Roadway, Bridge Construction Continues Next Week on U.S. 422 in Lower Pottsgrove Township


King of Prussia, PA – The Pennsylvania Department of Transportation (PennDOT) announced today that construction activities are planned next week on U.S. 422 under an $83.6 million project to reconstruct and improve approximately 2.1 miles of the expressway and replace bridges between the Sanatoga Interchange and Porter Road in Lower Pottsgrove Township, Montgomery County.

Motorists are advised of the following travel restrictions:

The stoppages and paces are required for the protection of motorists and workers so crews can safely perform controlled rock blasting to excavate the area for drainage construction.

Motorists are advised to allow extra time when traveling through the work areas because backups and delays will occur. All scheduled activities are weather dependent.

Under this Section M1B project, U.S. 422 will be reconstructed on both existing and revised alignments to improve horizontal curve radii, shoulder widths, and vertical clearance to enhance travel and safety. A culvert at Sprogels Run, located just east of Porter Road, along with an existing single-span bridge carrying U.S. 422 over Porter Road, will be removed and replaced with a new two-span bridge. The bridge carrying U.S. 422 over Sanatoga Road and Sanatoga Creek will also be reconstructed and widened.

For more information on this project and PennDOT's U.S. 422 reconstruction program, visit the U.S. 422 projects page.

Motorists can check conditions on major roadways by visiting 511PA, which is free and available 24 hours a day, provides traffic delay warnings, weather forecasts, traffic speed information, and access to more than 1,000 traffic cameras. 511PA is also available through a smartphone application for iPhone and Android devices, by calling 5-1-1, or by following regional X alerts.
