Update, 8:45 a.m. Tuesday
Highway 1 is now open from south of Encinal Canyon Road to Las Posas Road, Caltrans said Monday night. The agency warned that motorists should expect some lane blockages as crews continue clearing slides and cleaning drains.
A section of Highway 1 affected by the Woolsey Fire closed Saturday night due to mudslides and flooding — and could remain closed until Tuesday, Caltrans said.

The highway is closed from Las Posas Road in Ventura County to Encinal Canyon Road in Malibu, Caltrans said. The agency first announced the highway’s closure on Saturday night, following rainfall that pummeled the Central and Southern California coasts.
Due to Saturday’s rain, authorities issued urban and small stream flooding advisories for Santa Barbara and San Luis Obispo counties as well as slide warnings on Saturday for Highways 101 and 154. Flash flood warnings were also in effect Saturday for the Woolsey Fire burn area, including Highway 1.
The Woolsey Fire erupted in Woolsey Canyon east of Simi Valley on Nov. 8. The fire killed three people, destroyed 1,643 structures, closed Highway 101 and Highway 1 and ultimately burned 96,949 acres before reaching 100 percent containment in late November.
Portions of the Pacific Coast Highway through Malibu were closed in early December so crews could repair damage from the blaze, according to the Los Angeles Times.
While Caltrans said Saturday night that the forecast could also force Highway 1 in Big Sur to close, the agency announced Sunday morning that the road wouldn’t close, since the slide areas looked good and the incoming rain no longer looked heavy. Caltrans said they will assess the area again on Monday.
