Driver likely fell asleep behind wheel in interstate crash that injured 4, officials say

WINDSOR, Wis. — Four people were taken to the hospital following a crash on the interstate early Friday morning near Windsor.

Wisconsin State Patrol troopers were dispatched to the southbound lanes of I-39/90 between County Road V and Highway 19 around 3 a.m. This is near Mile Marker 129 and just outside of Windsor.

One vehicle was involved in the crash. Troopers said the crash remains under investigation, but they suspect the driver fell asleep at the wheel.

Of the four injured, two were airlifted from the scene. Their injuries are serious, but not considered life-threatening, according to the Wisconsin State Patrol. Troopers said the group was from out of state and headed on a trip. They are reminding drivers to rest up before long trips.

All lanes were briefly closed overnight, but northbound traffic reopened at about 4:30 a.m. Southbound traffic reopened just before 6 a.m.
