The presentation will feature both the design and construction engineering challenges and solutions that were developed. Abstract: The SB I-95 to EB SR-202 Interchange Flyover Bridge is part of a design-build project in Jacksonville, FL to redesign the traffic interchange at I-95 and SR-202. The interchange handles heavy traffic volume and was in need of a significant upgrade. The flyover bridge utilizes precast elements in several innovative ways to provide a signature structure while aiding constructability on a tight job site. The new flyover bridge is a curved seven span structure on an 1100ft radius. It is composed of two units with expansion joints at each abutment and at interior Pier 5. Two lines of curved precast U-girders, post- tensioned for continuity, support the superstructure. The substructure consists of six single column piers with two CIP and four precast pier caps. The precast caps are designed to support the girders during construction at jobsite locations with no room for falsework. Each unit has significant sections that are constructed over traffic which utilize straddle frames and strong back supports from cantilevered girders during erection. The design of the superstructure was significantly impacted by the construction methods and tight clearance requirements necessary to accommodate maintenance of traffic. The paper will describe the innovative design features and unique challenges solved during design and construction of this bridge. Notes: The seven span flyover bridge to be described in this paper is the first curved, precast U girder bridge constructed for the Florida DOT. The bridge uses spliced construction and a number of innovative design features to accommodate a number of challengin Co-Author's Andrew Mish Summit Engineering Group / Modjeski and Masters 10822 West Toller Drive Littleton CO 80127 303-933-9114 [email protected] IBC 2017 Conference - Individual Abstract Submission Abstract #: 17-51 Date Received 9/28/2016 Score: Name: William Castle Company: W.J.

Technology is ever changing and we need to take advantage of it. This presentation will detail traditional underwater inspection and scanning sonar imaging and highlight the importance and potential for both. Abstract: This presentation details the benefits of scanning sonar imaging in relation to underwater inspections. Standard underwater inspection and scanning sonar inspection are clearly defined highlighting the key components of each. Comparisons between the two types of inspections are made including; methodology of inspection, inspection requirements, challenges encountered, and final outputs. A case study of a railroad bridge located in Delair, New Jersey is provided highlighting the differences between a standard underwater inspection and scanning sonar inspection. This case study will document the comparison of the sonar system and traditional underwater inspection findings and evaluate the feasibility and potential for both. The conclusions are then summarized, reiterating the benefits of using the new technology for the marine field.

Even small projects and structures can teach you new things. Issues encountered and lessons learned are highlighted and can be beneficial for both consultants and contractors of pre-fabricated bridges. Abstract: This presentation illustrates the issues encountered and lessons learned for the design/build of small to medium pre-fabricated bridges. Three case studies are used to highlight methodologies, constructability, and issues encountered during the projects. The three bridges were owned and contracted by; a county, a company, and a government agency respectively. The proposed usage and restriction of each proposed bridge differed. Sometimes it takes experience to learn the easiest and more efficient methodology of replacing a structure.

Digital image analysis software is now available commercially for bridge engineers and is likely to become increasingly important over the next several years. This study will benefit IBC attendees because it will expose the audience to these emerging technologies for the non-destructive evaluation of steel bridge components. The audience will gain insight into the capabilities-and limitations-of these techniques, as well as potential applications for their future use for bridge inspection and load rating. Abstract: A major aspect of bridge deterioration derives from corrosion of steel components and reinforcement. Current practices for quantifying corrosion rely on estimating the net section loss of steel members and applying an average section loss reduction to a component. This process neglects the existence of stress concentrations caused by localized corrosion and pitting, a phenomena that can reduce the ultimate capacity and ductility of a component. This paper reports on the development of a nondestructive evaluation technique for corroded steel using digital imaging and 3-D optical measurement techniques. The goal is to provide better analytical models for quantifying the impact of localized corrosion defects on steel component load capacity. Weathering steel specimens with severe pitting, extracted from a decommissioned bridge, were first measured and evaluated using conventional methods. Tensile testing in conjunction with digital image correlation then provided results that were used to calibrate an imaging technique that quantifies pitted regions and provides a capacity evaluation. Comparisons of the two evaluation methods indicate that the non-contact imaging technique more accurately represented the true load capacity of the specimens, and that the technique has potential for use by inspectors in the field. Future work includes field testing to explore the practical challenges of the inspection environment.

Listeners will take away unique experiences in pedestrian bridge design in the use of steel castings and pedestrian induced vibrations analysis per SETRA. Abstract: The Longfellow Bridge Rehabilitation Project is a Design-Build project, undertaking the rehabilitation of a century old multi-span steel arch structure and its iconic “salt and pepper shaker” towers. Within the same project, sitting in the shadows of the Longfellow, sits a nondescript and inadequate pedestrian bridge, soon to be replaced with the Fanny Appleton Pedestrian Bridge, named after Longfellow’s wife. The Appleton, a 750 foot long structure, with 550 feet of elevated bridge including 222 foot main span which
