422 Project Update
Construction Continues Next Week on U.S. 422 Improvement Project in Lower Pottsgrove Township
The Pennsylvania Department of Transportation (PennDOT) announced today that construction will occur next week on U.S. 422 in Lower Pottsgrove Township, Montgomery County, 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.
Motorists are advised of the following travel restrictions:
- Monday, December 18, through Friday, December 22, from 9:00 AM to 5:00 PM, a single lane closure will be in place on eastbound U.S. 422 between Armand Hammer Boulevard and Evergreen Road for clearing, grubbing and barrier installation;
- Monday, December 18, through Friday, December 22, from 5:00 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 clearing, grubbing and barrier installation; and
- Monday, December 14, through Thursday, December 21, from 7:00 AM to 5:00 PM, Sanatoga Road will be reduced to a single lane with flagging between Linfield Road and 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.
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; and
- Improving stormwater management facilities, including two extended detention basins.
