    PennDOT Completes Major Construction on U.S. 1 Widening and Improvement Project in Kennett, East Marlborough Townships

    July 29, 2026

    King of Prussia, PA – The Pennsylvania Department of Transportation (PennDOT) announced today that major construction has been completed on the $10.4 million project to widen and improve a 1.3-mile section of U.S. 1 (Baltimore Pike) from the Kennett Oxford Bypass to Greenwood Road in Kennett and East Marlborough townships, Chester County.

    Under this project, PennDOT’s contractor constructed a third travel lane on sections of U.S. 1 (Baltimore Pike) in each direction and used existing shoulders and right turn lanes to create a third lane for the rest of the corridor. In addition, the contractor milled and overlayed U.S. 1 (Baltimore Pike); built sidewalks along the north side of U.S. 1 (Baltimore Pike) from Schoolhouse Road to the Longwood Village Shopping Center entrance; eliminated the left turn movement from Orchard Avenue onto U.S. 1 (Baltimore Pike); installed two new Dynamic Message Signs; and upgraded five signalized intersections within the corridor.

    While major construction has been completed, drivers can expect to encounter periodic short-term lane closures on U.S. 1 (Baltimore Pike) through August for minor construction activities.

    Allan Myers, LP, of Worcester, Montgomery County, is the general contractor on this project, which is financed with 100 percent federal funds.
