CLIENT:
Department of Transportation
Caltrans District 4
111 Grand Ave.
Oakland, CA 94612
UNIQUE FEATURES: Following many years of public input and careful evaluation of alternatives, Devil’s Slide will be by-passed by two inland tunnels, providing a safe, dependable highway between Pacifica and Montara. This is the Devil’s Slide Tunnels Project.
PROJECT VALUE: $270 million
PROJECT DESCRIPTION:
The project calls for construction of two tunnels beneath San Pedro Mountain, each 30-feet wide and 4,200-feet long. At the northern end, a 1,000-feet bridge will span the valley at Shamrock Ranch. A re-alignment of Route 1 at the southern end will provide safe transition into and out of the tunnel. Approximately one-quarter mile south of the tunnel is the site of an Operations and Maintenance facility. An earthen embankment and vegetation-covered roof will help the facility blend with natural surroundings.
