A tractor-trailer hauling 5,500 gallons of printer ink overturned Wednesday on the Westside Perimeter, spilling its cargo onto the interstate and causing delays for the first half of the morning drive.

All lanes of the I-285 outer loop were shut down for several hours after the big rig overturned before Martin Luther King Jr. Drive. Southbound traffic was diverted onto Hollowell Parkway, and the ramps from I-20 to I-285 South were also shut down, according to the WSB 24-hour Traffic Center.

Atlanta police said there was a “large amount of ink spilled on the roadway” when they responded to the wreck around 2 a.m.

“The driver of the overturned vehicle advised that he was attempting to avoid another vehicle when he lost control of the tractor-trailer, which flipped onto its side,” police spokesman Officer Jarius Daugherty said.

No one was injured, and the crash remains under investigation.

Fire crews that responded to the scene spread dirt and sand to absorb the mess.

While the interstate has reopened and traffic has since recovered, a large ink stain remains. There are no longer delays associated with the crash, according to the Traffic Center.
