Starting from April 19, 2024, the California Department of Transportation (Caltrans) is set to initiate a significant pavement repair project on State Route-37 (SR-37) between State Route-29 in Vallejo and State Route-121 in Sonoma. This project will necessitate full closures of the highway for 55 hours on consecutive weekends*, including April 19, April 26, May 3, and May 10, 2024. The closures will commence each Friday at 9:00 PM.

Details: Caltrans has announced a crucial pavement repair undertaking on SR-37, spanning Solano and Sonoma counties, starting April 12, 2024. Over four consecutive weekends, the department will conduct comprehensive repair work on both eastbound and westbound lanes of SR-37. Each weekend, one direction of traffic on SR-37 will be closed entirely for 55 hours. These closures are essential for the completion of the repair project.

During the closure periods, detours will be implemented to redirect traffic. It is important to note that all operations are contingent upon weather conditions.

For further details, detour routes, and updates regarding this project, visit the official Caltrans website.

*Caltrans announced on April 10th that due to the current weather forecast, the planned closure of Hwy 37 will start on April 19 rather than April 12th, as originally planned.  This will shift the scheduled closures to the weekend to April 19, April 26, May 3 and May 10, 2024.
