Nighttime Milling and Paving on I-476 to Cause Traffic Delays

Traffic Alert

SOUTHEASTERN PENNSYLVANIA — The Pennsylvania Department of Transportation (PennDOT) announced that nighttime milling and paving operations will begin next week on Interstate 476. This is part of a $63.7 million project to resurface, repair, and improve nearly 17 miles of the interstate, including on-and-off ramps and bridges, stretching from I-76 in West Conshohocken Borough, Montgomery County, to I-95 in Ridley Township, Delaware County.

Motorists should prepare for the following travel restrictions:

  • From Tuesday, May 28, through Friday, May 31, lane closures will occur on sections of southbound I-476 between the U.S. 1 and I-95 interchanges from 8:00 PM to 5:00 AM the following morning for milling, paving, and guiderail replacement.
  • During the same dates and times, lane closures will also be in place on sections of southbound I-476 between the I-76 and Route 3 (Upper Darby/Broomall) interchanges for similar work.
  • Additionally, from 8:00 PM to 5:00 AM, lane closures will affect sections of northbound I-476 between the I-95 and Route 3 (Upper Darby/Broomall) interchanges for guiderail replacement.
  • From Wednesday, May 29, through Friday, May 31, Bryn Mawr Avenue will be reduced to a single lane with flagging at the Ithan Avenue intersection in Radnor Township for bridge repair from 9:00 AM to 3:00 PM.

Motorists are advised to allow extra time when traveling through these areas as traffic backups and delays may occur. All scheduled activities are weather dependent.

This extensive project aims to extend the design life of the interstate, enhance ride quality and safety, and improve the condition of roadside elements such as stormwater basins and drainage inlets. PennDOT’s contractor will mill and overlay travel lanes and shoulders in both directions, repair 49 structures, improve 21 stormwater management basins, repair sound walls, replace inlets at select locations, and install new pavement markings, delineators, rumble strips, signage, and guiderail.
