Nighttime Lane Closures on State Route 29 (Sonoma Boulevard) from the Napa/Solano County Line at Mini Drive to Missouri Street
Monday, Oct. 13 through Nov. 21, lane is scheduled to be closed from 8 p.m. until 6 a.m. each night
SOLANO COUNTY – Caltrans is scheduled to start construction on the Rehabilitation and Complete Street Project on State Route 29 (Sonoma Boulevard) in October.
This work is scheduled to begin Monday, Oct. 13, from the Napa/Solano County line at Mini Drive and span the 6 miles to Cal Poly Maritime Academy. From Oct. 13 to Nov. 21, work is scheduled from 8 p.m. until 6 a.m. each night. Work will be seen from the Napa/Solano County line at Mini Drive to Missouri Street.
All work depends on weather.
The project is estimated to be completed in the Fall of 2026.
This project will consist of the deconstruction of current medians and curbs. The construction activities may be noisy and create dust at times as work will be done by jackhammering and other construction equipment.
This project will require a lane closure with one lane open for motorist and traffic control in place. Daytime access is expected to be available for motorists. While construction is occurring, there will be a CHP presence in place.
