Full and Partial Closures of Westbound State Route 12 in Santa Rosa

To Expedite Pavement Replacement

Closures begin 8:00 PM, Friday, February 23 until 5:00 AM, Monday, February 26

Full Westbound closures at night; one lane open during the day

 

SANTA ROSA – As part of a paving and concrete slab replacement project, Caltrans will alternate partial and full closures of westbound State Route 12 (SR-12) in Santa Rosa between Santa Rosa Avenue and Dutton Avenue between 8:00 PM, Friday, February 23, and 5:00 AM, Monday, February 26, 2024. 

The closures will be divided into day and night shifts. During night closures, the westbound freeway between Santa Rosa and Dutton Avenue will be closed.  During day closures one lane will be open and one lane closed.

During the night shifts (8:00 PM – 8:00 AM), the westbound direction of the freeway will be fully closed, except on Monday, February 26, when the closure ends at 5:00 AM. Detours will guide motorists around the closed portion of the freeway.  

Route 12 Westbound Closure

During the day shifts (8:00 AM – 8:00 PM), one of two lanes in the westbound direction will be closed. Motorists traveling westbound on SR-12 between Santa Rosa Avenue and Dutton Avenue should prepare for significant delays or choose an alternative route. 

The weekend closures will allow Caltrans to expedite the demolishing and recasting of concrete pavement slabs, which would take much longer to complete during typical night closures.  

The slab replacement is part of a larger project to rehabilitate a three-mile stretch of SR-12 between Llano Road and Farmers Lane in Santa Rosa, which began in June 2023
