Highway 37 closure this weekend between Sonoma and Solano Counties on track

( KRON ) — Eastbound lanes of Highway 37 between Sonoma and Solano counties will be closed this weekend, beginning at 10 p.m. on Friday, May 17. The closure will be in effect between the Highway 37/Highway 121 interchange, according to Caltrans.

Eastbound lanes will be closed and traffic will be detoured at the interchange in Sonoma County. The purpose of the closure is for Caltrans to perform major pavement repair work.

The closure which begins Friday night, will conclude Monday, May 20 at 5 a.m. The closure, Caltrans added, is weather dependent.

Eastbound Highway 37 detour

Drivers headed east on Highway 37 will need to:

• Exit left onto northbound Highway 121 in Sonoma
• Make a right on Highway 12/Highway 121 (Carneros Highway) and continue
• Turn right on Highway 12/Highway 29
• Enter left for the connector loop off-ramp back to eastbound Highway 37

Beginning Monday night at 9 p.m., alternating overnight full highway closures will take effect for both the eastbound and westbound lanes of Highway 37. These closures will be for Caltrans to paint new lane lines on the repaved roadway, known as striping work.

During the striping work, Caltrans will fully close eastbound and westbound lanes on alternating nights. One traffic direction of Highway 37 will remain open while work is done in the opposite traffic direction.
