Night Closures of Westbound State Route 37 between Vallejo
And State Route 121 for Pavement Repairs
Closures occur 8:00 PM – 4:00 AM, Sunday, August, 14 – Friday, August 19

SOLANO COUNTY – As part of a pavement rehabilitation project, Caltrans will close westbound State Route 37 (SR-37) between Walnut Avenue in Vallejo and State Route 121 (SR-121) at Sears Point in Sonoma County for five consecutive nights beginning Sunday, August 14. from 8:00 PM – 4:00 AM. Work will conclude by 4:00 AM, Friday, August 19, 2022.

The eight-hour nightly closures will allow workers to repair deteriorated pavement and shoulders on a six-mile stretch of westbound SR-37 between Walnut Avenue and Skaggs Island Road.

Eastbound SR-37 will not be affected.

During the closures, the ramp from Walnut Avenue/Railroad Avenue interchange leading to westbound SR-37 will be closed; however, the remaining ramps will stay open.

The closure will not affect traffic traveling on SR-121 to eastbound or westbound SR-37.

Traffic that would be traveling on westbound SR-37 during the closure will detour to northbound SR-29, then connect to westbound SR-12, and finally take SR-121 to connect to westbound SR-37. (See detour map.)

Due to its location atop marshy soil, Caltrans monitors pavement conditions on SR-37, keeping an eye out for cracking and potholes that might portend future problems.

After a recent assessment, Caltrans determined that a pavement rehabilitation project should occur before the wet weather arrives this fall, causing further deterioration and making repairs more difficult. SB-1 funds will be used to make these necessary road repairs.
