stormwater Pump Station is located on Tashtassuc Road near the intersection with North Main Road and was constructed in the early 1990s as part of the RI 138 Connector Highway project. The stormwater pump station was transferred to RITBA in 2013. The 10-Year Plan includes estimated costs for bathroom and septic system installation, and exterior painting in 2021-2022 and 2025-2026. Photo 26 - Jamestown Stormwater Pump Station

Item 9: Dock under Newport Pell Bridge

RITBA plans to install a dock under the Newport Pell Bridge on the Jamestown side. A future RITBA owned boat will be accessed from this dock. The boat will be utilized for bridge inspections, maintenance and safety purposes.

2020 TEN YEAR RENEWAL AND REPLACEMENT PLAN - NARRATIVE SUMMARY PAGE 55 OF 59 POTENTIAL FUTURE ASSETS Item 10: Bristol Historic Administration Building Renovation (Mount Hope House)

The historic Mount Hope House is located on RI 114 in Bristol and consists of two separate buildings – one leased to Roger Williams University and the second building serves as a RITBA maintenance facility. Painting and roofing repairs for the Mount Hope House are anticipated during this ten-year period.

Item 11: Repaving Mount Hope House Parking Lot

The parking area adjacent to the Mount Hope House, and the parking lot on the opposite side of RI 114 will likely require an overlay pavement within this ten-year period.

Item 12: Temporary Storage Building under Mount Hope Bridge (Bristol)

The Mount Hope House garage has limited capacity resulting in RITBA storing equipment in Jamestown and transporting it to the Mount Hope Bridge when needed. RITBA intends to construct a temporary storage building adjacent to the bridge on the Bristol side in 2019-2020.

2020 TEN YEAR RENEWAL AND REPLACEMENT PLAN - NARRATIVE SUMMARY PAGE 56 OF 59 POTENTIAL FUTURE ASSETS Item 13: East Bay Maintenance Facility

The East Bay Maintenance Facility serves as the RIDOT field office for the Sakonnet River Bridge activities including the final demolition of the original bridge. The 10-Year Plan includes the estimated yearly cost of repairs that are beyond general maintenance.

Photo 28 – East Bay Maintenance Facility in Tiverton

Item 14: Sakonnet Pre-Engineered Metal Storage Building (Upper Road Area)

RITBA currently has limited means to store equipment near the Sakonnet River Bridge. RITBA currently stores equipment in Jamestown and transports it to the Sakonnet River Bridge as needed. To store equipment locally, RITBA intends to construct a new non- insulated storage building adjacent to Sakonnet River Bridge in Tiverton. This storage building will have architectural pleasing aesthetics.

2020 TEN YEAR RENEWAL AND REPLACEMENT PLAN - NARRATIVE SUMMARY PAGE 57 OF 59 POTENTIAL FUTURE ASSETS POTENTIAL FUTURE ASSETS

In addition to their owned/controlled assets, RITBA aids in the maintenance of the following RIDOT assets:

• RI 138 on and off ramps to/from RI 238 in Newport • RI 114 approach roadway for the Mount Hope Bridge in Bristol • Detention basin southwest of the Hummocks Avenue Bridge in Portsmouth

Conanicus Avenue and East Shore Road in Jamestown are currently owned by RIDOT. Preliminary discussions have occurred regarding the transferring of a portion of these roadways to RITBA’s jurisdiction. The limits of this potential transfer would be East Shore Road from the RI 138 westbound on and off ramps to the intersection with Conanicus Avenue, and Conanicus Avenue from the intersection with East Shore Road to the RI 138 eastbound on and off ramps located northwest of the toll plaza. Conanicus Avenue and East Shore Road within this region are in poor condition with heavy wear, previous patches and extensive map cracking/break-up of the pavement. The concrete curbs exhibit spalling throughout and isolated areas of settlement. A significant improvement project is needed for these roadways consisting of milling and paving as well as curb, median, guardrail and drainage repairs.

The 10-Year Plan does not include maintenance and repair costs for potential future assets.
