County Road 200 over branch Salt Creek Bridge Replacement Project

County Road 200 over branch Salt Creek Bridge Replacement Project

The County proposes to replace the existing bridge with a slightly wider and longer bridge to improve roadway safety, improve hydraulics, and reduce scour potential. The purpose of the proposed project is to replace a structurally deficient bridge with a new structure that meets current standards and reconstruct the approaching roadway to transition between the new construction and the existing roadway. The new bridge would be a standard two-lane bridge approximately 30 feet wide and 105 feet long. The bridge would have two 12-foot-wide travel lanes with 2-foot-wide shoulders on each side. The bridge would be located along the same alignment as the existing bridge. The bridge structure would consist of a cast in place, post-tensioned single-span box girder. The bridge abutments would be located along the banks of Branch Salt Creek and would not be in the active channel. Rock slope protection may be placed around the new abutments to protect them from scouring and erosion as well as approximately 75 feet upstream and 50 feet downstream of the bridge to prevent erosion along the creek banks. It is anticipated that the excavation for the abutments would not exceed 27 feet (approximate) below the existing ground surface. Approximately 800 feet of County Road 200 would be reconstructed. A temporary detour road and low water crossing would be constructed to the south of the bridge to allow for continuous traffic flow during construction.
