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.

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.
