State Route-37 Pavement Repair Project  

Alternating overnight full highway closure on Westbound and Eastbound SR-37
Starts Monday, May 20, 2024, at 9:00 PM

Caltrans has scheduled alternating full overnight weekday closures on both Westbound and Eastbound State Route 37 to paint new lane lines on the newly paved roadway. This work is called striping work. To ensure the safety of workers and motorists, Caltrans will need to fully close Westbound and Eastbound lanes on alternating nights. However, one traffic direction of SR-37 will remain open while work is performed on the opposite traffic direction.

Westbound SR-37 between the SR-37/SR-29 interchange in Vallejo and the SR-37/SR-121 interchange in Sonoma County is scheduled to be closed Monday, May 20 at 9:00 PM until Tuesday, May 21 at 4:00 AM. Westbound SR-37 will also be closed Tuesday, May 21 at 9:00 PM until Wednesday, May 22 at 4:00 AM. Eastbound SR-37 will remain open.

Eastbound SR-37 between the SR-37/SR-121 interchange in Sonoma County and the SR-37/SR-29 interchange in Vallejo will be closed Wednesday, May 22 at 8:00 PM until Thursday, May 23, 2024 at 5:30 AM. Eastbound SR-37 will also be closed Thursday May 23 at 9:00 PM until Friday, May 24 at 4:00 AM. Westbound SR-37 will remain open.

If you have a question or want to share a concern about the project, please call the SR-37 Pave Project Hotline (510) 286-0319.
