Document Description
The proposed project would implement the re placement of the existing bridge and reconstruction of the adjacent roadway to improve operations and safety in the project area. The new bridge would be a 65-foot-long, 42-foot-wide single-span precast, pre-stressed concrete I-girder structure supported by abutments on deep pile foundations across Buck Canyon Creek. The new bridge would consist of a 12-foot lane and 5-foot shoulder in each direction. Concrete barrie rs with tubular handrails would be installed on both sides of the. bridge. New wingwalls would be constructed; the top of the new concrete deck is expected to be approximately one foot above the existing deck. The project would also include approximately 385 feet of roadway reconstruction, including approximately 235 feet on the north side of the bridge and 150 feet on the south side of the bridge. The reconstructed roadway width would vary from the existing 26 feet to 34 feet, in order to accommodate the new travel lane and shoulder widths on the bridge. Metal beam guardrails would be installed at the approach corners.
