Roadways & traffic


Marin County Public Works has the responsibility for maintaining a roadway network of over 420 miles across the unincorporated areas of our county. The exceptions are state roads, city and town streets, and non-county maintained roads such as permanent roads divisions. We work to serve the Marin County's residents and visitors with the least inconvenience possible. Come rain or shine, our staff are out on the County-maintained roadways to ensure the network remains open and safe for travel.

Here you will find resources that will inform you on roadway conditions, including road closures and lane restrictions, as well as current efforts to improve the County's road network and the ability for you to bring issues to our attention.
