LOWER POTTSGROVE TWP, PA — The Pennsylvania Department of Transportation (PennDOT) has scheduled a crucial traffic shift on eastbound U.S. 422 to commence on Thursday, September 26, marking the initiation of Stage 2 construction under a significant $83.6 million project. This endeavor aims to rebuild and enhance approximately 2.1 miles of the expressway and replace key bridges between the Sanatoga Interchange and Porter Road in Lower Pottsgrove Township, Montgomery County.
To accommodate this work, a single lane pattern will be implemented on eastbound U.S. 422 from Sunday, September 22, through Wednesday, September 25, between 5:00 PM and 5:00 AM for paving operations. On Thursday, September 26, a similar lane restriction will occur from 9:00 AM to 5:00 AM the following day for the traffic shift. Additionally, intermittent single lane closures will affect westbound U.S. 422 from Evergreen Road to Armand Hammer Boulevard from September 23 to September 27, between 4:00 AM and 2:00 PM for roadway reconstruction.
Drivers are urged to plan for extended travel times due to expected delays and backups. These activities are contingent upon weather conditions. Upon the completion of Stage 2 in late 2025, eastbound traffic will transition to the newly constructed pavement, allowing the commencement of westbound reconstruction in Stage 3.
This Section M1B project will involve reconstructing U.S. 422 along both existing and modified alignments to improve safety and travel conditions. Enhancements will include better horizontal curves, expanded shoulder widths, and increased vertical clearance. A culvert at Sprogels Run and an existing single-span bridge over Porter Road will be replaced with a new two-span bridge, while the bridge over Sanatoga Road and Sanatoga Creek will be rebuilt and widened.
