Authorities say several crashes involving about 50 vehicles on Interstate 5 north of Los Angeles have sent 12 people to the hospital.
The Grapevine section of the interstate was closed as emergency crews responded to the accidents Saturday afternoon.
The California Highway Patrol’s traffic incident website said the accidents occurred amid thick fog.
Los Angeles County Fire Capt. Ron Haralson said a dozen people were transported to the hospital. One was in critical condition, four others sustained minor injuries and seven more had minor injuries. The injured included a 21-month-old child and a horse in trailer that was rear-ended.
The Grapevine carries traffic over mountains between greater Los Angeles and the San Joaquin Valley. The wrecks caused traffic on northbound and southbound lanes to back up for miles.
