5 Freeway Closed Through Grapevine as Snow Causes ‘Major Traffic Problems’

4

The 5 Freeway was shut down at the base of the Grapevine Thursday morning as a storm blanketed the mountainous area with snow, creating dangerous conditions for vehicles trying to pass through the major throughway.

All northbound lanes of the 5 are closed at Parker Road in Castaic, while southbound lanes are shut down at the base of the Grapevine, according to the California Highway Patrol.

CHP dubbed the SigAlert, “Operation Snowflake.”

Earlier, Caltrans had warned that the snow was causing “major traffic problems” in the Grapevine and Lebec areas along the interstate, with vehicles sliding across the snow-slicked road.

The National Weather Service tweeted out a Caltrans image of the Tejon Pass, showing the 5 Freeway at Frazier Mountain covered in a layer of fresh white powder around 10 a.m.; the agency also warned of “major travel impacts” in the area.

By 1 p.m., the traffic backup extended for miles, with motorists appearing to be stopped just ahead of an exit ramp in Gorman, Sky5 video showed.

One motorist said he had been stuck in traffic related to the closure for some three hours, though he noted the traffic was “slowly improving” as of 11:20 a.m.

Forecasters had earlier warned that a storm system bringing heavy rain to much of Southern California could bring as much as 6 feet of snow to elevations above 6,500 feet.

By 9:30 a.m., some 4 inches had fallen in Frazier Park, the weather service reported.
