The Grapevine near Castaic was closed around 5 a.m. Saturday due to snow. People tried alternate routes to get around the closure, but dozens of vehicles - many of them following Google Maps - ended up stuck in mud in a riverbed.
"We didn't see it," said Wayne Nash. "We just listened to what Google said. It said turn this way and save two hours. I thought it was smart enough not to send you through a river bed."
The freeway reopened by 9 a.m. after California Highway Patrol officers checked road conditions.
The 15 Freeway through the Cajon Pass was covered with sand early Saturday to help cars drive through the icy conditions on the road.
The storm started Friday evening and into the overnight hours, drenching the Southland with heavy downpours and some winds. Streets were flooded and the steady bouts of rain caused low visibility and slick roads.
According to the California Highway Patrol, there were 148 crashes in Los Angeles County just between 6 p.m. and 10 p.m. There were also about 30 crashes in Orange County during the evening.
