King of Prussia, PA – A traffic pattern change with accompanying lane restrictions will start Friday morning, October 23, on the Benjamin Franklin Parkway between 21st Street and 20th Street in Philadelphia for the replacement of the bridge carrying 20th Street and the Parkway over Interstate 676, the Pennsylvania Department of Transportation said today.
Crews will replace the 20th
Street/Parkway bridge in three construction stages through July 2017.
This structure, which is 96 feet long and 517 feet wide, is one of seven
structurally deficient bridges over I-676 that PennDOT is replacing as
part of a $64.8 million transportation improvement project that began in
The new construction traffic pattern, which
is scheduled to be in place by 5:00 AM Friday and continue until July
2016, will reduce the Parkway’s eastbound inner lanes from three lanes to two approaching 21st Street, and shift the two eastbound through lanes to the right onto temporary pavement to merge with Winter Street approaching the 20th Street intersection.
Three eastbound lanes will continue across 20th Street onto Logan Circle.
Westbound traffic will have two lanes coming from Logan Circle onto the Parkway at 20th Street. Motorists will follow the temporary construction traffic pattern to return to the Parkway’s westbound inner lanes where a third lane returns at 21st Street. The Parkway’s westbound outer lanes will remain open and unchanged.

The speed limit on the Parkway through the temporary construction traffic pattern will be 15 miles per hour.
In addition, motorists traveling north on 20th Street will experience a slight shift in the travel lanes when driving through the intersection with the Parkway.
The schedule for implementing the temporary construction traffic pattern is weather dependent.
The Parkway’s eastbound outer lanes remain closed at 21st Street. Motorists continue to be detoured over 21st Street and Winter Street.
The bridges carrying 20th Street/Parkway, 19th Street, and pedestrian walkways at the Free Library and former Family Court building are the first four of seven structures to be replaced under this project. PennDOT also will replace the deteriorating bridges carrying 22nd Street, 21st Street, and 18th Street.
The seven bridges over I-676 are being replaced in two major stages to minimize traffic impacts. The entire project is scheduled to finish in fall 2019.
