Nighttime Construction on I-476 to Cause Delays in Delaware and Montgomery Counties

Road construction

SOUTHEASTERN PENNSYLVANIA — Motorists should prepare for nighttime lane closures on Interstate 476 this weekend into early next week, as PennDOT advances on two projects aimed at bolstering travel and safety across sections in Delaware and Montgomery counties.

From Sunday, June 30, through Tuesday, July 2, from 8:00 PM to 5:00 AM, drivers will encounter lane restrictions on northbound and southbound I-476. The affected stretch, spanning from the I-76 (Philadelphia/Valley Forge) interchange to the Route 3 (West Chester Pike) interchange, traverses West Conshohocken Borough and Lower Merion Township in Montgomery County, as well as Radnor, Haverford, and Marple townships in Delaware County. The closures facilitate guiderail and pavement repairs.

Additionally, on Tuesday, July 2, a lane closure is slated for northbound I-476 at the MacDade Boulevard Interchange in Ridley Township, Delaware County, from 8:00 PM to 5:00 AM. This operation is for the installation of Intelligent Transportation Systems (ITS).

Anticipate significant traffic backups and delays when traveling through these areas. The scheduled work is contingent upon weather conditions.

The ongoing guiderail and pavement repairs are part of a comprehensive $63.7 million initiative to resurface and enhance nearly 17 miles of I-476. Meanwhile, the ITS installation at the northbound I-476 and MacDade Boulevard Interchange belongs to a separate $16.2 million project designed to improve travel and safety on MacDade Boulevard and at the interchange itself in Ridley Township, Delaware County.

Drivers are advised to allow extra time for travel and to remain vigilant while navigating through the construction zones.
