Hwy 101 Will be Closed Sporadically Friday Night

Highway 101 in the Petaluma area will be closed several times for 15-minute intervals Friday night, Caltrans says.

The closures at the Old Redwood Highway interchange will happen between 10 p.m. and 6 a.m., and will affect both directions of the freeway and on-ramps in both directions, at various times.

"During the closures traffic will be detoured while workers adjust falsework for the new bridge," Caltrans said in a press release. "Falsework is a temporary structure that will support the components of a bridge during construction."
