Freezing rain caused hundreds of accidents and nearly 900 calls of service late Saturday into early Sunday, the state patrol said.
"It was one for the ages as far as road conditions go," State Patrol Lt. Eric Roeske said.
There were 438 reported accidents, the state patrol reported at noon Sunday. From those accidents, 376 of them were in the metro area, the Star Tribune reported.
Sidewalks were also very dangerous as many pedestrians fell causing head injuries, sprained ankles, broken bones and fractures.
"Until you start sliding, you can't really distinguish the ice from the wet roadway," Roeske said.
According to the Pioneer Press, it was difficult to get the salt trucks on the road initially, and once they were out it was still a challenge to prevent them from going into the ditch.
