- Mt. Murphy Road Bridge Project
- The Project would construct a post tensioned cast-in-place (ClP) concrete box girder bridge built in two stages. The ClP concrete box girder bridge design provides a low maintenance structure that requires a minimal level of repair during its service life (i.e. biennial inspections, occasional joint replacement, and deck rehabilitation as needed). The total replacement bridge length is approximately 445 ft and is anticipated to be composed of two 130 ft end spans and one 185 ft main span. The proposed new bridge and lane configuration will provide two 11-foot lanes, two 2-foot shoulders, an 8-foot sidewalk, and Caltrans Type 85 barriers. The proposed sidewalk would be on the upstream side of the bridge and tie into Mt. Murphy Road on either side of the new bridge. A cable-stay system or portals would be installed at the piers. The structure width necessary to accommodate the roadway, sidewalk, and barriers is approximately 38 feet.
