Highway 37 closures planned for road repair project

Overnight closures of Highway 37 in Sonoma County are planned for next month during a road repair project.

Crews will seal broken asphalt and make other repairs along the highway between Walnut Street in Vallejo and Highway 121, Caltrans said.

The bulk of the work is scheduled to take place overnight on weekdays from Aug. 2 through Aug. 13.

One side of the highway will be closed at a time. The eastbound side will be closed between 10 p.m. and 6 a.m. on “various” nights, Caltrans said.

The westbound side, including the Walnut Avenue onramp in Vallejo, will be closed from 7 p.m. to 5 a.m.

Drivers are urged to use highways 121 and 29 as alternate routes, Caltrans said.
