The Transportation Authority of Marin (TAM) has begun the planning and environmental phase of a proposed project to construct a direct highway connection from northbound US-101 to eastbound I-580 in Marin County. TAM will complete the environmental analysis to evaluate options and work with the community and stakeholders to select a preferred alternative.
This project is a collaborative effort between TAM, the California Department of Transportation (Caltrans), and the cities of San Rafael and Larkspur.
Currently, drivers who wish to access the Richmond-San Rafael Bridge (I-580) via northbound US-101 have to exit the freeway and travel on East Sir Francis Drake Boulevard or across Bellam Boulevard to the bridge entrance. Having to drive on local streets causes congestion and traffic delays on northbound US 101 and on local streets, including Sir Francis Drake Boulevard and Bellam Boulevard.
The proposed project will allow vehicles to continue along US-101 northbound onto a new highway connector in San Rafael and merge directly onto I-580 eastbound toward the Richmond-San Rafael Bridge.
TAM is in the process of convening an ad-hoc committee and a stakeholder working group to help guide the Northbound US-101 to Eastbound I-580 Direct Connector project. Check back here for meeting schedules, agendas, presentations, minutes, and other pertinent information.
