(Cass Co., ND) — There were no injuries but plenty of cleanup after a semi towing a grain hopper overturned in Cass County. The State Highway Patrol says the semi was eastbound on Interstate 94 early this morning when the truck veered off the highway and into the median where it hit a cable barrier and rolled over. A load of sunflowers was spilled. Troopers say it appears the driver fell asleep but their investigation is ongoing.
