I-580 Culvert Replacement (EA 0V170)

The California Department of Transportation, District 4 – Bay Area/Oakland, is planning to replace a failed culvert system at post mile 31.97 on Interstate 580 in Alameda County. Currently, a temporary steel plate covers the compromised drainage inlet and down drain, and the project will remove this interim measure to install a permanent solution. Work includes grading the roadway to gain access to the culvert, replacing the entire culvert system along with the drainage inlet and down drain, followed by backfilling and repaving the affected area. Vegetation clearing and grubbing may be necessary to facilitate construction. The project will require standard construction equipment such as asphalt concrete trucks, grinders, loaders, pavers, and rollers to complete the work efficiently. The contract, identified as I-580 Culvert Replacement (EA 0V170), was posted on June 11, 2026, as a forecast announcement with no set-aside type specified. The primary point of contact is Juliane Smith, Senior Environmental Scientist and NEPA/CEQA Specialist, who can be reached via phone or email for further inquiries. The project will occur entirely within the state of California, and additional details are available through the provided Caltrans environmental review link. While no solicitation number has been assigned yet, the announcement signals the upcoming procurement process for contractors to bid on this essential infrastructure repair.
