Title
Geysers Road over Frasier Creek Bridge Replacement Project
Description
The Sonoma County Department of Transportation and Public Works (DTPW) proposes to construct a new bridge on the existing alignment of Geysers Road over Frasier Creek. Traffic on Geysers Road will be conveyed over a one-lane temporary bridge that will be constructed on the upstream alignment. The temporary bridge will require temporary reinforced concrete spread footings. The hillside where the temporary bridge will be constructed has a steep slope. In order to retain this hillside, a temporary shoring wall is required along the northwest side approximately 120 feet in length. After demolition of the existing bridge and construction of the new bridge is complete, the temporary bridge including the abutments and shoring walls will be removed and the adjacent hillside will be graded back to a stabilized slope. The new bridge will be 80 feet long, the new abutments will be located further up the creek bank from the existing abutments. A single span bridge is proposed, consisting of a cast-in-place reinforced concrete box girder type approximately 32ft wide, with two 11ft travel lanes and two 3ft shoulders, with no bike lanes or sidewalk.
