A truck carrying 40,000 pounds of printer ink overturned on an Atlanta interstate, closing all lanes on an outer loop for four hours…that’s 5,500 gallons of ink.

News outlets report a car cut in front of the truck around 2 a.m. Wednesday, causing the truck to lose control and crash.

Atlanta Police’s Traffic Report Twitter account says the spill stained Interstate 285, just south of Interstate 20.

All lanes on I-285’s outer loop were closed while crews used sand and dirt to soak up the ink. Southbound lanes reopened around 6:15 a.m. but aerial video indicated the spill had left a mark.
