US 101 San Mateo County Crossings Improvement Plan

US 101 is the busiest corridor in San Mateo County. However, the freeway itself can also act as a barrier for people walking, biking, and taking transit. The Active 101 plan aims to identify crossing and corridor improvement projects and enhance travel conditions within near US 101.
