Williams Creek Bridge at Powerhouse Road (10C-0166) Replacement Project
MND - Mitigated Negative Declaration
Present Land Use
Mendocino County, in conjunction with the Caltrans, and the Federal Hwy Administration, is proposing to replace the Williams Creek Bridge at Powerhouse Road (10C-0166). The project proposes replacing an existing single-lane, single-span, dual railroad flatcar with timber-deck bridge structure (41 ft. long by 23 ft. wide, dual width). The existing bridge is classified as structurally deficient with a sufficiency rating of 47.6, and is eligible for replacement under the FHWA Bridge Program administered by Caltrans. The new structure will conform to Caltrans freeboard standards for 50- and 100-year flood events. The new bridge, with a clear width of 28 ft, will provide a safer structure for vehicles. Construction is planned for 2018 or later and will take approx four to five months to complete.
