Document Description
The California Department of Transportation (Caltrans) proposes to replace the existing Cordilleras Creek Bridge on United States Highway 101 (U.S. 101) at post mile 7.13 in Redwood City in San Mateo County. Two Build Alternatives are being considered. Under Alternative 1, Caltrans proposes to replace the existing triple box culvert with a new, pre-cast triple reinforced-concrete box culvert; each culvert would be 10 × 10 feet in size. Under Alternative 2, Caltrans proposes to replace the existing bridge with a new, 36-foot-10-inch single-span precast, pre-stressed bridge. The purpose of the project is to maintain connectivity and a safe highway facility for the traveling public along U.S. 101 by replacing the existing deteriorated bridge over Cordilleras Creek. The existing bridge is at the end of its service life and in need of replacement.
