Northbound US-101 to Eastbound I-580 Direct Connector
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.
A Stakeholder Working Group has been created to provide community input to the project team. The SWG provides a forum for the project team to understand community concerns and issues early in the project development process and creates an ongoing communication channel. The committee is comprised of volunteers representing a variety of interests in Marin County.
These meetings will be hosted as Zoom webinars with SWG members and the project team as panelists to share information and to allow interaction and input. These these meeting will be open to the public and public comments will be taken at the appropriate times.
Details regarding the meeting agendas and meeting access/log-in information will be posted on the Calendar Page at least 72 hours prior to each meeting.
