Highway 101 Interchange and Approaching Roadways Study

Thank you for your interest in the Transportation Authority of Marin’s Highway 101 Interchange and Approaching Roadways Study!

Highway 101’s interchanges vary in age; many of them were built in the 1950s and 1960s and have not been altered in meaningful ways to meet current and future demands of vehicles, transit, bicyclists, and pedestrians. The study will identify a program of short, medium, and/or long-term projects at 12 selected interchanges to improve their operation and safety for all users.
Your feedback on this survey will be used to identify specific areas most in need of improvement and help us make Highway 101’s interchanges safer and more efficient for everyone.
