County Road 305 over Watson Creek Bridge Replacement Project

County Road 305 over Watson 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 34 feet wide and 86 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 75 feet to the south of the existing bridge on a new alignment. The bridge structure would consist of a multi-span, continuous reinforced concrete slab on either spread footings or cast-in-drilled-hole (CIDH) piles. The bridge abutments would be located along the banks of Watson 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 50 feet upstream of the bridge to prevent erosion along the creek banks. It is anticipated that the piles for the abutments and/or piers would not exceed 35 feet (approximate) below the existing ground surface. Approximately 875 feet of County Road 305 would be reconstructed. The existing bridge and County Road 305 alignment would be used for project access.
