DANVILLE -- Photographs of the Caldecott Tunnel's fourth bore project are on display through Jan. 5 at the Museum of the San Ramon Valley, 205 Railroad Ave.

Admission is $3. Hours are 1 to 4 p.m. Tuesdays through Fridays, 10 a.m. to 1 p.m. Saturdays and noon to 3 p.m. Sundays.

The $402 million bore project is expected to open to traffic in late 2013. The Federal Highway Administration, the state Transportation Department, the Metropolitan Transportation Commission, the Contra Costa Transportation Authority and the Alameda County Transportation Commission teamed up on the project to build a two-lane fourth bore north of the existing Caldecott tunnels.

Karl Nielson, of the MTC, and John Huseby, of Caltrans, took photos of the tunnel excavation, which began in August 2010, and of workers on the job. Their photos will visit other venues in Contra Costa and Alameda counties through the summer of 2013.

"Because Caltrans cannot provide tunnel tours for the public, we've done the next best thing," Fourth Bore Public Information Officer Ivy Morrison said in a news release. "We're bringing the Fourth Bore to communities throughout Contra Costa and Alameda counties in the form of a traveling photo exhibit."

The photos will be displayed concurrently at the Alameda Museum from October to December. They will then be displayed at the Rockridge Library from January to February, the Lafayette Library from March 1 to April 1, the Clayton Historical House from March 1 to April 30 and the Orinda Library in July.
