Caltrans crews reopened the 3.6-mile stretch of Topanga Canyon Boulevard/State Route 27 (SR-27) between Pacific Coast Highway and Grand View Drive, around 10 a.m. Thursday, after updated forecasts showed less-than-expected rainfall in the canyon. It remains open, weather permitting.
The agency had closed the highway at 10 p.m. Sunday in anticipation of strong storm systems moving through the Los Angeles area. The roadway remained shut down as multiple debris flows impacted the corridor, and additional storm activity was forecast.
The reopened segment runs through an active construction zone as crews continue recovery efforts following the devastating Palisades Fire and subsequent winter storms. While access has been restored, restrictions remain in place.
SR-27 is currently closed nightly from midnight to 5 a.m. In addition, motorists should expect traffic controls, including a roughly half-mile one-way traffic section south of the Topanga town center.
Caltrans is urging drivers to use extreme caution when traveling through the area. A 25-mph speed limit is strictly enforced within work zones, and motorists must follow all posted signage and directions from traffic controllers. Parking, stopping, and pedestrian access are prohibited in active work areas.
Drivers are also advised to be especially alert around blind curves, where stalled traffic may be encountered ahead of one-way sections. Workers and slow-moving construction vehicles remain present throughout the corridor, and fines may be doubled for violations within designated work zones.
Motorists can check real-time traffic conditions using Caltrans’ QuickMap online tool.
