CONSTRUCTION BEGINS ON ENERGY-SAVING
LIGHTING SYSTEM IN CALDECOTT TUNNEL

Caltrans has begun construction on a more energy-efficient, brighter, and cost-effective lighting system to guide motorists through the Caldecott Tunnel on Highway 24.

The construction work, which involves replacing 2,043 lights in the three bores of the Caldecott Tunnel, is expected to be completed by year's end.

Replacement of the lights will be done between 9 p.m. and 5 a.m. Sundays through Thursdays. One bore of the tunnel will be closed during the work, and 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 new $5 million lighting system in the tunnel, which connects Alameda and Contra Costa counties along Highway 24.

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

Motorists can get lane closure information for the duration of the project by calling the Caldecott Tunnel construction information hotline at (510) 286-7395.

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