Snow, ice shuts down 5 Fwy through the Grapevine, roads closed due to storm-triggered mudslides

TOPANGA, Calif. (KABC) -- Storm-triggered mudflows, heavy rain and snow prompted several road closures across Southern California as the region remained under a flood watch.

Snow and icy conditions prompted the full closure of a portion of the 5 Freeway through the Grapevine overnight. The closure is in effect from State Route 126 to the Kern County line due to hazardous road conditions, according to the California Highway Patrol. The freeway closure will be in place for an unknown duration. A turnaround gate was employed near Parker Road for northbound lanes of the 5 Freeway while SR-14 remains open as an alternate route.

Before the closure, CHP officers escorted drivers when some of the snow was beginning to stick to the roadway.

The Cajon Pass was also impacted by the winter storm. The roadway saw snow overnight, but it remained open to drivers.

Meanwhile, Pacific Coast Highway west of Topanga Canyon Boulevard was closed around 4:30 p.m. as a result of the mudflows. Mud flowing across Palisades Drive in the Pacific Palisades caused another shut down north of Sunset Boulevard in an area already hit hard by the Palisades Fire weeks ago.

Storm-triggered mudflows prompted several road closures Sunday afternoon as the region remained under a flood watch.

Overnight and morning rain loosening up the dirt and rocks on the hillsides caused problems for accessing these areas.

Video from AIR7 showed the mudslide on Grand View Road in Topanga. State Route 27 is fully closed in both directions between PCH and Grand View Drive.

Northbound PCH at McClure Tunnel and southbound PCH at Sweetwater Canyon Drive are also closed. An additional hard closure immediately west of Topanga Canyon Boulevard is also in effect due to mudflows.

South of Mullholland Drive to Grand View Drive is closed except for residents with ID.
