Dover Canyon Road at Jack Creek Bridge Replacement Project (300514/ ED 19-132)

Dover Canyon Road at Jack Creek Bridge Replacement Project (300514/ ED 19-132)

The roadway geometric design is based on AASHTO (American Association of State Highway and Transportation Officials) A Policy on Geometric Design of Highways and Streets, supplemented by the Caltrans Highway Design Manual and San Luis Obispo County standards as determined applicable. The bridge design is based on AASHTO LRFD Bridge Design Specifications with the Caltrans Amendments. The bridge seismic design is based on Caltrans' Seismic Design Criteria. The bridge design also utilizes Caltrans' Memo to Designers and Bridge Design Aids. The existing bridge is a single-span, simply-supported, steel Warren pony truss with steel floor beams and a timber deck. The existing structure is founded on concrete spread footing abutments and is 63 feet long by 16 feet wide, with a clear width of 15. 75 feet between the bridge rails. The new bridge is proposed to be a single-span, precast prestressed concrete slab unit bridge slightly longer than the existing bridge. The replacement structure will be approximately 79 feet long, allowing it to clear Jack Creek and align the abutments with the approximate existing top of bank. The structure will be approximately 26 feet wide to accommodate two 9-foot lanes, 2-foot shoulders, and barriers. The abutments will sit on spread footing foundations with cast-in-drilled-hole piles anchoring them to the bedrock. Tree removal and vegetation clearing will likely be required. See NOC for full details.
