The Pennsylvania Department of Transportation (PennDOT) announced today that overhead bridge work is planned next week on U.S. 422 and N. Gulph Road in Tredyffrin Township, Chester County, and Upper Merion Township, Montgomery County, under the Pennsylvania Turnpike Commission's project to widen and improve the Turnpike and its bridges between milepost 324 and milepost 326.

Motorists are advised of the following travel restrictions:

  • Monday, March 27, through Wednesday, March 29, from 9:00 PM to 6:00 AM the following morning, left lane closures are planned on U.S. 422 in both directions between 1st Avenue and U.S. 202;
