Route 23 and N Gulph Rd. Intersection Improvements​

​Project Location


Overview​

This project will relocate a section of existing Valley Forge Road (Route 23) and North Gulph Road (SR 3039) to allow for a new "gateway" area for the Valley Forge National Historical Park (VFNHP). This project is the final project in a series of projects to improve U.S. 422 in the Valley Forge area called the Schuylkill River Crossing Complex (RCC) Improvement Program. Previously completed work as part of the RCC program included improvements to the Route 363/U.S. 422 interchange, replacement and widening of the U.S. 422 Schuylkill River Bridge, improvements to the Route 23/U.S. 422 interchange including relocation of the eastbound U.S. 422 off‐ramp at Route 23, improvements to the First Avenue/U.S. 422 interchange, and construction of a new trail bridge (Sullivan’s Bridge) across the Schuylkill River.

The proposed construction for this project will:
    • Relocate and widen Route 23 between North Gulph Road and County Line Road.
    • Relocate and widen North Gulph Road between Richards Road and relocated Route 23.  
    • Eliminate the existing Route 23 on-ramp to U.S. 422 Eastbound.
    • Relocate the existing underground and aerial utilities along North Gulph Road and relocated Route 23.
    • ​Update the traffic signalization at the intersection of Valley Forge Road and relocated North Gulph Road.
Additional improvements include drainage improvements, new stormwater management facilities, trail improvements, and new landscaping. An existing masonry culvert at the north end of the project which begins near Valley Forge Road and County Line Road and ends just west of Station Lane will be replaced as part of the project. Approximately 1,000 Linear Feet of the trail will be constructed within VFNHP from the Park entrance area south to Richards Road, which will ultimately connect to a future Trail along North Gulph Road planned by others. The 10‐foot‐wide trail will be constructed along the existing North Gulph Road cartway from a connection with the Joseph Plumb Martin Trail in the vicinity of the VFNHP Visitors Center.
