After nearly five decades and $439 million, the new Highway 1 bypass at Devil's Slide is set to open March 25. The bypass avoids a section of highway between Pacifica and Montara known for multiple landslides and deadly car accidents. The twin tunnels, which extend through San Pedro Mountain, will be the first new highway tunnels to open in California in nearly 50 years. They feature state-of-the-art technology with huge exhaust fans and carbon monoxide sensors. We discuss the tunnels' construction and the environmental and political roadblocks its proponents met along the way.
