Piles of gravel covered Victory Drive near the Interstate 185 exit.
Military police blocked off the section as crews worked to clear up the road.
Officials say the driver of the 18-wheeler was heading toward the Harmony Church area when the truck's weight shifted causing it to land on its side spilling tons of gravel on the road.
The driver was a Fort Benning contractor. He was taken to the hospital for minor injuries.
The gravel was for the construction site of the new Armor school.
