Devil’s Slide Breakthrough Video and Links
The “breakthrough” media event for CALTRANS’ Devil’s Slide Tunnel project was this past Friday. A large crowd of politicians, news crews and locals were on hand as a road-header broke through a shotcrete face in a ceremony to mark the completion of the excavation portion of the first of two tunnels. It will still be over a year until the tunnels are opened to traffic. The second tunnel is expected to breakthrough as early as this week. (Photo by SFGate.com)
