Caldecott Tunnel Update: Two Bores Closed on Christmas Day (2026)

Caldecott Tunnel Chaos: Christmas Traffic Woes and Ongoing Construction

The holiday season brought an unexpected twist for commuters in the San Francisco Bay Area. As of noon on Christmas Day, two of the Caldecott Tunnel's four bores were closed due to a power failure, causing significant disruptions for drivers. The affected bores were Eastbound Bore 1 and Westbound Bore 3, leaving the other two bores operational but expecting delays.

The California Highway Patrol (CHP) issued a severe traffic alert, urging drivers to brace for delays and consider alternative routes. The situation is particularly challenging for those traveling on Highway 24 near Orinda, where congestion is expected to persist.

Adding to the holiday travel woes, Caltrans reported emergency construction on eastbound Highway 24 between the tunnel and Fish Ranch Road, with lanes set to close until midnight. This construction further exacerbates the traffic congestion, making the journey even more challenging for drivers.

As the story continues to unfold, drivers are advised to stay updated with the latest information. The CHP and Caltrans will provide further updates on the tunnel's reopening and the progress of the emergency construction. This developing situation highlights the challenges of managing infrastructure during peak travel periods, leaving commuters with limited options and the need for flexibility in their holiday travel plans.
