Title

County Road 29 at Dry Slough Bridge Replacement

Description

The project is limited to the replacement of the existing Dry Slough Bridge on Country Road 29 with a wider bridge that satisfies current width standards. The existing 51.8-foot-long bridge is comprised of a single span reinforced concrete T-beam superstructure supported by end diaphragm abutments on unknown foundations. The proposed replacement bridge will span the slough with a single span and will be approximately 60 feet long and 40 feet wide, with two 12-foot lanes, 4-foot shoulders, and 4-foot graded aggregate base shoulder backing. The bridge foundations will consist of driven Caltrans Class 140 (Alternative W) 14-inch diameter steel pipe piles. The bridge and roadway embankment adjacent to the Slough will be protected with rock slope protection over slope protection fabric.
