Major U.S. 422 Construction Continues, Caution Advised for Commuters

Traffic, flagging

LOWER POTTSGROVE, PA — The Pennsylvania Department of Transportation (PennDOT) has announced that the extensive construction work on U.S. 422 and Porter Road in Lower Pottsgrove Township, Montgomery County will continue into next week. The $83.6 million project aims to reconstruct and improve approximately 1.7 miles of the expressway and replace two bridges between the Sanatoga Interchange and Porter Road.

From Monday, January 15, through Thursday, January 18, commuters should anticipate single lane closures in both directions on U.S. 422 and reduced lanes on Porter Road during specific hours. The closures are necessary for clearing and grubbing operations, along with barrier installation on the eastbound lane.

Given the scale of the construction, motorists are urged to allow extra time for their journeys as backups and delays are expected. PennDOT has emphasized that all scheduled activities are weather-dependent and therefore subject to change.

The project aims to extend the design life and improve the ride quality and safety of U.S. 422. It will also address the poor condition of roadside elements such as stormwater basins, drainage inlets, slope stabilization, guiderails, and signs.

The Section M1B project involves reconstructing U.S. 422 on both existing and revised alignments to enhance travel and safety. This includes improving horizontal curve radii, shoulder widths, and 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. The bridge over Sanatoga Road and Sanatoga Creek will also be reconstructed and widened.

Further improvements include lengthening the acceleration ramp from the Sanatoga Interchange to westbound U.S. 422, installing Intelligent Transportation System equipment, constructing sound barriers along portions of westbound U.S. 422, upgrading signage, replacing the drainage system and cross culverts, and enhancing stormwater management facilities.

The Section M1B project is the seventh to proceed under PennDOT’s initiative to rebuild and improve the U.S. 422 Bypass near Pottstown. Since 2012, PennDOT has invested more than $260 million in improving the U.S. 422 corridor in Montgomery and Chester counties.
