LOWER POTTSGROVE PA – Highway construction will continue next week with lane closures on U.S. Route 422 and Porter Road in Lower Pottsgrove Township, the Pennsylvania Department of Transportation said.
The agency’s King of Prussia office indicated drivers should be aware of three lane closures that will restrict traffic:
- A single lane closure is expected Monday through Thursday (Jan. 8-11) daily from 5 a.m. to 2 p.m., on westbound 422, between Evergreen Road and Armand Hammer Boulevard, for clearing and root removal (known as “grubbing”);
- A single lane closure is expected Monday through Thursday (Jan. 8-11) daily from 9 a.m. to 5 p.m. on eastbound 422, between Armand Hammer Boulevard and Evergreen Road, for clearing, grubbing and barrier installation; and
- Porter Road will be reduced to a single lane with flagging Monday through Thursday (Jan. 8-11) daily from 7 a.m. to 5 p.m., between East High Street and Sanatoga Station Road, for clearing and grubbing.
Drivers are advised to allow extra time when traveling through the work areas. Backups and delays will occur, PennDOT warned. All scheduled activities depend on acceptable weather.
About the planned improvements
The work in Lower Pottsgrove represents an $83.6 million project to reconstruct and improve about 1.7 miles of the limited-access highway, and replace two bridges between its Sanatoga interchange and Porter Road. It is expected “to extend the design life and improve ride quality and safety” of 422, “and improve the current condition of … storm water basins, drainage inlets, slope stabilization, guide rail and signs.”
The road will be reconstructed on both existing and revised alignments to improve horizontal curve radii, shoulder widths, and vertical clearance to enhance travel and safety. PennDOT stated. A culvert at Sprogels Run, located just east of Porter Road, along with an existing single-span bridge carrying 422 over Porter Road, will be removed and replaced with a new two-span bridge. The bridge carrying 422 over Sanatoga Road and Sanatoga Creek will also be reconstructed and widened.
Additional improvements, it noted, will include:
- Reconstructing and lengthening the acceleration ramp from the Sanatoga interchange at Township Line Road to westbound 422;
- Installing Intelligent Transportation System equipment and components along the 422 corridor and on arterial roadways;
- Constructing sound barriers along portions of westbound 422;
- Upgrading existing signage and installing new signage;
- Replacing the closed system drainage system and cross culverts throughout the project limits; and
- Improving storm water management facilities, including two extended detention basins.
