3 miles of Highway 12 in Santa Rosa set to close for repaving

Three miles of Highway 12 in Santa Rosa will be closed beginning later this month.

Caltrans will shut down all eastbound and westbound lanes of the highway stretching from Fulton Road to Dutton Avenue between 8 p.m. and 8 a.m. starting Sept. 22.

The closures are expected to last until Sept. 25. One eastbound and westbound lane will be open during the day.

Crews will repave the stretch of highway as part of a project that began in July.

Caltrans has been waiting for warmer and drier weather to allow the cement and asphalt to properly cure.

The full repaving project, from Farmers Lane to Llano Road, will replace about 6 miles of the highway.

Caltrans will postpone the closure if a red flag warning is issued for the weekend.
