SISKIYOU COUNTY — Ice on the roadway caused at domino-effect crash involving at least 60 vehicles along Interstate 5 on Tuesday night, leaving a string of disabled cars a mile long and forcing the closure of both directions of the interstate, a spokeswoman for Cal Fire said.

Fire crews have set up a command center for victims, who reported only minor to moderate injuries. No one was killed in the crash, which was reported about 6:30 p.m., said Cal Fire spokeswoman Suzi Brady.

Brady said damaged vehicles are lining the interstate for one mile between Yreka and Hornbrook in Siskiyou County. The highway is closed in both directions around the crash area. Brady said “extreme ice conditions” caused the collision.

There is no estimated time of reopening.
