Westbound Highway 37 is still closed on Monday after a levee break last week flooded part of the roadway.

It affects westbound lanes between Atherton Avenue and Hwy 101.

“There’s still considerable water intrusion in multiple areas and we are still expected a full closure of westbound tomorrow with no known time when it’s going to open,” CHP Sgt. Ross Ingels. 

The California Highway Patrol reported that Caltrans District 4 crews are already making great progress as they have worked to get the water off of the road.

Crews are still working on emergency levee repairs and adding barriers, however, officials say there are still large amounts of water covering the westbound lanes in certain areas.

Work is being done 24 hours a day until it is complete and weather permitting.

Crews first began by building a road to access the levee break and are now working on the break itself.

Marin County declared a state of emergency because of damage from last week’ storms.

There continues to be no estimated time of reopening the highway.

CHP reports that one eastbound lane between US 101 and Novato Creek is open.

Officials want to remind everyone to plan ahead this week for the closure to continue.

“If you plan to continue to use 37, please plan ahead for extra delays. If you plan to seek alternate routes (101 from Sonoma County, 580/RIchmond Parkway for the Solano/Eastbay commute) anticipate extra traffic and delays. The displace commute traffic from 37 will likely fill other Bay Area roads causing extra delays.”
