Revisiting the Valley Forge Slip Ramp

In 2015, the Montgomery County Planning Commission, in cooperation with PennDOT, PA Turnpike Commission, DVRPC, Boles Smyth Associates, McCormick Taylor and 8 local municipalities, including Upper Merion Township, issued the Turnpike Corridor Reinvestment Project report. This study identified transportation opportunities along the Turnpike Corridor, that include potential slip ramp locations and redevelopment prospects. Since the release of the study, a few recommendations for other areas in Montgomery County have come to fruition, including construction of the new Lafayette Street Interchange and Fort Washington zip ramp. Two projects recognized in the study that have yet to be realized are in Upper Merion Township – the Henderson Road Interchange, and Valley Forge Interchange Modernization into Moore Park, which is major focus of the District’s Transportation program in 2024.

King of Prussia District engaged Boles Smyth Associates to update the original Valley Forge West Ramps Feasibility Study, conducted in 2015. The updated study, expected to release at the end of the year, will look at existing traffic volumes, base mapping and connecting roadway changes in order to update the westbound on/off ramp designs and cost estimates. This segment of the proposed interchange would have the greatest impact by reducing congestion at the existing Valley Forge toll plaza and surrounding roadways, while increasing the redevelopment potential in Moore Park. The Valley Forge West Ramps Feasibility Study will provide crucial data and design updates to inform King of Prussia District’s next steps for achieving this important transportation enhancement.
