LOWER POTTSGROVE TOWNSHIP, PA — The Pennsylvania Department of Transportation (PennDOT) has announced a week-long installation of temporary barriers and signs on U.S. 422 in Lower Pottsgrove Township, Montgomery County. This initiative is part of an extensive $83.6 million project aimed at reconstructing and improving approximately 1.7 miles of the expressway and replacing two bridges between the Sanatoga Interchange and Porter Road.
From Monday, December 4, through Friday, December 8, single lane closures will be implemented on both the eastbound and westbound sides of U.S. 422. Eastbound closures, from 9:00 AM to 5:00 PM, will occur between Armand Hammer Boulevard and Evergreen Road. Westbound closures, from 7:00 AM to 5:00 PM, will take place between Evergreen Road and Armand Hammer Boulevard. Motorists are advised to allow extra time for travel due to expected backups and delays. All scheduled activities are contingent upon favorable weather conditions.
This ambitious Section M1B project aims to extend the design life, improve ride quality, and enhance safety along the U.S. 422 corridor. The current condition of roadside elements such as stormwater basins, drainage inlets, slope stabilization, guiderails, and signs, which are in poor condition, will also be improved.
The project includes the reconstruction of U.S. 422 on both existing and revised alignments to improve horizontal curve radii, shoulder widths, and vertical clearance. Two significant infrastructure replacements are planned: 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 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 encompass the reconstruction and lengthening of the acceleration ramp from the Sanatoga Interchange (Township Line Road) to westbound U.S. 422, installation of Intelligent Transportation System (ITS) equipment along the U.S. 422 corridor and on arterial roadways, construction of sound barriers along portions of westbound U.S. 422, upgrading existing signage and installing new ones, replacing the closed system drainage system and cross culverts throughout the project limits, and improving stormwater management facilities, including two extended detention basins.
The Section M1B project marks the seventh construction initiative under PennDOT’s commitment 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.
