A tractor-trailer hauling potassium hydroxide south on Interstate 75 hit a disabled van in Monroe County early Monday, closing the highway for about four hours near Johnstonville Road.
Chief Ronald Norris of Monroe County Emergency Services said the truck flipped on its side, and the motor dislodged from the cab and caught fire off the right side of the road shortly after 1 a.m.
Macon-Bibb County’s Hazardous Materials Unit inspected the wreckage to make sure none of the chemical was leaking, said John Malcolm, a district chief for the Macon-Bibb County Fire Department.
When it was determined nothing was leaking, the interstate reopened at about 5 a.m.
Never miss a local story.
A wrecker arrived at about 8 a.m. as crews were working to offload the chemical so the trailer could be uprighted and removed.
Norris said the highway was clear by about noon.
The truck driver was taken to The Medical Center of Central Georgia with injuries but was back on the scene later in the morning, Norris said.
No one was inside the van at the time of the accident.
