PREVIOUS UPDATE: A tractor trailer overturned on westbound I-24 Wednesday. The 18-wheeler was hauling five other vehicles that also flipped into an embankment off the interstate.

Authorities were dispatched to mile marker 141 just after 4 a.m. EST for reports of a single vehicle crash with entrapment.

Sgt. Bailey said the company involved is 5J Transport a company based out of Zion, Illinois.

Crews spent several hours working to clear debris and remove all five car.

Traffic was reduced to one lane on I-24 Westbound for a couple of hours. Wreckers have removed all five the cars, but are still working to pull the semi out of the embankment.
