Philadelphia Bridge Replacement Project Completed
The seven bridges over I-676 were rebuilt in two major stages to minimize traffic impacts. The original two-span bridges, which were constructed in the late 1950s, all were replaced with single-span structures that do not require a center pier in the middle of I-676.
State and local officials including PennDOT Secretary Leslie S. Richards marked the completion of a major improvement project to replace seven bridges and enhance public spaces over Interstate 676 in downtown Philadelphia on Oct. 26. "Finishing this project a year ahead of the original schedule speaks to the cooperative working relationship that PennDOT and its engineering and construction teams enjoyed with city administrations, the Parkway Council Foundation, and the residents of Parkway neighborhoods," said Richards. "The improvements made here strengthen our transportation infrastructure and add to the welcoming atmosphere of this beautiful Parkway area."
Work began in early 2015 on the $64.8 million project. PennDOT replaced the expansive structure at 20th Street and the Benjamin Franklin Parkway, as well as other deteriorating bridges that carry 22nd Street, 21st Street, 19th Street, and 18th Street over I-676. Two pedestrian bridges over I-676 connecting Logan Circle with the Free Library, between 20th and 19th streets, and with the former Family Court building, between 19th and 18th streets, also were replaced.
PennDOT also upgraded the pedestrian spaces adjacent to the bridges and along the parkway and improved several pedestrian crossings at intersections along the project corridor.
The seven bridges over I-676 were rebuilt in two major stages to minimize traffic impacts. The original two-span bridges, which were constructed in the late 1950s, all were replaced with single-span structures that do not require a center pier in the middle of I-676. Five bridges are owned by the City of Philadelphia and two by the state. I-676 also was resurfaced between 18th and 22nd streets and new lighting was installed on the undersides of the bridges.
Buckley & Company, Inc. of Philadelphia is the general contractor on the project, which is financed with 100 percent federal funds. The preliminary engineering, final design and other pre-construction costs were funded with federal and state dollars.
