Construction crews working on the Caldecott Tunnel’s fourth bore project are within a few hundred feet of connecting Orinda and Oakland. Caltrans has estimated that the two ends of the tunnel will connect at some point next week when crews clear the last part of theĀ 3,389-foot tunnel.

With the major portion of the project, the digging, out of the way, crews will now focus on the tunnel’s two-foot thick support shell, laying in the road and other finishing projects.

The fourth bore is still scheduled to be open to traffic in late 2013. Caltrans believes the addition of the fourth bore will help clear up traffic in a location that is backed-up regularly.
