Gulph Road (SR 1012) Bridge Replacement Over Trout Creek
Tredyffrin Township, Chester County, PA

Gulph Road (SR 1012) Bridge ReplacementWBCM provided engineering services for the replacement of Gulph Road over Trout Creek. The existing bridge was an historic, single-lane stone-arch bridge built in 1917 that is listed on the National Register of Historic Places. The existing waterway opening for the bridge was undersized and caused extensive and frequent flooding of properties upstream from the bridge.

WBCM designed a 68-foot long replacement that increased the waterway opening, reduced flooding, and incorporated context sensitive design features, such as stone facing and a curved underside similar to the existing arch structure. WBCM incorporated in-stream devices to train the stream through the bridge opening and an enhanced riparian buffer along both banks of Trout Creek.

WBCM also designed significant utility relocations, including a 24-inch sanitary sewer line, a 6-inch gas main, and a 24-in water main. WBCM prepared GP-05 permits for the sanitary sewer stream crossing, the water main stream crossing and the gas main stream crossing.

WBCM prepared erosion and sediment control plans and obtained approval from the Chester County Conservation District. WBCM also prepared and obtained approval for a Joint Permit Application.
