The following is Traffic Advisory issued by Caltrans
Caltrans has begun a roadway and sidewalk upgrade project on a 3.8-mile stretch of State Route 12 through the City of Sonoma, between Leveroni Road and Boyes Boulevard.
Highway 12 is also known as Broadway and W. Napa Street as it travels through the City of Sonoma.
Bay Cities Paving and Grading of Concord, Calif. is the contractor on the $7 million project that includes paving, modifying traffic signals and streetlights, installing curb ramps and pedestrian beacons.
To reduce impacts and obstructions to traffic and pedestrians, Caltrans will perform most work during the evening and at night between the hours of 6:00 PM and 7:00 AM.
Caltrans will grind and repave the 3.8-mile stretch of roadway as one of the last orders of work, probably starting in late July 2021. The agency hopes to complete paving by October 31, 2021, the end of paving season in most parts of the North Bay. If not, Caltrans will return in the warmer spring months of 2022 and complete the work.
As part of the project, Caltrans will install two overhead pedestrian beacons on W. Napa Street: one at Third Street, and another located mid-block between Riverside Drive and 7th Street.
To bring the sidewalks into compliance with the Americans with Disabilities Act of 1990 (ADA), Caltrans will replace 25 curb ramps with new ADA-approved ramps.
Work began last week with the installation of temporary fences and construction signs. This week Caltrans will locate underground utilities and replace traffic signals.
