Extensive road construction on US 422 is impacting commuters in Montgomery County

LOWER POTTSGROVE TWP, PA – The Pennsylvania Department of Transportation (PennDOT) has unveiled plans for a major construction initiative on US 422, signaling a week of potential delays for commuters in Montgomery County. The $83.6 million project aims to reconstruct and improve approximately 2 miles of the highway, including replacing major bridges between the Sanatoga Interchange and Porter Road in Lower Pottsgrove Township.

Beginning Monday, April 22 through Thursday, April 25, motorists will experience lane and shoulder closures on eastbound US 422 between Keim Street and Evergreen Road from 9 a.m. to 5 p.m. This is part of the shoulder reconstruction efforts, which will also include westbound closures from 5 a.m. to 2 p.m. between Evergreen Road and Armand Hammer Boulevard, extending through Friday, April 26.

In addition, Sanatoga Road will experience lane closures with flagging Monday through Friday from 7 a.m. to 5 p.m. to facilitate bridge construction. In a more disruptive measure, controlled blasting of rocks for drainage construction will necessitate intermittent 15-minute traffic stops and steps in both directions on US 422, between Evergreen Road and Armand Hammer Boulevard, from Wednesday, April 24 through Friday, April 26 between 11:00 AM and 1:00 PM.

These works are critical for the safety of both motorists and construction workers, with the aim of mitigating the impact of excavation work on traffic flow. PennDOT advises travelers to allow additional time for travel through these areas to accommodate expected delays, stressing that all planned work is subject to favorable weather conditions.

The ambitious Section M1B project aims not only to reconstruct US 422, but also to realign certain sections for better horizontal curve radii, shoulder widths and vertical clearance, improving overall travel safety and efficiency. Major structural improvements include the replacement of a culvert at Sprogels Run and a single-span bridge over Porter Road with a new two-span bridge. In addition, reconstruction and widening of the bridge over Sanatoga Road and Sanatoga Creek is planned, further adding to the comprehensive scope of the project.
