Third Street 4-22-2022

The City of San Rafael will be sending out weekly project updates with construction updates, traffic closure updates, and other relevant information for this project. To receive these updates, please sign up using the form at the left-hand side of the project website.

The City of San Rafael has begun an extensive 18-month Third Street improvement project to upgrade safety, infrastructure, and traffic needs for this vital thoroughfare. Third Street is a critical component of San Rafael’s transportation network and it serves tens of thousands of residents on a daily basis as they travel to work, school, recreation, and retail destinations. The City of San Rafael received an allocation from the Transportation Authority of Marin (TAM) through the Measure A program to rehabilitate Third Street. While this work will be an inconvenience for the short term, this necessary rehabilitation will dramatically improve the quality of life for the community when completed.

The Third Street Safety project construction agreement was awarded to Ghilotti Bros. Inc. by the City Council on Monday, April 18.

  • MMWD waterline connections at A Street, B Street, C Street, D Street, and E Street.
