Sixty-five people, many of them Burke County Middle School students, were treated for injuries at local hospitals Saturday after a chain collision involving six school buses and a passenger car on I-20 westbound near mile marker 98.

One school bus driver Angela Anthony, 44, of Midville, Ga. was airlifted to Grady Memorial Hospital in Atlanta for treatment for serious injuries, according to Georgia State Patrol spokesman Gordy Wright. Anthony had to be cut from the wreckage.

Georgia State Patrol said as the buses slowed, one bus struck the rear of another setting off a chain reaction crash. A passenger car was the last vehicle in line and struck the rear of the last bus.

The students were headed to Six Flags over Georgia as a reward for performing well on the CRCT.

The students were from Burke County Middle School in Waynesboro, according to officials at the scene.

Fifty-six students were sent to local hospitals to be treated, said Amy Nunnally, spokeswoman for the Burke County School System. The Georgia State Patrol reported that 65 were injuried in total.

I-20 Westbound was completely blocked off at Exit 98 for several hours while officers directed traffic off of the interstate. Highway 278 was back up as well from those trying to avoid the accident.

The wreck occurred around 11 a.m. The wreck was cleared just after 4 p.m.

Morgan County sent several buses to the scene to help transport uninjured children.

The crash remains under investigation by the Georgia Sate Patrol in Monroe and the Specialized Collision Reconstruction Team.
