An early morning crash involving a bus and a tractor trailer shut down westbound Interstate 20 traffic in Carroll County, Ga., for more than three hours Wednesday.

According to Tracey Watson, public information officer for the Georgia Department of Public Safety, the tractor trailer rear-ended a bus in the right-hand westbound lane at mile marker 21 near Villa Rica. Watson said the vehicle rear-ended was not a school bus. Both vehicles traveled off the road onto the right shoulder, overturned and caught on fire.

Both drivers were injured in the crash. The driver of the bus was transported to Tanner Medical Center in Villa Rica and the driver of the truck was airlifted to Grady Hospital in Atlanta.

As of 9:30 a.m. Eastern time, the left lane of westbound traffic had been reopened, while the right lane remained closed between mile marker 20 and 24, Watson said.
