Thomas Road Reopens After Four-Month Shutdown in Tredyffrin

TREDYFFRIN, PA —Thomas Road, between Walker and Richards roads, reopened this week, after being closed for four months as part of an ongoing $117.8 million project to upgrade the Pennsylvania Turnpike.

Thomas Road underpass has been closed since early October for the demolition of the existing overpass and the construction of abutments and the foundation for the new bridge.

Updating the bridges over Thomas and Glenhardie roads is part of the project to widen a two-mile stretch of the turnpike to six lanes at the Valley Forge Interchange.

Turnpike officials said that the two-mile stretch is the most widely traveled section of the turnpike.

Thomas Road was used regularly by locals and as a cut-through for residents in the Phoenixville area driving to King of Prussia and Tredyffrin Township.

Thomas Road reopened in mid-winter, just as predicted by turnpike officials.

Project status

The project is expected to be completed in 2025.

Temporary traffic lights have been installed on Thomas Road and Glenhardie Roads to allow single traffic through the roads during the construction project.

Excavation for sediment basins on the eastbound side of the Turnpike near the Valley Forge Service Plaza is ongoing.

On the eastbound side, drilling and grouting for ground improvement are ongoing, along with access and haul road construction.

On the westbound side, drainage pipe installation continues along with drilling and grouting for ground improvement.
