Interstate 5 in Siskiyou County has reopened this morning in both directions after a crash involving about 60 vehicles.
California Department of Forestry and Fire Protection spokeswoman Julie Hutchinson said a number of people suffered minor to moderate injuries in a series of crashes that started around 6:30 p.m. Tuesday and stretched for nearly a mile along the northbound side of the freeway, according to the Associated Press.
Hutchinson says she doesn't know the exact number of people injured. The southbound side of the interstate was closed so emergency vehicles could reach the scene.
It's not known what caused the pileup, the AP reported. But Hutchinson says stretches of the roadway were icy. The National Weather Service has issued a winter weather advisory for the area.
The crashes took place near Yreka, just south of the Oregon border, or about 250 miles north of Sacramento.
