PennDOT to Begin U.S. 422 Reconstruction, Improvement Project in Lower Pottsgrove Township

The Pennsylvania Department of Transportation (PennDOT) announced today that construction activities will begin next week begin next week on an $83.6 million contract to reconstruct and improve approximately 1.7 miles of U.S. 422 and replace two bridges between the Sanatoga Interchange and Porter Road in Lower Pottsgrove Township, Montgomery County.

The purpose of this project is to extend the design life and improve ride quality and safety of the expressway and improve the current condition of roadside elements such as stormwater basins, drainage inlets, slope stabilization, guiderail and signs that are in poor condition.

Under this improvement 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.

Additional improvements under this project include:

  • Reconstructing and lengthening the acceleration ramp from the Sanatoga Interchange (Township Line Road) to westbound U.S. 422;
  • Installing Intelligent Transportation System (ITS) equipment and components along the U.S. 422 corridor and on arterial roadways;
  • Constructing sound barriers along portions of westbound U.S. 422;
  • Upgrading existing signage and installing new signage;
  • Replacing the closed system drainage system and cross culverts throughout the project limits; and
  • Improving stormwater management facilities, including two extended detention basins.

Beginning Monday, November 20, and Tuesday, November 21, a slow-moving shoulder closure will be in place on U.S. 422 between Evergreen Road and Armand Hammer Boulevard in the westbound direction from 7:00 AM to 2:00 PM, and in the eastbound direction from 9:00 AM to 5:00 PM.

Surveying crews will be laying out the features of the work area, including locations for the placement of road construction signs and the limits of the work zone, in advance of the placement of construction barrier and other early-stage construction that is scheduled to get underway after the Thanksgiving Day Holiday.

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

J.D. Eckman, Inc. of Atglen, Pa, is the general contractor on this project, which is financed with 100 percent federal funds. Work on the entire project is expected to finish in late 2028.

This U.S. 422 construction contract is the seventh project in PennDOT's initiative to rebuild and improve the U.S. 422 Bypass near Pottstown. Since 2012, PennDOT has completed six projects, valued at $263.4 million, to improve the U.S. 422 corridor in Montgomery and Chester counties.
