Excavation, Drainage Installation Planned Next Week on U.S. 422 in Lower Pottsgrove Township


King of Prussia, PA - The Pennsylvania Department of Transportation (PennDOT) announced today that excavation and drainage installation operations will occur next week on U.S. 422 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, March 4, through Thursday, March 7, from 4:00 AM to 2:00 PM, an intermittent lane and shoulder closure will be in place on westbound U.S. 422 between Evergreen Road and Armand Hammer Boulevard.
  • Monday, March 4, through Thursday, March 7, from 9:00 AM to 6:00 PM, an intermittent lane and shoulder closure will be in place on eastbound U.S. 422 between Armand Hammer Boulevard and Evergreen Road.

Drivers are reminded that Sanatoga Road between Linfield Road and East High Street will be closed and detoured 24/7 beginning Monday, March 4, through Friday, April 15, for water and sewer relocation. Motorists will be directed to use Linfield Road, Evergreen Road and High Street.

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

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.

Motorists can check conditions on more than 40,000 roadway miles, including color-coded winter conditions, by visiting 511PA, which is free and available 24 hours a day, provides traffic delay warnings, weather forecasts, traffic speed information and access to more than 1,000 traffic cameras.
