The existing four-lane roadway with a 10-foot median and 12-foot-wide shoulders was converted into a six-lane facility with three 12-foot travel lanes in each direction, a 26-foot median, and 12-foot-wide outside shoulders.
The project also included replacement of mainline bridges carrying the Turnpike over U.S. 422/N. Gulph Road, Glenhardie Road, and Thomas Road, plus lengthening of culverts, construction of sound barriers at certain locations, and construction of stormwater management facilities and other drainage improvements across the project.
The original project was six miles in length from the Route 29 Interchange (Milepost 320) to the Valley Forge Interchange (Milepost 326).
Due to litigation and the current financial challenges facing the Commission, it was broken into two separate construction contracts: This project, plus a second contract for the western two-thirds of the corridor from the Route 29 Interchange (Milepost 320) to the Valley Forge Service Plaza (Milepost 324).
