VIADUCT REHABILITATION COMPLETED

PennDOT’s $47.1 million project to repair and rehabilitate two I-76 (Schuylkill Expressway) viaducts in Center City Philadelphia, along with several other smaller structures in Montgomery County, was completed in July 2021 after two-plus years of construction.

This project repaired or replaced the Center City viaduct’s sub-structure components, drainage system, and the concrete deck’s expansion joints. The contractor also resurfaced the viaduct’s concrete deck, using fast-curing PPC (Polyester Polymer Concrete) that minimized the need for long-term lane closures.

All traffic restrictions that were in place due to this project are now lifted.

Thank you for your interest and your patience during this important project that will help keep one of Philadelphia’s busiest highways structurally sound and safer for years to come.

Chestnut Street Bridges

PennDOT is rehabilitating, repairing and repainting the steel superstructure and replacing the deck of the Chestnut Street bridge over the Schuylkill River that connects Center City Philadelphia with University City and West Philadelphia. The $103,589,847 project also will replace the decks of three adjacent Chestnut Street bridges, two viaducts on Schuylkill Avenue and two ramp structures for I-76 .

PennDOT is in the midst of a long-term, multi-phase initiative to rebuild and improve Interstate 95 in Pennsylvania. Five major projects to reconstruct the I-95 between the Interstate 676 and Cottman Avenue interchanges in Philadelphia are in various stages of design or construction, including active projects at the Girard Avenue, Allegheny Avenue and Betsy Ross/Bridge Street interchanges. Construction also is underway on the Adams Avenue Connector.
