Bay City News (via San Francisco Examiner) reports, yesterday, Caltrans brought in generators to keep two major tunnels open during the forced power outages northern California is undergoing this week. According to the article, “Both tunnels were at risk of closure due to the power shutoff” because their ventilation systems cannot operate without electricity. One of the facilities, Highway 24’s Caldecott Tunnel, is used by a minimum of 181,000 commuters each day, according to Caltrans.
