​The Transportation Authority of Marin (TAM) is conducting a Highway 101 interchange study and wants input via an online survey.

Many of the Highway 101 interchanges were built in the 1950s and 1960s and have not been altered 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.


Survey results will be used to identify specific areas most in need of improvement. The survey will be open through Friday, April 16, 2021.

MTC and TAM and transportation partners.
