The Center City project area extends 6,120 feet from Arch Street, near 30th Street, east to the CSX Railroad bridge, near the University Avenue Exit.

PennDOT continues to revise the 2020 work schedule for this project as the region deals with the impacts of the COVID-19 Pandemic. Details will be posted here each week in a Travel Advisory for the following week’s construction schedule.

The bridge in Conshohocken, Montgomery County, (above) carries the Schuylkill Expressway/I-76 over Route 23/Conshohocken State Road and is located just east of the Conshohocken/I-476 interchanges. Several other I-76 bridges in Montgomery County also will be repaired in 2020.

The Schuylkill Expressway/I-76 is the Philadelphia region’s major east-west expressway, connecting commuters from the western suburbs and South Jersey with Center City Philadelphia, the University City area, the Sports Complex, several area hospitals and all points in between.

Under this project (SR 76, Section SRE), PennDOT is repairing the long, deteriorated viaduct that carries  the Schuylkill Expressway/I-76 along the west bank of the Schuylkill River  in Center City Philadelphia. A smaller bridge on the expressway near Conshohocken, in Montgomery County, also will be repaired, as will several other structures in Montgomery County.

Work has resumed on this project, one of Pennsylvania’s critical infrastructure projects as designated by Gov. Tom Wolf. All of the restarted projects will follow mandated protocols for worker/social distancing, health monitoring and personal protection.

With this project, PennDOT is extending the life of the structures by:

  • Repairing the decks’ expansion joints; 
  • Repairing deteriorated sections of the concrete decks;
  • Repairing components of the sub-structures;
  • Repairing the viaducts’ drainage systems; and
  • Repaving the Center City viaduct with a concrete overlay.

The repairs also require overnight lane restrictions at both locations, plus temporary ramp closures and a limited number of weekend full closures of the eastbound or westbound Center City structure…Read more,

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.

Grays Ferry Bridge

The Pennsylvania Department of Transportation is investing $13.3 million to repair and rehabilitate the deteriorated superstructure of the Grays Ferry Avenue bridge over the Schuylkill River, AMTRAK and CSX rail lines. The bridge is situated between 34th Street and Woodland Avenue in Philadelphia.

U.S. 1

The Pennsylvania Department of Transportation is investing almost $90 million to rehabilitate the 2,589-foot long U.S. 1/Roosevelt Expressway viaduct between the Broad Street and Wissahickon Avenue/Germantown Avenue exits in the Nicetown section of Philadelphia.
