Caldecott Tunnel Fourth Bore 8th Anniversary

Posted on

On this day in 2013, the Fourth Bore of the Caldecott Tunnel had its official opening. At the time of the groundbreaking on January 22, 2010, the Fourth Bore had the distinction of being the largest American Recovery and Reinvestment Act Stimulus project in the nation, in terms of dollars allocated. Since the ribbon cutting in 2013, the Fourth Bore has improved mobility for motorists and emergency crews, reduced delays and improved travel times, eliminated the need for daily tunnel reversals and lane merges, and enhanced safety of the traveling public and Caltrans maintenance workers.

To celebrate the Caldecott Tunnel’s anniversary, here are some facts and figures about the project, as well as some photos. For more about the Fourth Bore, visit the CCTA website.
