One person was killed in Indiana when at least 20 vehicles piled up amid heavy fog on a highway east of South Bend. Numerous others were injured.
The National Weather Service had issued a dense fog advisory for the area, saying visibility could be less than a quarter mile.
A total of 114 vehicles were involved in pileups in the eastbound lanes, while between 80 and 100 vehicles crashed in the westbound lanes, the sheriff's department said.
At least eighteen people were being treated Wednesday evening at a hospital in Lansing. State police closed a 12-mile stretch of the highway in both directions following the accidents. The eastbound lanes were reopened late Wednesday, but the westbound lanes remained closed.
The chain-reaction collision in Indiana left wrecked vehicles scattered in both directions over a three-mile stretch of the Indiana Toll Road. Police closed a 43-mile stretch of the highway for more than six hours.
At least seven injured people were treated at hospitals in the Indiana crashes.
