Caltrans TCB Road Closure Update 5-21-24

Bulldozers and excavators are pushing down landslide material to SR-27, where dirt, rocks and boulders are being moved away by loaders so the pile doesn’t grow too big and spill over into the environmentally sensitive Topanga Creek. Work is continuing 24/7 seven days a week.

Trucks are hauling away dirt, rocks and boulders to various locations from about 8 p.m. to 5 a.m., traveling on the closed section of SR-27 to Pacific Coast Highway (State Route 1). Circular routes are generally south and north.

Caltrans is monitoring the temporary signals at Tuna Canyon Road most mornings from about 8:30 a.m. to 10 a.m. to ensure the system is working properly. But motorists can expect delays at times depending on the amount of traffic.

Caltrans has installed fences to block access to the work zone. Please respect this so we can proceed quickly and safely. Interruptions cause all work to stop.

We now have a website on the Caltrans District 7 page: State Route 27 Landslide Recovery Plan | Caltrans
