Authorities in Winnebago County say road conditions were a likely factor in a fatal two vehicle accident early yesterday morning. It happened just after 3:30 on Highway 41 northbound on the causeway over Lake Butte des Morts. A 36 year old Omro man heading north lost control, hit the median barrier, crossed over all three lanes, and smashed into a semi. The Omro man was dead at the scene, while the Iron Mountain, Michigan, man driving the semi was not hurt. Authorities say speed and road conditions were factors in the crash. The victim’s name has not been released.
