Project Info
- Title
- Caldecott Improvement Project
- Description
- Caltrans proposes the construction of a fourth bore, north of the existing bores, for the Caldecott Tunnel to reduce traffic congestion and improve safety. The project limits extend from the SR 24/SR 13 interchange in Alameda Co. to the SR 24/Gateway Blvd. interchange in Contra Costa Co. The new tunnel will be 3,389 ft. long. The project will result in permanent and temporary impacts to a total of 12.07 acres of Alameda whipsnake habitat. Project-related impacts are expected to result in the take of Alameda whipsnake, a species protected by the California Endangered Species Act (CESA).
