U.S. 422 Ramp Closures Scheduled to Begin Next Week for Construction in Pottstown Area


King of Prussia, PA –  Westbound U.S. 422 motorists in the Pottstown area will encounter long-term ramp closures beginning next week for construction activities as part of 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 in North Coventry Township, Chester County, West Pottsgrove Township, Montgomery County, and Douglass Township, Berks County, the Pennsylvania Department of Transportation (PennDOT) announced today.

The work schedule is:
• Wednesday, December 13, through fall 2019, the ramp from westbound U.S. 422 to the Stowe Interchange will be closed and relocated about a quarter-mile west of the existing interchange.  U.S. 422 motorists will be directed to continue west and exit at the new temporary ramp to the Stowe Interchange; and
• Wednesday, December 13, through fall 2019, the ramp from Grosstown Road at the Stowe Interchange to westbound U.S. 422 will be closed and detoured. During construction, Grosstown Road motorists will be directed to take High Street/Benjamin Franklin Highway to access westbound U.S. 422.
Drivers are advised to allow extra time when traveling near the work area overnight because backups 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.
H & K Group, Inc. of Schwenksville, Montgomery County, is the general contractor on the $35,581,408 improvement project which is financed with 100 percent state funds from Act 89, Pennsylvania’s Transportation Plan. The entire project is scheduled to be completed in late 2020.
