(KMOV) -- An overturned tractor trailer on Interstate 44 in Fenton caused a traffic nightmare during Thursday morning's rush hour.
Officials say the accident happened on eastbound I-44 just past Antire Rd. around 11:45 p.m.
There were no other cars involved and the driver of the truck was not injured.
One eastbound lane of the interstate remained closed Thursday morning while crews worked to unload the semi-truck from the scene.
Traffic at one point was backed up about seven miles to almost Highway 109 in Eureka. It was not immediately known when the interstate would fully reopen.
The cause of the accident was not known.
