Caltrans Highway 37 Paving Project Requires 4 Full Weekend Closures

NORTH BAY, CA — Caltrans is scheduled to alternately close eastbound and westbound state Highway 37 on four consecutive weekends starting Friday, April 12.

During the 55-hour weekend full highway closures, Caltrans will perform major pavement repair work on eastbound and westbound SR-37 between Solano and Sonoma counties. The 12-mile stretch of roadway has become worn and in need of repairs due to high traffic use, Caltrans said.

These full weekend closures are necessary for worker and public safety, as closing the highway during weekends is a safer alternative to 30 days of nightly closures for workers' and motorists' safety, according to Caltrans.

As the asphalt pavement is replaced, Caltrans will have detours in place and work in one traffic direction at a time.

Westbound Full Closures

The first two weekend closures start April 12 and April 19 in the westbound direction on SR-37. Traffic will be detoured beginning at the westbound SR-37 connector off-ramp to SR-29 in Vallejo.

The closures start at 9 p.m. Friday, April 12 and 19 and conclude at 4 a.m. Monday, April 15 and 22.

Motorists traveling westbound will need to exit right onto northbound SR-29 —Sonoma Blvd.—in Vallejo and continue on northbound SR-29 —Broadway— in American Canyon to SR-29/SR-12; then turn left and continue on SR-12/SR-121 —Carneros Highway/Fremont Drive — then turn left on SR-121 —Arnold Drive— and make a right back onto westbound SR-37.

Eastbound Full Closures

Eastbound Sr-37 closures are scheduled the weekends of April 26 and May 3. All eastbound lanes will be closed and traffic detoured beginning at northbound SR-121 —Sears Point— in Sonoma County.

The closures start at 10 p.m. Friday, April 29 and May 3 and conclude at 5 a.m. Monday, April 29 and May 6.

Motorists traveling eastbound will need to exit left onto northbound SR-121 in Sonoma; make a right on SR-12/SR-121 —Carneros Highway — and continue; make a right on SR-12/SR-29; and then enter left for the connector loop off-ramp back to eastbound SR-37.

Caltrans noted that all work is weather-dependent and the weekends of May 10 and May 17 are scheduled as contingency in the event any scheduled work is delayed or postponed.

The SR-37 Pave Project Hotline — 510-286-0319 — was set up for the traveling public and residents living in Marin, Sonoma, Napa and Solano counties to share any questions or concerns and learn about the most up-to-date information about the project.
