SOLANO, NAPA AND SONOMA COUNTY – Caltrans is continuing the needed work to repair a segment of State Route 37 (SR-37) that floods and sometimes leads to the closure of the route during the storm season.
An overnight closure will be implemented on Monday, Nov. 16. on Eastbound SR-37 as part of emergency preparedness for El Niño storm preparedness. The westbound side will be open to traffic. Crews will be shifting K-Rail and applying temporary stripping for the next stage of work.
Schedule:
Start: Nov. 16. at 10 p.m.
End: Nov. 17 at 6 a.m
What to expect?
Eastbound traffic will have to detour. Use alternate routes.
Westbound traffic will be able to travel through SR-37, drivers are advised to slow down, expect delays and allow for extra travel time through the construction zone.
