Bridge Scour Mitigation Project

The project involves the structural retrofit of 14 bridge bents on the State Route 20 Sutter Bypass Bridge (No. 18-0005) located between S Tarke Road and W Butte Road in Sutter County, California, to mitigate hydraulic scour through the installation of steel bracing parallel to the stream flow. Each bent, composed of five 16-inch diameter column piers, will be reinforced to enhance structural integrity and ensure continued safe operation of the bridge under flood control standards. The work is authorized under Permit 16764 and classified as a minor alteration to an adopted flood control plan under California Code of Regulations, Title 23, Article 3, Section 6. Environmental compliance has been established through a Mitigated Negative Declaration under the California Environmental Quality Act, and the project was approved on August 15, 2025, by the Central Valley Flood Protection Board. The place of performance is Yuba City, California, with all in-place construction and inspection occurring at the bridge site. The solicitation number is WA2025057, posted on August 18, 2025, with submissions due by August 15, 2025, to the State Clearinghouse in Sacramento.
