Construction Continues Next Week on U.S. 422 Improvement Project in Lower Pottsgrove Township

02/08/2024

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

Motorists are advised of the following travel restrictions:

  • Monday, February 12, through Thursday, February 15, from 4:00 AM to 2:00 PM, a single lane closure will be in place on westbound U.S. 422 between Evergreen Road and Armand Hammer Boulevard for bridge and drainage construction.
  • Monday, February 12, through Thursday, February 15, from 9:00 AM to 6:00 PM, a single lane closure will be in place on eastbound U.S. 422 between Armand Hammer Boulevard and Evergreen Road for bridge and drainage construction.
  • Monday, February 12, through Thursday, February 15, from 7:00 AM to 5:00 PM, an intermittent single lane flagging pattern will be in place on Porter Road between High Street and Sanatoga Station Road for clearing and grubbing.
  • Monday, February 12, through Thursday, February 15, from 7:00 AM to 5:00 PM, an intermittent single lane flagging pattern will be in place on Sanatoga Road between Linfield Road and East High Street for clearing and grubbing.

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.

The purpose of this project is to extend the design life and improve ride quality and safety of the U.S. 422 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 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.

Additional improvements 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.
  • Improving stormwater management facilities, including two extended detention basins.

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