TRANSPORTATION MANAGEMENT PLAN WIN 19270.00 I-95 Portsmouth-Kittery Piscataqua River Bridge

Executive Summary The I-95 Portsmouth-Kittery Piscataqua River Bridge project will conduct critical maintenance on this large and important bridge and prepare the bridge and approaches for future part-time shoulder use for improved traffic capacity. The corridor carries more than 40,000 vehicles per day in each direction, and a much higher number during the summer weekends. The existing I-95 corridor is above capacity and construction of this project, while important, will cause additional traffic disruption. The goal of this Transportation Management Plan (TMP) is to evaluate the existing site conditions and provide mitigation strategies to accomplish this critical project with a minimum of safety, access, and mobility disruption. This project entails comprehensive repairs to the existing bridge deck, replacement of the wearing surface, replacement of all bridge rails with safer concrete barriers, replacement of the lighting system, and numerous other improvements. It also includes widening of the Maine approach up to Exit 3 northbound and up to Exit 2 southbound. This approach work will prepare the roadway for implementation of part-time shoulder use (allowing traffic to travel on the shoulder as a fourth lane) from Exit 7 in New Hampshire to Exit 3 northbound and Exit 2 southbound in Maine. A future project will add the ITS and remaining elements necessary to operate the Part-Time Use Shoulder. Traffic through the corridor is highly seasonal and varies significantly weekly. Summer traffic (in particular Friday Northbound and Sunday Southbound) already sees significant delays. Friday Northbound traffic and Sunday Southbound traffic exceeds the capacity of two lanes year-round. Certain elements of work will require traffic to be reduced to one lane—this can only be accomplished without severe traffic disruption during the night. This TMP includes a three-pronged approach to addressing traffic concerns on this project: 1. Traffic Control Plans (TCP) are included in the contract documents and provide an approach to phasing this project to provide a minimum of safety, access, and mobility disruption while still providing adequate time and access for the Contractor to accomplish the work. 2. Transportation Operations (TO) provide strategies to address ongoing traffic concerns at the project site while the project is ongoing. 3. Public Outreach (PO) serves to alert the public of the project and will assist in alleviating both traffic congestion and frustration within the adjacent communities by providing up-to-date information and guidance about work-zone conditions.

Introduction The goal of this Transportation Management Plan (TMP) is to document strategies for the I-95 Portsmouth-Kittery Piscataqua River Bridge project and surrounding area to best maintain traffic flow, public involvement, and safety through advance warning and prior planning. The plan will utilize a combination of Traffic Control Plans (TCP), Public Outreach (PO), and Transportation Operations strategies (TO).

Project Background Information Project Summary The I-95 Piscataqua River Bridge connecting New Hampshire and Maine is a 4,503-foot steel through-truss bridge, 98 feet wide, providing six lanes of traffic over the Piscataqua River that carries approximately 40,000 vehicles in each direction daily. Construction of the bridge began in 1968 and the bridge was officially opened to traffic in 1972. The purpose of this project is to conduct critical maintenance on the I-95 Piscataqua River Bridge connection between Maine and New Hampshire. Completion of this project will extend the life of the bridge and help ensure a continued safe crossing for commercial vehicles, commuters, and vacationers between New Hampshire and Maine. In addition, work will be done to prepare the corridor for future part-time shoulder use for increased traffic capacity. Project scope of the repairs includes deck repair, overhang replacement, median replacement, barrier replacement, joint replacement, and a variety of other miscellaneous work, both above and below the deck. In addition, the Maine I-95 approach will be prepared for future part-time shoulder use for additional traffic capacity. This work includes shoulder reconstruction and widening, addition of a concrete median barrier, and miscellaneous work, extending to the Rt. 236 bridge. Finally, the entire corridor from Exit 7 in Portsmouth, New Hampshire to Exit 3 in Kittery, Maine will be overlaid and striped to provide a clean final surface. The project will be constructed from 2019 to 2022, with the substantial completion date (when all work except the final overlay and striping is to be completed) set as October 1, 2021. Affected Roadways • I-95 between Exit 7 in Portsmouth, New Hampshire and Exit 2/3 in Kittery, Maine (direct construction). The Maine approach roadway from the bridge to the end of the project is part of the Maine Turnpike. • Route 1 Bypass/Sarah Mildred Long Bridge (traffic will detour to this location) • Exit 7/Market Street (there will be a ramp closure and traffic will detour when the ramp is not closed as well, changing traffic patterns at this location) • Exit 1/Dennett Road (there will be NB snd SB ramp closures)

