Intermittent Closures of Caldecott Tunnel Weeks of July 15 and 23, 2013

Intermittent nighttime closures are tentatively scheduled for the weeks of July 15 and 23, 2013. Please visit the Traffic Page of the Caldecott Fourth Bore project website for updates.
In addition to the excavation of a 3,400-foot-long tunnel north of the existing three bores, the $402 million Caldecott Fourth Bore Project includes traffic improvements on the eastern and western sides of the tunnel.  The tunnel is slated to open to traffic in late 2013.
