Document Description
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 124 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 to the north of the existing bridge on a new alignment. The bridge structure would consist of a cast in place, post-tensioned box girder. The bridge abutments would be located along the banks of South Fork Willow 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 and 25 feet downstream of the bridge to prevent erosion along the creek banks. It is anticipated that the excavation for the abutments would not exceed 10 feet (approximate) below the existing ground surface. Approximately 1,200 feet of County Road 303 would be reconstructed. The proposed alignment for the road approaches has been developed so that traffic may continue to use the existing bridge and roadway while the new bridge and approaches are being constructed.
