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.
