PennDOT to Begin Construction on I-476 for Traffic Safety Systems

Road construction

SOUTHEASTERN PENNSYLVANIA — The Pennsylvania Department of Transportation (PennDOT) announced that construction will commence on Monday, June 10, on a $10.4 million project aimed at improving traffic safety and managing congestion on Interstate 476 in Delaware and Montgomery counties.

The project will span approximately 14.5 miles of I-476, integrating Variable Speed Limit (VSL) and Queue Warning (QW) systems. These systems will help manage traffic flow and enhance safety by providing real-time speed adjustments and warning messages based on current road conditions.

Under this initiative, PennDOT will install Intelligent Transportation System (ITS) conduits, queue detectors, variable speed limit signs, dynamic message signs, and the necessary technology to operate these systems from PennDOT’s new Regional Transportation Management Center (RTMC).

The VSL systems will display varying speed limits depending on real-time expressway conditions, traffic, and weather. This will help improve traffic flow and safety by notifying drivers of changing travel conditions. Meanwhile, the QW systems will alert motorists of significant slowdowns ahead, reducing the risk of sudden stops and rear-end collisions.

The project covers I-476 South from about 1.8 miles north of the U.S. 30 Interchange (Exit 13) to I-95 and I-476 North from I-95 to Marple Road near the Route 3 Interchange (Exit 9). Motorists should expect weekday shoulder closures from 9:00 AM to 3:00 PM on sections of both northbound and southbound I-476 for various construction activities.

Drivers are advised to allow extra time when traveling through these work zones, as traffic backups and delays may occur. All scheduled activities depend on weather conditions.