Construction will begin in the spring of 2019. Numerous phases will be required to repair the full width of the bridge deck, which is 98’-0” wide, while minimizing traffic disruption. For this reason, the project duration will be quite long. The project substantial completion date is scheduled for October 1, 2021. Substantial completion requires all work to be complete and traffic control removed, except for final paving and striping. The final paving and striping are to be completed by the contract completion date, which is May 20, 2022. The general sequence of work envisioned on the project is to construct the southbound outside portion of the project, then the northbound outside portion of the project, and then finally the median. This allows the existing open rails to be replaced with solid concrete barriers before traffic is shifted close to them; it also allows additional roadway width on the Maine approach to be constructed before moving traffic into that area. In addition, the Woodbury Ave. bridge project, listed above, adds significant traffic to the northbound portion of the U.S. Rt 1 Bypass, so it makes sense to allow that project to complete before beginning work Northbound on I-95. Throughout the duration of the project, lane closure times have been optimized to keep traffic disruption to a minimum. Certain seasons and days have more restrictions; these add to the overall duration of the project.

TMP Background and Development Because the I-95 Piscataqua River Bridge serves as a major thoroughfare for people in multiple states and combines multiple state agencies, this Transportation Management Plan (TMP) was established. The plan serves as a living document that implements strategies to aide in the maintenance of safety and mobility in the study area and aides through coordination of the large number of stakeholders for this project. Federal Highway Association (FHWA) sets forth requirements for this plan in the Work Zone Safety and Mobility Rule (the Rule) . NHDOT has also developed Policy #601.01, Guidelines for Implementation of the

7 | P a g e

TRANSPORTATION MANAGEMENT PLAN WIN 19270.00 I-95 Portsmouth-Kittery Piscataqua River Bridge

Work Zone Safety and Mobility Policy dated October 12, 2007. Both of these documents were used as the basis for this report. It should be noted that an evaluation of criteria was performed by NHDOT to determine if the project is deemed significant. According to a Memorandum dated July 27, 2016, the project is classified as significant and thus the TMP reflects this. TMP Development The TMP began in the preliminary engineering stage and is a living document that evolves throughout design and construction of the project. Early stages outline strategies that lay the foundation for design and development continues through the construction process and finally once the project has been completed, for review and analysis to be used on future projects. The five stages are outlined below: • Existing Conditions: In this early stage existing conditions and information required is gathered, issues and concerns affecting construction and the finished product are gathered and established, TMP Strategies are established, and the project’s Significance is determined. • Draft TMP Development: During this stage of development the effects of the work zone are established, stake holders are identified, draft TCP are created, and TMP strategies are coordinated. This was accomplished during the PDR process. • Final TMP: During this stage of development the TMP is finalized, TCP are finalized for bid purposes, special provisions and contract documents are established. This was accomplished during PS&E of the project. • Implement, Monitor and Revise: As TMP strategies that must be implemented by the Contractor prior to the start of construction, Resident will review traffic operations, as well as maintain a traffic control checklist and work zone traffic crash report. A Traffic Coordinator is designated by the Contractor to oversee plan implementation, and the MaineDOT Area Construction Engineer, NHDOT District Construction Engineer (DCE) and MTA Project Contact are informed of any notable changes to the TMP. • Evaluation: Evaluate TMP: Individual TMP strategies and the overall TMP performance are evaluated. The NHDOT performs a "lessons learned" evaluation that includes recommendations for improvements on the TMP process. Finally, evaluation reports are compiled by the DCE and Bureau of Turnpikes that are given to the TCC for review. TMP Approval Process In coordination with NHDOT and the MTA, MaineDOT has been working with T.Y. Lin International (TYLI) in the TMP development. As components of design become refined, TYLI will meet with MaineDOT, MTA, and NHDOT for approval of details on a case-by-case basis. Final TMP will be approved upon acceptance of the final PS&E package by MaineDOT, MTA, and NHDOT.

