Caltrans: SR-37 Between Vallejo and Sonoma to Close for 55 Hours Starting Oct. 23 for Flood-Resilience Work
Caltrans District 4 announced on October 13 that State Route 37 will be fully closed in both directions for 55 hours, from 10 p.m. Friday, October 23, to 5 a.m. Monday, October 26, between Mare Island and Sears Point in Solano and Napa counties.
Ahead of the full closure, the westbound direction will close overnight on October 21 and 22, from 7 p.m. to 4 a.m. Crews will demolish the median and install temporary barrier to shift both directions of traffic onto the westbound lanes. Once the shift is complete, crews will focus on the eastbound lanes, raising portions of the roadway by about 3 feet to improve resiliency and address flooding concerns along the corridor. Caltrans said crews are expediting the work as part of emergency preparedness for El Niño storm season, and changeable message signs have been deployed across the region.
A further overnight secondary closure is scheduled from 10 p.m. November 13 to 5 a.m. November 15 to remove the temporary barrier and complete the traffic shift. All work is weather dependent.
