PCH Closure on March 26 Adds to Local Road Closures, Seek Alternative Routes
The California Department of Transportation (Caltrans) has announced plans to maintain the closure of all lanes on a stretch of State Route 27 (Topanga Canyon Boulevard) indefinitely due to a weather-triggered mud and rockslide and an unstable hillside at postmile 1.8. Large rocks continue to fall at the site.
In addition, One lane of PCH will be closed at Topanga Cyn on Tuesday, March 26, from 9:00 a.m. to 4:00 p.m. for work on the City’s Traffic Signal Synchronization Project
The closure, spanning from Grand View Drive to State Route 1 (Pacific Coast Highway), will persist due to an active landslide. With more rain expected over the weekend, traffic control measures will be in place, with flaggers directing traffic from Tuna Canyon onto southbound PCH in Malibu to help make it easier and safer for drivers to cross the northbound lanes of PCH and prevent wrong-way drivers from entering one-way Tuna Canyon Rd. Additionally, striping in the median lane on PCH south of Big Rock will provide two northbound lanes. One northbound lane was taken up by K-rails to hold back the active landslide.
According to Caltrans, there is no set end date for the closure, and signs have been posted in the affected areas. Motorists are advised to plan accordingly by seeking alternate routes and should anticipate delays due to the possibility of increased traffic.
The decision to extend the closure comes as Caltrans continues to monitor the slide, which has grown larger in recent days. Rocks are still falling, water is trickling down, and the hillside remains saturated from a series of atmospheric river storms this year, creating hazardous working conditions.
While recognizing the inconvenience caused to motorists and businesses in Topanga Canyon, Caltrans emphasizes its commitment to completing the necessary work as quickly and safely as possible.
It’s important to note that all work is subject to change due to weather or construction-related issues. Real-time traffic information can be accessed at http://quickmap.dot.ca.gov/.
