The County of Monterey Department of Public Works, Facilities & Parks proposes to replace the superstructure of the existing two-lane Gonzales River Road Bridge (Bridge No. 44C0035), over the Salinas River in Monterey County, California with a wider bridge deck that meets current American Association of State Highway and Transportation Officials (AASHTO) requirements. The proposed project would address certain existing structural deficiencies (e.g., cracks, exposed reinforcing bars, and failing joints in the superstructure) and improve the conditions for conveying flood flows. Several existing bridge piers would be rebuilt (i.e., raised) or modified for additional support; seven existing bridge piers would be removed. The proposed project would also widen the roadway approaches on the north and south ends of the Gonzales River Road Bridge (bridge) to conform to the new bridge width and profile. After construction, both the bridge and roadway approaches would contain two 12-foot lanes (one in each direction) and two 3-foot shoulders, and would meet current AASHTO minimum design speed standards. The bridge would be closed to public use during construction. Vehicular traffic would be re-routed via Chualar River Road to the north and via Arroyo Seco Road to the south.
