LOWER POTTSGROVE TOWNSHIP, PA — The Pennsylvania Department of Transportation (PennDOT) will initiate construction activities next week on an $83.6 million project to reconstruct and improve approximately 1.7 miles of U.S. 422 and replace two bridges in Lower Pottsgrove Township, Montgomery County.
The project aims to extend the design life, enhance ride quality and safety of the expressway, and improve roadside elements in poor condition, including stormwater basins, drainage inlets, slope stabilization, guiderail, and signs.
U.S. 422 will be reconstructed on both existing and revised alignments to improve horizontal curve radii, shoulder widths, and vertical clearance. The culvert at Sprogels Run and the single-span bridge carrying U.S. 422 over Porter Road will be removed and replaced with a new two-span bridge. The bridge over Sanatoga Road and Sanatoga Creek will also be reconstructed and widened.
Additional improvements include:
- Reconstructing and lengthening the acceleration ramp from the Sanatoga Interchange to westbound U.S. 422
- Installing Intelligent Transportation System equipment along the U.S. 422 corridor
- Constructing sound barriers along portions of westbound U.S. 422
- Upgrading and installing new signage
- Replacing the closed system drainage system and cross culverts
- Improving stormwater management facilities, including two extended detention basins
Beginning Monday, November 20, and Tuesday, November 21, slow-moving shoulder closures will be in place on U.S. 422 between Evergreen Road and Armand Hammer Boulevard. Westbound lanes will be affected from 7:00 AM to 2:00 PM, and eastbound lanes from 9:00 AM to 5:00 PM.
Surveying crews will lay out the work area features, including road construction sign placements and work zone limits, in preparation for early-stage construction set to commence after the Thanksgiving Day Holiday.
Motorists are advised to allow extra time when traveling through the work areas due to potential backups and delays. All scheduled activities are weather dependent.
The general contractor for this project is J.D. Eckman, Inc. of Atglen, PA. The project is financed with 100 percent federal funds, and work on the entire project is expected to finish in late 2028.
