Lane Closures on U.S. 422 Promise Week of Delays for Montgomery County Commuters

Traffic Alert

LOWER POTTSGROVE TWP, PA — Motorists navigating through Montgomery County next week can anticipate significant delays as the Pennsylvania Department of Transportation (PennDOT) undertakes extensive construction on U.S. 422. The $83.6 million project, aimed at reconstructing and improving a 2.1-mile stretch of the expressway, will necessitate a series of lane closures that promise to test the patience of daily commuters.

From Monday, May 13, to Thursday, May 16, eastbound and westbound lanes between the Route 724 and Route 100 interchanges will see closures from 7:00 PM to 5:00 AM for the installation of an Intelligent Transportation System (ITS). Additional lane closures will occur throughout the week during daytime hours for shoulder and roadway reconstruction, as well as bridge construction activities on Sanatoga Road.

Perhaps most disruptive will be the intermittent 15-minute traffic stoppages and pacing operations scheduled for May 15 through May 17, designed to protect both motorists and workers during controlled rock blasting sessions essential for drainage construction. These interruptions, occurring between 11:00 AM and 1:00 PM, are expected to cause substantial backups.

The comprehensive project, which stretches from the Sanatoga Interchange to Porter Road in Lower Pottsgrove Township, aims not only to replace aging infrastructure but also to enhance travel safety by improving curve radii, shoulder widths, and vertical clearances. With all scheduled activities subject to favorable weather conditions, PennDOT advises drivers to prepare for delays and consider alternative routes where possible.
