Pathway Microsurfacing

Preventative maintenance from Almonte Boulevard to Gate 6 Road


Work Complete

Microsurfacing work on the southern stretch of the Mill Valley/Sausalito Pathway is complete. The pathway is open.


Short-term Closure of Mill Valley/Sausalito Pathway

The Mill Valley/Sausalito Pathway will be closed on Monday, October 18 from Gate 6 road to McGlashan Pathway. On Tuesday, October 19  the pathway will be closed from McGlashan Path to Almonte Boulevard.  Closure hours are approximately from 8:00 a.m. to 5:00 p.m each day. 

Please respect closure signs and avoid the area. The County has provided early notice and onsite signage to provide path users time to arrange for alternate transportation. Shuttles will be available for bicyclists and pedestrians who are not aware of the closure. Shuttle capacity is limited and wait times could be more than 30 minutes. Thank you for your patience.


Microsurfacing Work Begins

About a mile of the Mill Valley/Sausalito Pathway is undergoing a surface treatment for preventative maintenance. Construction crews are scheduled to be on site the first week of October. They will begin preparations for the improvements, which include grinding uplifted pavement, crack sealing, microsurfacing, and repainting striping.

The work is expected to take three to four weeks. Construction will take place on weekdays during daytime hours. Construction crews will strive to minimize disruption to pathway visitors, emphasizing safety. Signage is posted in the area to alert the public about construction activities, and nearby neighbors are receiving advance notice from Parks staff. Toward the end of the project, work will require closure of the pathway on two separate occasions, for approximately 24-48 hours. Exact dates for closure will depend on weather and tidal conditions as work progresses.


The popular and scenic Mill Valley/Sausalito Pathway connects two southern Marin cities, facilitating non-motorized access to neighborhoods, shops, schools, several sports fields, and a dog park. The path has an average of 2,500 users daily and over 5,000 on some of its busiest days. In addition to serving as a commuter link, it is a Safe Route to School for several Marin schools. Several pathway bridges were repaired recently.

The targeted surface repairs will improve ease of travel on a section of the pathway. This portion of the path has not been repaved since 1981. Because longer term sea-level rise adaptation planning is taking place regarding Bothin Marsh, this project is microsurfacing maintenance work and not a full repaving.
