Document Description
The Town of Ross Public Works Department (Town) proposes to replace the existing Winship Avenue Bridge (No. 27C0074) over San Anselmo-Creek, which-is-required-to ensure current-safety-and design standards for bridges and roadways are maintained. As part of the project, the Ross Valley Sanitary District (RVSD will relocate and update the existing 6-inch gravity sewer line that is currently within the existing bridge deck. The primary objective of the sewer line upgrade is to relieve hydraulic and structural deficiencies with aging RVSD infrastructure within the town of Ross. Replacement of the existing bridge structure would occur with a single span, cast-in-place or precast concrete slab type bridge with a curb-to-curb width of 20 feet and a 4.5-foot-wide walkway on the north side. The roadway profile would be raised up to 4 feet to meet flood control requirements.
