Major reconstruction is planned for a four-mile stretch of the Pennsylvania Turnpike in Chester County. Work will take place at Milepost 320-324, within Tredyffrin Township, and represents one of the PA Turnpike’s most complex projects to date.
Comprehensive Roadwork Planned
The project, anticipated to be completed in the summer of 2031, will involve a complete rebuild of the roadway, adding a travel lane in each direction. Shoulder and median widths will also be increased. Three mainline bridges over local roads will be replaced, and culverts will be lengthened to improve stormwater drainage.
Work began the week of January 19 with tree removal and utility relocation. Full construction is scheduled to begin this spring. Initial phases will involve shifting traffic toward the median to allow for work on the outer lanes. Crews will focus on demolishing and rebuilding roadbeds and bridges while prioritizing safety for both workers and drivers.
Funding and Scope
The approximately $338 million project is fully funded by toll dollars and is part of the PA Turnpike Commission’s 10-year Capital Plan. H&K Group, Inc. was awarded the contract in December. The PA Turnpike supported over $737 million in construction bids in 2025 to modernize and improve the customer experience.
Brad Heigel, the PA Turnpike’s Chief Engineer, stated that the project “enhances roadway safety, improves customer experience and demonstrates our commitment to maintaining a reliable transit corridor across the Commonwealth.”
