According to Georgia Department of Transportation (GDOT), an overturned tractor-trailer spilled 7,500 gallons of diesel fuel on Interstate 285 westbound at Jonesboro Road.
The driver was taken to Grady Memorial Hospital with minor injuries.
The crash blocked traffic in all directions for hours in the midst of the Tuesday morning rush hours. All lanes reopened just before 9 a.m.

When crews arrived at the scene around 3 a.m., they found the tractor trailer was spilling it's 7,500 gallons of diesel fuel all over the roadway but no waterways or drains were impacted from the spill.
Atlanta Fire and Rescue Battalion Chief Stephen Hill said clean up crews were able to capture about 3,000 of the 7,500 gallons that spilled. About 4,500 gallons were lost to the environment.
"They captured as much fuel as they could to keep it from going off to some other part of the environment," Hill said.
Hill said they dug a ditch and built a dam to hold the fuel as it left the truck. Clean up should take most of the day.
Clete Barton, an on-site coordinator with the Georgia Environmental Protection Division, said the quick action by the Atlanta Fire Department and the good luck of being away from waterways minimized the impact of the spill.
Barton said the trucking company paid for the cleanup by contracting with a business specializing in environmental clean-up. They excavated the diesel fuel by using absorbent sand and a street sweeper.
Contaminated soil from the median was removed. Barton said he's confident the area was adequate cleaned after the massive spill.