Existing and Future Conditions

Existing and Future Roadway Characteristics The I-95 Bridge over the Piscataqua is a 6-lane divided North-South highway with three lanes in each direction. The bridge is 98 feet in width and the posted speed limit northbound is 55 mph and southbound is 65 mph. There are exit ramps on the northerly and southerly ends of the bridge. To the south, the Exit 7 On and Off ramps connect travelers to downtown Portsmouth, New Hampshire via Market Street. To the north, Exit 1 On and Off ramps connect travelers to Kittery, Maine via Dennett Road. Final configuration of the bridge is anticipated to include three 11.5-foot lanes in each direction with a wide overhang shoulder 12.5 foot in width for Part-Time Shoulder Use and a median shoulder 2 to 3 feet in width. The bridge will have ITS devices to indicate if lanes are open for Part-Time Shoulder Use and exits may close seasonally to assist with this. This work is being accomplished via a separate contract. Existing Traffic Data Existing AADT on the bridge is currently approximately 40,000 VPD in each direction. The table below provides the average AADTs for 2014 – 2017 (the latest full years collected by the MaineDOT WIM Station). It should be noted that the new Memorial Bridge was opened to traffic in 2013 and that the Sarah Mildred Long Bridge was closed to traffic in August 2016 and reopened to traffic in March 2018.

These results are considered to be a ‘worst case scenario’. With an estimated 23% less traffic due to the opening of Sarah Mildred Long Bridge and natural diversion of traffic, the longer duration of the closure, and having a better-informed public, these delays are anticipated to be reduced. Operationally, aside from peak seasonal periods, the bridge operates acceptably. During peak seasonal periods volume exceeds available capacity. This is caused both by geometric constraints on the bridge itself, and by nearby ramps. Work Zone Traffic Volumes Traffic volumes used for assessing and developing Traffic Control Plans and Specifications for this project were developed using 2017 volumes and 1.5% traffic growth. A 23% diversion rate was assumed, accounting for the opening of the Sarah Mildred Long US 1 Bypass bridge adjacent to the site and natural diversion due to work zone congestion, public outreach, and real-time travel time signage. The Maine Turnpike Authority provided comprehensive hour-by-hour volumes across this site, which allowed detailed projections of traffic volumes to be developed. These served as basis for the limitations on Contractor operations and lane closures that were developed. They also provide a basis for assessing likely delays and public outreach needs.

Work Zone Impacts Assessment This bridge is an extremely important transportation link between Maine and New Hampshire, and serves as Maine’s primary corridor to the rest of the nation. As discussed before, traffic volumes are quite high on this corridor—significant delays already exist during peak summer weekends. However, the Contractor will need access to all portions of the bridge deck for a significant amount of time to complete the required work. Detour routes are limited and unable to handle the volume of traffic carried by this bridge. Through the preliminary and final design processes, and based upon input from stakeholders and traffic analysis, a general approach was determined: keep lanes open when traffic demands are high and allow lanes to be shut when traffic demands are lighter . Moderate traffic delays will be tolerated throughout the construction project. However, the contract will include incentives to encourage the Contractor to maintain 3 lanes open whenever possible during periods of likely delays. This approach will lead to a long construction duration and increased project cost since work will be done in many phases and will require many night-time lane closures. However, the project team felt this was the best balance for this project, given the critical importance of maintaining traffic volumes through this corridor.

