Traffic Alert

Pennsylvania’s Department of Transportation, PennDOT, announced that construction to resurface northbound Interstate 476 at the MacDade Boulevard Interchange in Ridley Township, Delaware County will be underway from Monday, May 15th to Friday, May 19th. Alternating lane closures are scheduled from 8:00 PM to 5:00 AM the following morning. Given the ongoing construction, commuters should allocate extra time for potential backups and delays in the area. As with all construction, the schedule is dependent on weather conditions.

This PennDOT contract includes several road improvements, such as:

  • Adding a left turn lane on eastbound MacDade Boulevard at the Bullens Lane Intersection to improve safety and sight lines.
  • Modernizing traffic signals and curb ramps to meet ADA requirements.
  • Installing dynamic message boards and CCTV cameras to improve connectivity.
  • Widening and realigning the westbound ramp from northbound I-476 to MacDade Boulevard.
  • Constructing auxiliary lanes to relieve traffic congestion.

Additionally, a new pedestrian bridge will be constructed adjacent to MacDade Boulevard.

Allan Myers, LP from Worcester, Montgomery County, is supervising a $16.2 million project aimed at enhancing the safety and efficiency of MacDade Boulevard and the interchange with northbound I-476. The project is being financed with 80% federal funds and 20% state funds, and is scheduled to be completed by summer of 2026.
