Highway 37 In California Shut Down This Weekend And Possibly Overnight Next Week


A  major portion of Highway 37 between Vallejo and Sonoma, California, will be closed in both directions this weekend and possibly next week for major maintenance and paving projects, Caltrans officials said.

Last weekend the highway was scheduled to be shut down until Monday, but drivers got a reprieve from the backed-up traffic when roadwork completed early and crews opened up traffic in both directions Saturday at 8 p.m.

Highway 37 will be closed again this weekend between Highways 121 in Sonoma County and Highway 29 in Solano County near Vallejo from 10 p.m. Friday, Sept. 26 through Monday, Sept. 29 at 5 a.m, according to Caltrans’ current work schedule.

If more work is need, Caltrans also plans to have it closed over the course of five nights – between 10 p.m. and 5 a.m., Monday, Sept. 29 through Friday, Oct. 3.

During the closures, westbound Highway 37 motorists should use northbound Highway 29, to southbound Highway 121 in Napa County, and re-enter Highway 37 at the 121/37 interchange.

Eastbound Highway 37 motorists should use northbound Highway 121, then southbound Highway 29, and re-enter eastbound Highway 37.

A concrete median and the lack of space on both shoulders due to wetlands means workers can’t just move traffic to the side and must shut down the road completely.

Official say motorists should follow detour signs and expect delays. The six-mile artery that runs east-west carries about 40,000 cars every day and routinely backs up at peak times even with no road work underway.
