U.S. 422 to Close Next Wednesday and Thursday Nights for Construction in Pottstown Area


King of Prussia, PA –  Eastbound and westbound U.S. 422 will be closed and detoured at night next week for various construction activities under a project to improve and reconstruct 1.2 miles of U.S. 422 from just east of the Schuylkill River bridge to just west of the Montgomery County line, the Pennsylvania Department of Transportation (PennDOT) announced today.

The work schedule is:

  • Wednesday, September 25, from 9:00 PM to 5:00 AM, westbound U.S. 422 will be closed and detoured from the Stowe Interchange to the split with Benjamin Franklin Highway. During the closure, westbound U.S. 422 motorists will be directed to exit at Stowe, turn left on High Street and continue on High Street until it merges with U.S. 422; and
  • Thursday, September 26, from 9:00 PM to 5:00 AM, eastbound U.S. 422 will be closed and detoured from the split with Benjamin Franklin Highway in Douglass Township, Berks County, to the Route 100 (Pottstown Pike) Interchange in North Coventry Township, Chester County. During the closure, eastbound U.S. 422 motorists will be directed to continue on Benjamin Franklin Highway/High Street and turn right onto southbound Route 100 (Pottstown Pike) to access the ramp to eastbound U.S. 422.

Drivers are advised to allow extra time when traveling near the work areas because backups and slowdowns will occur. All scheduled activities are weather dependent.

Under this improvement project, PennDOT is reconstructing U.S. 422 on both existing and new alignments; reconfiguring the U.S. 422/Stowe Interchange to a diamond configuration; removing and replacing the existing ramps and culverts; installing new Intelligent Transportation Systems (ITS) equipment, message boards, signing, pavement markings, lighting, concrete median barriers, median glare screens and guide rail; upgrading stormwater management facilities and pipes; and constructing and restoring wetlands. The project is scheduled to be completed this fall.

H & K Group, Inc. of Schwenksville, Montgomery County, is the general contractor on the $35,620,846 improvement project which is financed with 100 percent state funds from Act 89, Pennsylvania’s Transportation Plan. For more information, visit
