Highway 12 Paving in Santa Rosa

In early July 2023, Caltrans began a paving project on a three-mile stretch of State Route 12 (SR-12) between Llano Road and Farmers Market Road in Santa Rosa to replace worn-out pavement. 

This section of Highway 12 is composed of two types of pavement.  From Llano Road to Fulton Avenue the highway is composed of asphalt, while the section between Fulton and Farmers Lane is composed of concrete slabs.  As such, different construction and paving strategy will be used to revamp the pavement.  

During the project, Caltrans will also replace 11,000 feet of guardrail.
