State Route is fully closed between Navarro and Route 1 due to flooding of the Navarro River, an event which happens almost every December as winter rains arrive and river levels increase. As of this Thursday morning, Caltrans has announced that the road is temporarily closed until waters recede. Typically, this flooding occurs after the early winter rains, due to the development of a sandbar at the river’s mouth that leads to increases in water levels, flooding the road. There is no time estimate available for the road re-opening.
