Highway 1 Safety & Mobility Studies

During 2009-2012 San Mateo County conducted a two-phase public participatory planning effort to develop conceptual plans to improve Highway 1 safety and mobility between Half Moon Bay and Devil’s Slide.

Action Plan for both phases 
Phase 1 Study covering El Granada & Miramar 
Phase 2 Study covering HMB airport to Devil's Slide

Proven Safety Countermeasures

Pedestrian Crossing Islands
Modern Roundabouts
Roundabouts: Liveability Factsheet (AARP) 
Caltrans requires that roundabouts be considered when state highway intersection improvements are planned. Not only do roundabouts keep traffic moving through intersections, they dramatically reduce collisions (75% fewer injury collisions and a 90% reduction in overall fatalities).
