Caltrans breaks ground on Caldecott Tunnel fourth-bore project
Caltrans and general contractor Tutor-Saliba Corp. recently broke ground on the Caldecott Tunnel Fourth Bore Project, a four-year, $420 million project that will provide numerous jobs for Californians. The project is primarily financed by the American Recovery and Reinvestment Act of 2009.
The project is a partnership between Caltrans, the Contra Costa Transportation Authority and the Alameda County Congestion Management Agency. Funded with $197.5 million in federal Recovery Act dollars, $11 million in Proposition 1B monies, as well as other federal, state, regional and local funds, this project will reduce congestion on State Route 24 by building a fourth tunnel bore as part of the Caldecott Tunnel, linking Orinda to Oakland. Upon completion, the new northern bore and the existing northern bore will carry westbound traffic, while the two southern bores will carry eastbound traffic.
