Highway 12 Paving in Santa Rosa

ongoing

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. Pavement Condition - Caltrans will smooth out the new concrete before completing the concrete slab replacement portion of this project. In other words, the new concrete is not in its final condition. Using a grinder, Caltrans work crews will grind the rough concrete into a smooth surface before finishing this project.
