SOLANO COUNTY- Caltrans has scheduled a nighttime full closure of Westbound State Route 37 between SR-29 in Vallejo and SR-121 in Sonoma County for Monday night, May 6, between 9:00 P.M. and Tuesday morning, 4:00 A.M. to finish remaining Striping on Westbound SR-37. Due to unfavorable weather and high winds during the weekend closure some of the work had to be rescheduled to tonight, Monday May 6. Caltrans will be completing the striping of the newly paved State Route 37 between Mare Island and Sears Point. To ensure the safety of workers and motorists, Caltrans will need to fully close Westbound lanes to safely complete the work. Detours will be set in place beginning at 9:00 P.M.
