A semi carrying medical waste turned over on its side Monday and closed northbound/westbound I-94 at Highway K for a few hours.

DOT cameras captured the scene shortly after it happened, and The Journal Times reported the driver of the truck hit the right rail, causing the trailer to turn over. No one was injured.

All northbound lanes of I-94 were closed while authorities made sure the medical waste was properly contained before righting the semi and re-opening the expressway.

Traffic was allowed through by 6 p.m., the story continues.