Transportation Management Plan Strategies The purpose of work zone impact management strateg ies is to minimize traffic delays , improve safe ty for both work ers and th e trav eling public , and maintain access for loc al businesses and residents. These strategies have been divided int o three broad groups: • Traffic Contro l Plans (TCP) • Transportation Operations Strategies (TO) • Public Outreach Strategies ( PO)

Traffic Control Plans (TCP) General Traffic Control Scheme Under construction, three lanes are to be maintained during the peak summer months. However, traffic capacity will still be reduced during that time versus existing conditions due to the construction activities, reduced lane widths, and the lack of a shoulder. During the peak traffic season, traffic may be reduced to 2 or 1 lane during the night only. During the lower traffic season, permanent reduction to 2 lanes of traffic will be allowed, with reduction to 1 lane allowed during the night. For specific additional dates and times (every Friday Northbound and every Sunday Southbound, for instance) incentives will be paid to the Contractor to have 3 lanes open in a given direction. The most significant delays are expected during weekend periods just outside of the peak summer months, but these are anticipated to be less than the test closure due to the longer duration of the closure and the opening of the Sarah Mildred Long Bridge as an alternative crossing between Maine and New Hampshire. Contract documents prescribing this approach are divided into two components: Traffic Control Plans and Traffic Control Specifications. Traffic Control Plans A detailed set of Traffic Control Plans have been developed for the project that meet MUTCD standards. A set of the plans is included in the Appendix. Six long-term roadway configuration phases have been developed. A summary of key elements of the Plans is provided below. Pre-Phase 1 • Install all PCMS • Close Exit 1 southbound entrance ramp Phase 1 • Use merging taper southbound to reduce to two lanes through work zone • Shift southbound traffic towards existing center median barrier on Piscataqua River Bridge • Contractor to work on outside shoulder and lane southbound

TRANSPORTATION MANAGEMENT PLAN WIN 19270.00 I-95 Portsmouth-Kittery Piscataqua River Bridge

Traffic signal timings at the Market Street/Albacore Park Connector and Albacore Park Connector/Route 1 Bypass intersections will be adjusted to reflect detour volume changes. Work Zone Safety Management Strategies The primary purpose of these strategies is to optimize the traffic safety concerns through the work zone and include : Traffic Coordinator The Contractor shall assign a Traffic Coordinator to the Project who shall coordinate all traffic control on the Project and work with the Project Superintendent and MaineDOT Resident Engineer to ensure safe and efficient set up, maintenance and removal of the traffic control layouts and devices for the duration of the project. The Traffic Coordinator duties shall include, but are not limited to: • Developing in conjunction with the Project Superintendent a traffic control program for the day’s work activities which will facilitate traffic in a safe and efficient manner. • Ensuring all traffic control implements (signs, arrow boards, barrels, portable changeable message signs, concrete barrier, work zone crash cushions, etc.) are on-site or readily available, and required subcontractors are available, so the traffic program can be implemented effectively. • Directing the safe and effective set up and removal of all signing implements to least impact the traveling motorist. • Reviewing and understanding the Project maintenance of traffic plans. • Demonstrating a working knowledge of construction signing and traffic control requirements in conformance with the latest issued Manual on Uniform Traffic Control Devices. • The Contractor shall supplement the traffic control plan with a daily plan, which includes schedules for utilizing traffic coordinators and flaggers on local roads. This plan shall be submitted daily and agreed upon cooperatively with the Resident. Speed Reduction Message Signs A reduced speed limit will be utili zed on I-95. The speed will be temporarily reduced from 65 MPH to 55 MPH southbound and 55 MPH northbound for all construction phases. This will be done to improv e traffic safety in the work zone and to help protect workers. Moveable Temporary Concrete Barrier The work shall consist of furnishing, installing, operating, maintaining, disassembling, and final removal of moveable temporary concrete barrier Temporary Traffic Barrier: The project will utilize temporary concrete barrier to protect the construction operations and the traveling public .

