Project Description:
Owned and operated by Caltrans, the $322-million Devil’s Slide project is located on State Route 1 in San Mateo County 15 miles south of San Francisco between the City of Pacifica and the town of Montara, California. The tunnels project will provide an alternative route to bypass a geologically unstable portion of the existing State Route 1 which is subject to lengthy closures, high maintenance costs, and risk of permanent failure.
Transdyn is providing a tunnel control system, environmental monitoring, telephone, CCTV, radio rebroadcast, intrusion detection, and ventilation control systems. Hardware, configuration, and testing will also be supplied by Transdyn to provide Caltrans with a complete monitoring and control system for the tunnels.
