A 4 a.m. wreck closed two lanes on Interstate-75 South near Sardis Church Road and Highway 49 Thursday morning.
The lanes were reopened at 7 a.m.
Bibb Sheriff's Office spokesman Sean DeFoe said the wreck started when a woman attempted to merge on I-75 South in her Ford Taurus from the Sardis Church Road exit.
She clipped a tractor-trailer which caused her to spin, hitting a cement truck, Defoe told Eyewitness News.
The Taurus got hung up on the cement truck and dragged about a mile before catching fire near the Bibb-Crawford county line.
DeFoe said the drivers of the trucks and the driver of the Taurus were taken to the hospital with non-life-threatening injuries and released.
All lanes are now open.
