The SR 0611 Bridge was severely deteriorated and deemed structurally deficient, and the required replacement bridge involved complex environmental analysis. Many sensitive features were present around the bridge including a county park, a scenic highway, the Delaware Canal State Park, an aqueduct bridge carrying the Delaware Canal over Fry’s Run, and a stone-arch bridge listed in the National Register of Historic Places.
RETTEW replaced the existing two-span bridge with a single-span bridge. Our design eliminated a center pier in the stream, which not only obstructed stream flow but was expensive to rebuild. Our expert team prepared field surveys; preliminary engineering design including roadway plans; right-of-way requirements; maintenance and protection of traffic plans involving seven stages of traffic control; and bridge type, size, and location plans. We completed the project with the least disturbance possible to the park and the adjacent property, while creating a safe alternate route that permitted efficient traffic flow.
