Part of Interstate 75 in Madison County had to be closed early Thursday morning after a tractor trailer flipped.
Police say the truck was traveling south near the 95 mile marker, when it went off the right side of the road.
Police say the driver then woke up, overcorrected and flipped the truck.
The truck was carrying an unknown chemical, which did not spill.
The driver, Ted Nason, of Doylestown, Ohio, had minor injuries.
