Topanga Canyon Boulevard Sees Minor Rockfall, Debris Flow During Saturday Rainstorms

Published:

State Route 27 from Pacific Coast Highway to Grand View Drive remains closed

LOS ANGELES – Saturday morning rainfall brought minor rockfall and debris flows to the stretch of Topanga Canyon Boulevard/State Route 27 (SR-27) between Pacific Coast Highway and Grand View Drive. 

Caltrans crews evaluating the highway on Saturday noted several minor debris flows as well as locations where small-to-medium-sized rocks had fallen onto the highway from slopes throughout the work zone. Maintenance crews were working to clear the debris.

The highway remains closed. It will reopen after the storms pass and crews have removed all hazards. They are also monitoring the recovery work zone on State Route 1/Pacific Coast Highway, but there are no major impacts at this time. 

Motorists are encouraged to avoid unnecessary travel during this storm. If traveling, check local weather alerts before heading out and use headlights and wipers when driving through rainstorms. Expect delays and never drive through moving water. Remember, standing water may be deeper than it appears. 

Caltrans District 7 will continue to share daily updates through the weekend via news release and on its social media pages, including X, Instagram and Facebook. Motorists can check current traffic conditions on the Caltrans Quickmap.

This stretch of SR-27 is an active work zone for ongoing recovery efforts from the Palisades Fire and winter storms. It is typically closed to the public from midnight to 5 a.m. daily.
