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 (20,820 liters) 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 had reopened around 6:15 a.m., but aerial video indicated the spill had left a mark.

WSB-TV reports that traffic was still backed up to Smyrna.

It�s unclear whether anyone was injured or to whom the ink belonged.
