Overturned Paint Truck Closes Lucas Valley Road

Road expected to reopen at 10pm when crews finish cleaning up spill

UPDATE September 11 4:45p.m. – Due to difficult terrain, cleanup operations at the site of yesterday’s overturned truck could not be fully completed today. However, at this time all lanes are open and will remain open for the duration of the weekend.

Cleanup operations will continue on Monday and will not require any lane closures as equipment and personnel will be staged off of Lucas Valley Road.

On Tuesday crews will remove remaining materials and the area will received a final inspection from the Department of Fish and Wildlife. Both lanes will be closed and no traffic will be allowed through from Westgate Dr. to Skywalker Ranch on Tuesday from 11 a.m. to 1 p.m. to accommodate these operations. Additional closures may be necessary if the area does not receive a final sign off from inspectors. The County will continue to post updates to the News Release online should the scheduled closures change.

UPDATE September 11 10:00 a.m. – Delays will continue today until 3:30 p.m. as crews finish cleaning up spilled paint. From 6 a.m. to 1:30 p.m. crews will direct traffic through one lane that that will be open from Westgate Dr. to Skywalker Ranch. 

From 1:30 p.m. - 3:30 p.m. both lanes will be closed and no traffic will be allowed through from Westgate Dr. to Skywalker Ranch. Residents who live between Nicasio Valley Road and Skywalker Ranch will still be allowed to access their homes during this time from west of the closure. 

Crews are expecting to finish the cleanup and reopen traffic in both directions after 3:30 p.m. today in time for the evening commute. 

San Rafael, CA – Lucas Valley Road will remain closed until approximately 10 p.m. tonight as environmental cleanup crews work to pump out several hundred gallons of paint which spilled from an overturned truck. The truck was carrying approximately 2,000 gallons of paint when it destabilized on a tight turn on the two lane road. An estimated 300 gallons have spilled. No injuries have been reported from the accident.

There is a hard road closure in effect in both directions of the affected section on Lucas Valley Road until approximately 10 p.m. today, which means that no vehicles will be allowed through. The closure, enforced by CHP, is from Skywalker ranch to Westgate Drive. There is a soft closure in effect at Nicasio Valley Road, prior to the closure at Skywalker ranch. Residents who live between Nicasio and Skywalker ranch will still be able to access their homes from the west of the closure on Lucas Valley Road.

The closure will remain in effect until cleanup crews have finished removing paint from the area. The Department of Public Works estimates that the road will reopen at approximately 10 p.m.

Agencies onsite include Marin County Department of Public Works, Marin County Fire, Skywalker Fire, the California Fish and Wildlife Office of Spill Prevention and Response, and Environmental Protection Agency, and Marin CHP.
