ALAMEDA COUNTY and CONTRA COSTA COUNTIES – The California Department of Transportation (Caltrans) will conduct its annual mandatory emergency response drill at the State Route 24 (SR-24) – Caldecott Tunnels, Westbound, between Oakland and Orinda.


The mandatory six-hour emergency response drill begins Friday, December 12 at 10:00 PM and concludes Saturday, December 13 at 4:00 AM. The exercise is weather permitting.


For the safety of crews and the public, Bore 4 will be closed.  Traffic will be redirected to Bore 3 during the drill.  Bores 1 and 2 will remain open during the exercise.


Traffic control and message signs will be provided ahead of the tunnel bores to help direct motorists.


The emergency management exercise will be a coordinated effort including the CHP, Oakland Fire Department, Moraga-Orinda Fire District, and Caltrans-Tunnels & Tubes Department Staff.


During this exercise, there will be fire simulation, crash simulation, and simulated smoke. Motorists should expect delays and plan for extra travel time.
