Devil’s Slide Tunnel, Project Updates and Geotechnical Info
Devil’s Slide is an infamous landslide along California’s Highway 1 or Pacific Coast Highway near Pacifica, just south of the San Francisco Bay area. Caltrans’ Devil’s Slide Tunnel project is an effort to bypass that slide and make the heavily traveled roadway safe for drivers and to eliminate the maintenance and traffic hassles caused by slope failures blocking the road. We first covered the project back in September of 2007 when the tunnel portion of the project commenced.

More links and videos are at the end of the post. (Photo by Kim Komenich, San Francisco Chronicle). […]
