Patch has gotten word that a male driver going north on I-94 Saturday night went over the side of the expressway and ended up on the East Frontage Road.
Early reports indicate the accident happened between 7:45 and 8 p.m. just north of the Highway KR exit.
The man may have suffered a black out, causing him to lose control of his car. Police and rescue responded, and the man was transported to Wheaton Franciscan St. Mary's for a head injury.
Traffic on I-94 was not interrupted and no one else was involved in the accident.
Patch will update this story as more details become available.