23 | P a g e

TRANSPORTATION MANAGEMENT PLAN WIN 19270.00 I-95 Portsmouth-Kittery Piscataqua River Bridge

Crash Cushions The project will utilize crash cushions to protect the ends of temporary concrete barriers and other fixed objects as defined by FHWA's Roadside Design Guide. TMP Monitor I In spect ion Team The Contractor shall provide full time Traffic Monitor(s) to the Project who shall continuously observe and patrol the traffic setups to ensure traffic is flowing as anticipated, and all traffic control devices (PCMS, signs, arrow boards, drums, cones, Type III barrier, etc.) are in the correct locations and functioning properly. The Traffic Monitor(s) shall provide at least hourly monitoring (24-hours/seven days a week) when Project traffic control devices are in place (including non-work hours) to monitor and report traffic issues and to advise the Traffic Coordinator of damaged, displaced or non-functioning traffic control devices (arrow boards, portable changeable message signs, barrels, signs, etc.). The Traffic Monitor shall report any and all disabled motorists, accidents or other unusual occurrences to 911 as applicable, to the appropriate (NH or MTA) TMC, and to the Resident or his representative, throughout the duration of any and all lane closures. The Traffic Monitor shall once daily inspect the Contractor’s traffic control on the local roads in Kittery and Portsmouth to ensure the correct signs and portable changeable message signs, are in place, are not damaged or disturbed, and/or are operating properly. Traffic / Incident Management and Enforcement Strategies The primary purpose of these strategies is to manage traffic operations through the work zone and includes : Maine Service Patrol (Dispatched by MTA TMC) From the first weekend in April, through the first weekend in December (35 weeks) the MTA will operate Service Patrol vehicles between the Piscataqua River Bridge (mile 0.1) and Wells (mile 19) or to Kennebunk (mile 25) on Fridays, Saturdays, Sundays and Holidays listed below from 11:00AM to 7:00PM. (Dates and times are subject to change.) AutoBase will provide Service Patrol vehicles, including all equipment, supplies, and trained personnel, to perform the below defined services with the ultimate objective of promoting safety on the Turnpike, congestion relief, and highway assistance to motorists and their vehicles. Such services include: • Providing motorists with light service (fuel stalls, flat tires, jump starts, overheats, etc.) • Coordinating for a tow, if necessary • Providing emergency transportation off the highway, as needed • Traffic control for disabled vehicles and minor crashes • Removal of debris and hazards from the Turnpike • In patrol areas without sufficient shoulder, relocation of disabled vehicles to designated areas.

24 | P a g e

TRANSPORTATION MANAGEMENT PLAN WIN 19270.00 I-95 Portsmouth-Kittery Piscataqua River Bridge

New Hampshire Service Patrol (Dispatched by NH TMC) NHDOT will operate Service Patrol vehicles between the Massachusetts State Line and the Maine State Line according to the following schedules. (Dates and times are subject to change.) From the week before Memorial Day weekend to the week after Labor Day weekend (Summer Patrol):

• Monday through Thursday 5:30 AM to 8:00 AM and 3:30 PM to 6:00 PM • Friday 5:30 AM to 8:00 AM and 12:00 PM to 7:00 PM • Saturday 9:00AM to 5:00 PM • Sunday 10:00 AM to 6:00 PM From the week after Labor Day weekend to the week before Memorial Day weekend (Winter Patrol):

• Monday thru Friday 5:30 AM to 8:00 AM and 3:30 PM to 6:00 PM • No patrol on Saturdays or Sundays Transportation Management Centers NHDOT, MTA and MaineDOT maintain Transportation Management Centers that will monitor traffic through this project, as well as all other active projects in the area . Mile Post Markers The statewide mile marker system will be maintained on I-95 to identify the location of an incident that occurs within the work zone. Coordination with Media MaineDOT will provide press releases to the media concerning the project when important milestones are achieved and when traffic patterns will be changed. Press releases will be coordinated between the 3 agencies prior to release. Increased Penalties for Work Zone Violations Signs are included in the sign package on the approaches to the work zone warning the motorists that ME/NH Law doubles the penalty for fines in work zones.

