Major PA Turnpike Project Underway In Tredyffrin

TREDYFFRIN TOWNSHIP, PA — The Pennsylvania Turnpike is ready to begin one of its most complex projects to date, and the project is in Tredyffrin Township.

Crews will begin the total reconstruction and widening at Milepost 320-324, a four-mile stretch in Tredyffrin, this week.

Workers are now working to remove trees along the turnpike’s right of way and relocating utilities. Construction on the project will begin in the spring.

In the early phase of total reconstruction, traffic shifts inward to the median, allowing work on outer lanes. This involves setting up barriers and signage for safety. Crews then will demolish and rebuild outer lanes, including roadbeds and bridges, while ensuring minimal ecological impact and maintaining traffic flow.

The roughly $338-million project, fully funded by toll dollars as part of the PA Turnpike Commission’s 10-year Capital Plan, was awarded to H&K Group, Inc. in December.

In addition to roadway widening, the project also replaces three mainline bridges over local roads, lengthens culverts and improves stormwater draining throughout the area.

Work is anticipated to be complete in summer 2031.

"For more than 85 years, customers have relied on the Pennsylvania Turnpike to get safely to their destinations," Brad Heigel, the PA Turnpike’s Chief Engineer, said. "This project enhances roadway safety, improves customer experience and demonstrates our commitment to maintaining a reliable transit corridor across the Commonwealth."

Started in 1999, the Pennsylvania Turnpike’s Total Reconstruction Initiative rebuilds the road from the ground up, adds another travel lane in each direction and increases shoulder and median width to support safety, reduce traffic queuing and enhance emergency responder access.

To date, 174 miles of PA Turnpike mainline have undergone Total Reconstruction.
