Motorists will have brighter, more energy-efficient and cost effective lights to guide them through the Caldecott Tunnel by the end of the year, California Business Transportation and Housing Secretary Maria Contreras-Sweet announced today.

Under the direction of the California Department of Transportation (Caltrans), the existing lights in the Caldecott’s three bores will be replaced with a $5 million energy-saving lighting system.

"This new system will be more energy-efficient than the existing lights, saving precious electricity. In addition to saving power, these new lights will emit a brighter light and cost less to maintain," Contreras-Sweet said.

The Caldecott project is just one example of the Davis administration’s focus on being energy efficient.

Replacement of the lights will be done between 9 pm and 5 am Sundays through Thursdays. One bore will be closed during the work. The other two bores, with a total of two lanes in each direction, will remain open each night.

Steiny Construction of Vallejo is the prime contractor for the work, which involves replacing 2,043 lights. Work is scheduled to begin next month in the tunnel, which connects Alameda and Contra Costa counties along Highway 24.

Installation of the new lighting system in the three bores is expected to be completed by the end of the year.

In addition, four new electronic message signs and two cameras are being installed to provide up-to-the-minute traffic information for motorists about conditions in the tunnel. That work is set for completion this spring.

The state has allocated $36 million to initiate preliminary design and environmental studies for an additional bore at Caldecott, which handles an average of 156,000 vehicles a day. Work on these studies is to begin later this year.
