Westbound Highway 37 to close from Vallejo to Sears Point for five nights

Eastbound SR-37 will not be affected.|

Caltrans will close westbound State Route 37 between Walnut Avenue in Vallejo and State Route 121 at Sears Point in Sonoma County for five consecutive nights beginning Aug. 14, from 8 p.m. to 4 a.m. Work will conclude by 4 a.m. on Aug. 19.

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 traffic on Highway 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 Highway 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.

Due to its location atop marshy soil, Caltrans monitors pavement conditions on Highway 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.
