Chestnut Street Bridges


I-76 Overnight Lane and Ramp Closures June 18-21 near 30th Street

King of Prussia, PA – Overnight lane and ramp restrictions will be in place on Interstate 76 near 30th Street in Philadelphia for construction on the viaduct carrying Schuylkill Avenue over the expressway between Walnut Street and Market Street and on the ramp from westbound I-76 to 30th Street, the Pennsylvania Department of Transportation (PennDOT) announced today. 

On Monday, June 18, through Thursday, June 21, from 9:00 PM to 5:00 AM the following morning, I-76 will be reduced to a single lane in both directions between the South Street and Interstate 676 interchanges.   
In addition, the ramp from westbound I-76 to 30th Street will close on Monday, June 18, through Thursday, June 21, from 9:00 PM to 5:00 AM the following morning for repairs. Motorists normally using this ramp will be detoured west on I-76, east on I-676, exit at 23rd Street, left on 22rd Street, left on the ramp to westbound I-676, and east on I-76 to the ramp to 30th Street. 

Motorists are advised to use an alternate route or allow additional time for travel on I-76 through the work areas because backups and delays will occur. All scheduled activities are subject to change depending on weather conditions. 

Construction crews on the $103.6 million project are repairing or replacing the viaduct’s deteriorated steel deck beams and cross members and the ramp’s expansion dams and concrete pavement.   

PennDOT is rehabilitating the Chestnut Street bridge over the Schuylkill River and seven other nearby structures, including those carrying Schuylkill Avenue over I-76 between Walnut Street and Chestnut Street, and between Chestnut Street and Market Street.

In addition to repairing and repainting the steel superstructure and replacing the deck of the main bridge carrying Chestnut Street over the Schuylkill River and the two Schuylkill Avenue structures over I-76, the project also includes:

  • Rehabilitating two structures on the Interstate 76 on-and-off-ramps between Chestnut Street and Walnut Street;
  • Resurfacing Chestnut Street from 31st Street to 30th Street, and from 24th Street to 23rd Street;
  • Constructing wider sidewalks and installing decorative barrier and railings on the Chestnut Street and Schuylkill Avenue bridges;
  • Rehabilitating a 900-foot section of the river wall structure between I-76 and the Schuylkill River from Market Street and Walnut Street;
  • Rehabilitating a 15-foot section of the retaining wall supporting the Schuylkill River Trail under Chestnut Street;
  • Installing new traffic signals, Intelligent Transportation System (ITS) equipment, and street lighting along Chestnut Street between 31st Street and 23rd Street;
  • Replacing millennium lighting on Chestnut Street over the Schuylkill River;
  • Constructing a new trellis at the Chestnut Street Trailhead to the Schuylkill River Trail;
  • Restriping pavement markings for a bicycle lane on Chestnut Street between 34th Street and 22nd Street; and
  • Installing a new clear acrylic barrier along Amtrak Northeast Corridor tracks located on the west side of Schuylkill Avenue between Chestnut Street and Walnut Street.

The bridges on Chestnut Street and Schuylkill Avenue will be under construction concurrently and will remain open for most of the project. There will be various lane and sidewalk restrictions during the three stages of construction that will require shifts in travel lane and sidewalk configurations.

Approximately midway through the project beginning in mid-2019, a detour will be in place for about one year on Chestnut Street from Schuylkill Avenue to 23rd Street for the rehabilitation of the structurally deficient bridge carrying Chestnut Street over the CSX rail lines. 

The Schuylkill River Trail will be closed below Chestnut Street for approximately three months over the winter of 2018-2019 for repairs. 

In addition, the on-and-off-ramps at the I-76 Interchange between Chestnut Street and Walnut Street will be restricted to a single lane of traffic during construction. There will also be nighttime and weekend full closures of the ramps during certain construction operations.

The entire project is scheduled to finish in fall 2020. 

Buckley & Company Inc., of Philadelphia is the general contractor on the project, which is financed with 80 percent federal and 20 percent state funds.
