Caltrans to Implement Partial and Full Closures of State Route 12

In Santa Rosa to Expedite Pavement Replacement

Closures start 8:00 PM, Friday, October 27, and end 5:00 AM, Monday, October 30

 

SANTA ROSA – As part of a paving and concrete slab replacement project, Caltrans will alternate partial and full closures of State Route 12 (SR-12) in Santa Rosa between Santa Rosa Avenue and Farmers Lane between 8:00 PM, Friday, October 27 and 5:00 AM, Monday, October 30, 2023. 

The closures will be divided into day and night shifts. The freeway will be fully closed during night shifts, which begin at 8:00 PM and end at 8:00 AM, except for on Monday, October 30, when the closure ends at 5:00 AM. Detours will guide motorists around the closed portion of the freeway.  

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

During the nighttime closures, eastbound SR-12 traffic will be detoured off the freeway at E. Street, where it will follow Bennett Valley Road to Farmers Lane, where it will rejoin SR-12.  

Traffic heading westbound to U.S. Highway 101 during nighttime closures will exit on Brookwood Avenue, then take Maple Avenue to Santa Rosa Avenue, where it will access U. S Highway 101.

The weekend closures will allow Caltrans to expedite the demolishing and recasting of concrete pavement slabs, which would take weeks or months 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
