MARPLE TWP, PA — Drivers traveling along Route 3 (West Chester Pike) in Delaware County should prepare for significant overnight delays through November 9 as construction continues near the Interstate 476 interchange. Weeknight lane closures will affect both directions of the highway between Lawrence Road and the I-476 ramps in Marple and Haverford townships.
At a Glance
- Roads Affected: Route 3 (West Chester Pike) eastbound and westbound between Lawrence Road and the I-476 ramps
- Dates: Weeknights through Monday, November 9, 2026
- Times: 7:00 PM to 5:00 AM the following morning
- Reason: Road construction and interchange traffic-flow improvements
The Pennsylvania Department of Transportation (PennDOT) warns that significant backups and delays may occur during the overnight restrictions. All scheduled work is weather dependent.
The lane closures are part of a $5.2 million project designed to reduce congestion and improve traffic movement through the Route 3 and I-476 interchange.
Under the project, the westbound Route 3 ramp leading to northbound I-476 will be separated from the traffic signal at South Lawrence Road, allowing vehicles to enter the ramp without stopping for that signal.
Crews will also restripe the northbound I-476 entrance ramp to accommodate the revised traffic pattern.
South Lawrence Road will retain its existing lane configuration, including two left-turn lanes and one right-turn-only lane.
Drivers should plan extra travel time, watch for changing traffic conditions, and consider alternate routes when possible during overnight construction.
