Nighttime Roadwork on I-476 Expected to Cause Traffic Delays

Traffic Alert

SOUTHEASTERN PENNSYLVANIA — The Pennsylvania Department of Transportation (PennDOT) has embarked on a comprehensive $63.7 million resurfacing and repair project along Interstate 476. Spanning nearly 17 miles from West Conshohocken Borough, Montgomery County, to Ridley Township, Delaware County, the initiative promises significant improvements but also anticipates short-term traffic disruptions.

Scheduled from Monday, May 6, through Friday, May 10, motorists traveling I-476 can expect lane closures affecting both northbound and southbound travel. Specifically, sections of the northbound lane between the Route 3 (Upper Darby/Broomall) and I-76 (Philadelphia/Valley Forge) interchanges will see restrictions for milling and paving operations from 8:00 PM to 5:00 AM. Concurrently, southbound sections between the U.S. 1 and I-95 interchanges will undergo similar work within the same hours.

Additionally, daytime work on Darby Road in Haverford Township will necessitate a reduction to a single lane with flagging between Route 320 (Sproul Road) and Radnor Road for bridge repair. This is scheduled from 9:00 AM to 3:00 PM, from Monday, May 6, through Friday, May 10.

PennDOT advises drivers to plan for extra travel time through these areas, as the construction activities are likely to cause backups and delays. The timing of these operations is contingent upon favorable weather conditions.

The scope of the project is extensive, encompassing not only the milling and overlay of I-476’s travel lanes and shoulders but also the repair of 49 structures and the enhancement of 21 stormwater management basins. Additionally, crews will address rock slope stabilization issues, repair existing sound walls, and replace inlets in selected locations. New pavement markings, delineators, rumble strips, signage, and guiderails are also part of the planned improvements.

This ambitious undertaking aims to extend the design life of the interstate, elevate ride quality, and bolster safety measures. It also focuses on refurbishing roadside elements like stormwater basins, drainage inlets, slope stabilization, and signage, many of which are currently in poor condition.

H&K Group, Inc., based in Skippack, PA, has been contracted to carry out this federally funded project, slated for completion in late 2025.