Public Outreach Strategies (PO) The PO component of a TMP consists of strategies that address communication with the public and concerned stakeholders, before and during the project. This component may include public awareness strategies and motorist information strategies, such as brochures, websites, radio, VMS messages, pre- trip and in-route information, etc. Public communication is an integral tool in keeping the general public, area residents, businesses, and appropriate public entities aware of what is happening in the area. To do this, a Public Outreach Campaign (POC) has been created to help alleviate the sustained impact on safety and mobility in the project area during construction. The POC has the potential to reduce work zone impacts by providing

25 | P a g e

TRANSPORTATION MANAGEMENT PLAN WIN 19270.00 I-95 Portsmouth-Kittery Piscataqua River Bridge

specific information concerning the project to the traveling public and community and alert them of potential impacts and available alternatives to avoid these impacts. The MaineDOT is implementing a POC to help mitigate many of these issues by alerting drivers of upcoming work zones and providing information such as potential delays and detours. This information allows drivers, and other interested parties, to make informed decisions about the route to take and when to travel. The POC can be broken into the following two categories: Public Awareness and Motorist Information. Each of these categories is expanded upon in the next few pages. Public Awareness MaineDOT and MTA are working jointly to develop a public awareness campaign for this project and the nearby York Toll Plaza project. Communication Objectives: • Generate awareness of all the projects along this corridor. • Notify motorists of the key milestones of the work and how the project milestones might affect traffic flow. • Inform local communities of work activity and how it might impact first responders, schools etc. • Clarify project benefits to encourage patience with all the work activity. Benefits include necessary modernization of infrastructure and safety enhancements, as well as greater efficiency and ultimately less congestion for motorists. Targeted Audiences: • Local community influencers and residents • Motorists/Toll payers traveling between New Hampshire and Maine • Trucking firms • General public • Elected officials Methods to Deliver Message: • A brand name, logo and tagline to put all the work under one umbrella project. This includes the nearby York Toll Plaza project as well, since it is a major concurrent effort. • A branded website with email alerts . This one-stop shopping website will have all the information about both projects including maps, schedules, photography of current activity, press releases, Q & A, and more. • Social media sites with real-time updates about traffic and project schedules. Twitter is used by the agencies to send out information using the following accounts: o https://twitter.com/maineturnpike (15,200 followers) o https://twitter.com/NewHampshireDOT (8,300 followers) o https://twitter.com/NHDOTi95 (3,900 followers) o https://twitter.com/MaineDOT1 (7,000 followers)

26 | P a g e

TRANSPORTATION MANAGEMENT PLAN WIN 19270.00 I-95 Portsmouth-Kittery Piscataqua River Bridge

Facebook is also used by the agencies to send out information: o https://www.facebook.com/MaineTurnpikeAuthority (17,800 followers) o https://www.facebook.com/MaineDOT (19,800 followers) o https://www.facebook.com/NHDOT (35,300 followers) • Real time travel alerts . Information is provided to the public on a regional basis through the New England Compass website ( http://www.newengland511.org/ ). Project-specific information will be provided to the appropriate TMC by the Contractor for input to the New England Compass system, as appropriate. • Media Relations – press conferences to announce the collaboration, announce the start of work, end of project etc. and routine press releases about work activity. Coordinate media requests for information and pitch story to relevant media outlets. Newspaper articles are already being written about the project, and the Agencies will support Newspaper articles with appropriate information for public distribution. • Community Relations – Work with community leaders and perhaps form stakeholders’ groups to keep an ear to the ground about brewing issues. Coordinate community requests such as speakers at civic groups or outreach to schools. As the projects end, organize celebratory events. • Marketing – Radio, print and social media ads for significant milestones such as exits closing, lane reductions and especially project launches or completions. The three agencies will have their media relations departments in close coordination to avoid confusion. Motorist Information Similar to above, there are various methods to reach the motorist about project work zone activities. The biggest difference is that this information is current and/or real-time information. The following list is a summary of the strategies . Portable Changeable Message Sign (PCMS) These portable signs will be used to provide real time information about work activities, lane or ramp closures, slowed or stopped traffic, and potential for alternative routes. Portable Changeable Message Signs will be placed at the following key locations: • I-95 Southbound north of Exit 2 • Route 1 Southbound prior to Route 1 Bypass • Route 236 Eastbound west of I-95 • Route 236 Westbound east of I-95 • State Road Eastbound prior to Bolt Hill Road • Walker Street Westbound prior to Route 1 • Market Street Westbound prior to Albacore Park Connector • Route 1 Bypass Northbound prior to Portsmouth Circle • Route 4 Eastbound prior to Woodbury Avenue • I-95 Northbound

