Caldecott TunnelThe Caldecott Tunnel is a three bore tunnel in Oakland, California. The tunnel is signed as a part of California State Highway 24, and connects Oakland to communities in Contra Costa County, through the Diablo Range. The tunnel is named after Thomas F. Caldecott, president of Joint Highway District 13, which built the first two tunnels. The middle bore can be shifted to accommodate heavy traffic. Generally, the middle bore carries westbound traffic from about midnight to noon and eastbound traffic from about noon to midnight. Construction of the first two bores was started in 1929, and completed in 1937, and were originally known as the Brodway Low Level Tunnel. The third bore was opened in 1964 and suffered a significant tunnel fire in 1982, one of the few to have involved a gasoline truck. In 2000, the California Department of Transportation began planning the possibility of a fourth bore, due to increased traffic along the route. Bore 1 and Bore 2 are each 3,610 feet long and carry two lanes of traffic. Bore 3 is 3,771 feet in length, and also carries two traffic lanes. See also External links
