About 18,700 cars a day cross the bridge, built in 1957.
The work is part of a $103.6 million project that also will affect two Schuylkill Avenue crossings over I-76, the I-76 west ramp to Chestnut Street, the Walnut Street ramp to I-76 east, and the stone arch bridges on Chestnut Street over 24th Street and freight train tracks. Portions of walls along the river also will be repaired. The prime contractor on the project is Buckley & Company Inc. of Philadelphia.
Eastbound traffic will be routed onto either 38th Street, 36th Street, or 33rd Street to Market Street, then to 23rd Street. Drivers also can turn onto Schuylkill Avenue from 30th Street. Cyclists can follow the same detours as cars, or can travel on 38th Street or 34th Street south, left onto Spruce Street, then cross the river at South Street. People on foot will be routed to Market or Walnut Streets.
Motorists can check conditions on more than 40,000 roadway miles by visiting www.511PA.com or downloading the 511PA application for iPhone and Android devices. 511PA, which is free and available 24 hours a day, provides traffic delay warnings, weather forecasts, traffic speed information, and access to more than 950 traffic cameras.
