CALTRANS District 4 announced Tuesday night that they are preparing for full closure of SR-1 Lantos Tunnels and SR-24 Caldecott due to PG&E proactive power shutoffs.
UPDATE – as of 9:30 pm, Caltrans is working through the night with our partners to provide power to both the Caldecott and Devil’s Slide tunnels. Motorists can expect them to be open during the power shutdown.
CALTRANS said the closures could occur as early as Tuesday night or tomorrow afternoon as they said tunnels cannot operate without power. The closure remains fluid and could change by the hour. CHP is urging commuters to plan alternate routes as a precaution.
The move comes as PG&E plans to shut off power to 800,000 customers in northern California.
Specifically in Contra Costa County, the shutoff could impact 40,219 Contra Costa customers in San Ramon, Orinda, Lafayette, Moraga, Pinole, Richmond, Kensington, Walnut Creek, Pleasant Hill, El Cerrito, El Sobrante, Berkeley, Canyon, San Pablo, Pittsburg, Rodeo, Concord, Albany, Antioch, Martinez.
Motorist are advised to listen for latest updates while also treating all unpowered intersections as 4-way stops while being alert for possible pedestrians and cyclists. There is also a red flag warning in effect for the East Bay Hills that go into effect at 6:00 am Wednesday.
Meanwhile, Bay Area Rapid Transit said they expect no disruption to train or station service if power is shut off.
