Document Description
The project consists of the replacement of the existing St. Helena Creek Bridge on Hilderbrand Drive. The existing structure is an 80-foot long steel truss Bailey bridge with timber deck boards on steel floor beams set on concrete abutments. The net width of the Bailey bridge is 13 feet. The proposed permanent replacement bridge is a 100-foot long, 23-foot wide single-span precast pre-stressed concrete girder bridge with reinforced concrete wall abutments that would not require intermediate piers. The superstructure of the bridge will be positioned to allow flood flows to pass without overtopping the new bridge. The two existing piers will be removed. The existing east and west roadway approaches will be raised to meet the new bridge elevation.
