Nighttime Construction on I-476 to Cause Delays Next Week

Lane Closure - Traffic Alert

SOUTHEASTERN PENNSYLVANIA — The Pennsylvania Department of Transportation (PennDOT) announced that nighttime construction on Interstate 476 will occur next week as part of a $63.7 million project to improve nearly 17 miles of the roadway. This extensive project aims to resurface, repair, and enhance the interstate from I-76 in West Conshohocken Borough, Montgomery County to I-95 in Ridley Township, Delaware County.

From Sunday, June 9, through Friday, June 14, lane closures will be in effect from 8:00 PM to 5:00 AM on sections of both northbound and southbound I-476 between the U.S. 1 and I-95 interchanges. The work will involve milling, paving, and guiderail replacement.

Motorists should allow extra time when traveling through these areas as backups and delays are expected. All scheduled activities depend on weather conditions.

Under this project, PennDOT’s contractor will mill and overlay travel lanes and shoulders in both directions. The work also includes repairs on 49 structures, improvements to 21 stormwater management basins, rock slope stabilization, sound wall repairs, and replacements of inlets at select locations. Additionally, new pavement markings, delineators, rumble strips, signage, and guiderails will be installed.

The goal of this project is to extend the design life of I-476, improve ride quality and safety, and enhance roadside elements in poor condition. H&K Group, Inc. of Skippack, PA, is the general contractor, and federal dollars fully fund the project. Completion is expected in late 2025.
