I-76 West Closed at Night, I-76 East Closed Next Weekend for Viaduct Construction in Center City Philadelphia


King of Prussia, PA – Travel restrictions will be in place next week on Interstate 76 between the 30th Street and South Street exits in Philadelphia, including a westbound lane closure weeknights and a complete eastbound closure next weekend for repairs and repaving of two Center City viaducts, the Pennsylvania Department of Transportation (PennDOT) announced today. 

Eastbound I-76 will be closed continuously and detoured between the 30th Street and South Street interchanges from 11:00 PM Friday, September 13, to 5:00 AM Monday, September 16, for pavement repairs and resurfacing. 

Prior to the weekend closure, on Monday, September 9, through Thursday, September 12, westbound I-76 will be reduced to a single lane at 9:00 PM, then closed completely from 11:00 PM to 5:00 AM the following morning between the 30th Street and Interstate 676 interchanges for painting and demolition of the Schuylkill Avenue viaduct over I-76. During the closure, westbound I-76 motorists will exit at 30th Street and follow Schuylkill Avenue to the ramp to westbound I-76 or to eastbound I-676.

In addition to the full directional closures, single lane restrictions also will be in place on I-76 next week between 30th Street and South Street:

  • Monday, September 9. through Wednesday, September 11, from 9:00 PM to 5:00 AM the following morning, and Friday, September 13, from 9:00 PM to 11:00 PM, eastbound I-76 will be reduced to a single lane for construction activities to prepare for the full weekend closure; and
  • Monday, September 9, through Friday, September 13, from 9:30 AM to 3:00 PM, there will be periodic, short-term closures of the right deceleration lane on westbound I-76 approaching the ramp to 30th Street for concrete placement under the viaduct.

During next weekend’s closure of eastbound I-76, motorists will be directed to use the following alternate routes:

  • Follow eastbound Interstate 676 to southbound Interstate 95 to access I-76; or
  • Exit at 30th Street, follow 30th Street around the station, turn right on Market Street, left on 38th Street and straight on University Avenue to 34th Street to access the ramp to eastbound I-76.

During the closure of eastbound I-76, the following ramps will be closed and detoured from 11:00 PM Friday, September 13, to 5:00 AM Monday, September 16:

  • Westbound I-676 ramp to eastbound I-76. During the closure, I-676 motorists will be detoured west on I-76 to the Montgomery Drive/West River Drive exit, then take the ramp to eastbound I-76 and follow the detour at 30th Street; and
  • Walnut Street ramp to eastbound I-76. Motorists will be directed to follow Walnut Street, turn left on 38th Street and go straight on University Avenue to 34th Street and the ramp to eastbound I-76.

Motorists are advised that the paving schedule may change based on weather forecasts because the paving material being used on the I-76 viaduct is a synthetic concrete (Polyester Polymer Concrete) that must be applied under dry conditions. The PPC material is being used because the synthetic concrete cures faster, allowing the viaduct’s surface to be rehabilitated while minimizing the need for long-term lane closures that are required for curing conventional concrete pavement.

Drivers are advised to use an alternate route or allow extra time when traveling through the work areas during the lane closures because significant backups and delays will occur. 

PennDOT is repairing and resurfacing the I-76 viaduct under a $39.8 million contract that also includes repairs to the three-span I-76 structure over Route 23 (Conshohocken State Road) in West Conshohocken Borough, just east of the Interstate 476/Conshohocken Interchange in Montgomery County.

Repairs to the Schuylkill Avenue viaduct are part of PennDOT’s $103.6 million project to rehabilitate the Chestnut Street bridge over the Schuylkill River — which is scheduled to close for one year beginning in mid-June — and eight other nearby structures, including those carrying Schuylkill Avenue over I-76 between Walnut Street and Chestnut Street, and between Chestnut Street and Market Street.