27 | P a g e

TRANSPORTATION MANAGEMENT PLAN WIN 19270.00 I-95 Portsmouth-Kittery Piscataqua River Bridge

Work Zone Safety Highway Signs: Traditional ground mounted signs are also another method of providing static information to the traveling public. These signs also provide information to visitors of the area who may be unfamiliar and may want to avoid the work zone. These signs will be used on the approaches to the work zone to help increase the drivers' awareness. A sign package will be included in the contract plans. Examples of signs include roadwork ahead, lane shift ahead, ramp closed, and work zone speeding fines. Permanent Dynamic Message Signs MTA and NHDOT maintain dynamic message signs that may be used to supplement the PCMS. NHDOT, MTA and MaineDOT TMC Coordination The Traffic Management Centers monitor traffic conditions through this corridor to provide real-time information and enhance the ability to react to traffic and other roadway conditions, thus improving the flow of traffic. The TMCs have direct lines of communication with the State Police, with the other TMCs, and with other emergency responders, facilitating response to incidents or other situations that affect the State roads. Close coordination with the TMCs will help manage and disseminate road user information. Project Resident, State Police, and emergency responder coordination with the TMCs on a regular basis will help maintain traffic flow through the use of DMS and also inform motorists of work zone incidents. The TMCs are a vital component in the Public Outreach (PO) and Transportation Operations (TO) strategies.

Traffic Control Monitoring Standard work zone inspections, monitoring, and review procedures will be followed for this project throughout construction. During the course of construction, inspections will be the responsibility of the contractor's Traffic Coordinator, the MaineDOT Resident and supporting construction oversight team, and the Agencies. They will be observing traffic conditions and making recommendations concerning any changes that need to be made with respect to traffic management. The inspections may utilize the Traffic Control Checklist provided in Appendix D of NHDOT's Guidelines for Implementation of the Work Zone Safety and Mobility Policy. Traffic control concerns will be discussed during the regular construction meetings for this project. The Resident must approve TCP revisions proposed by the Contractor prior to implementation. During the implementation of a new traffic pattern the contractor's Traffic Coordinator, the MaineDOT construction oversight team, and the Agency Transportation Management Centers will monitor the effectiveness of the TCP and advanced notification procedures. This will be used to track the performance of the TMP, adjust as appropriate, and to be able to periodically update the Agencies on its effectiveness. These monitoring efforts will include the following: • Visually monitoring TCP performance (i.e. queue lengths, crashes, complaints, travel times, etc.) • Accident Rates: Compare to baseline rates before construction • Feedback from the Public Outreach efforts

28 | P a g e

TRANSPORTATION MANAGEMENT PLAN WIN 19270.00 I-95 Portsmouth-Kittery Piscataqua River Bridge

• Project Team updates: As part of the regular construction meetings, the TMP will be a reoccurring agenda item regarding status and effectiveness. At the completion of the contract, the Resident will prepare and submit to the Agencies a TMP Evaluation Report as discussed in Section 2.b.iv. Developing and Implementing Transportation Management Plans, Step 12, of NHDOT's Guidelines for Implementation of the Work Zone Safety and Mobility Policy.

Implementation Costs The Maintenance of Traffic costs from the bid submitted by SPS New England, the low bidder, were about $8,800,000. In addition to those costs are costs separately funded by the agencies, including media outreach costs (around $135,000 each for MaineDOT and MTA) and a State Police budget of $1,000,000.
