Caltrans crews were successfully able to install four portable generators at the Caldecott Tunnel, allowing the tunnel to remain open during Pacific Gas & Electric’s planned Public Safety Power Shutdown.
The threatened shutdown would have affected at least 181,000 commuters who use the tunnel every day.
Tavares said three of the generators will be used to power lights, ventilation, security systems and fire prevention equipment in the four bores of the tunnel during the outage. The fourth generator will be held in reserve.
The generators will last for at least 7 days.
