Tom Lantos Tunnels
Montara, CA
Located on Montara Mountain between Pacifica and Montara, Devil’s Slide was a treacherous section of coastal highway subject to landslides. After much community debate, it was replaced by two inland road tunnels that became the second and third longest in California. Caltrans designated Salter to do the final environmental noise study for this significant community project.
