Mudslide Shuts Down Topanga Canyon Boulevard

A stretch of Topanga Canyon Boulevard was shut down Wednesday morning due to a mudslide.

The 3.6 mile stretch of the road between Pacific Coast Highway and Grand View Drive was shut down until further notice due to a slide in the canyon at postmile 1.2, according to Caltrans.

"The closure is to protect the public from serious injuries and fatalities. As Caltrans works to restore the road, it will maintain access for emergency responders. Crews are also monitoring the recovery work zone on State Route 1/Pacific Coast Highway, but there are no impacts at this time," Caltrans said in a release.

Topanga Canyon Boulevard has been subjected to nighttime closures due to ongoing roadwork. It was also shut down Tuesday morning temporarily due to the rainstorm but reopened later that day.

Tuesday's closure means the road will be shut down to the public around the clock until further notice.
