Four weekends. This accounts for the time taken to completely replace the structurally deficient Route 581 Bridge over 10th Street. For this project TPD worked with contractor J.D. Eckman, Inc. to deliver the project via design-build. The original three-span superstructure was built in 1985 and is a mainline interstate highway bridge.

The heavily traveled state route filters motorists into and out of Harrisburg and carries approximately 86,000 vehicles per day. Due to its high importance, TPD knew our team had to come up with a solution that would dramatically reduce impacts to the surrounding areas, while continuing to allow traffic to pass to and from the State’s capitol. An accelerated design-build replacement was the only solution we knew would fit the bill. Per Leslie Richards, PennDOT Secretary, this solution ended up “saving motorists roughly a year and a half of full-time traffic disruptions.”

TPD’s structural design services included the design of precast steel beam/concrete deck sections constructed off-site, just a short distance away. These sections were transported and erected into place and completed with accelerated closure pours and latex modified concrete overlay finishing. Traffic control design included development of directional interstate weekend closures, including detour signage, in-depth community outreach, and development of an Incident Management Plan. This complex accelerated bridge replacement was completed over various weekends in June/July 2015.
