MORRIS, Ill. (AP) — Traffic's backed up in northern Illinois after a trailer loaded with 14 tons of double-stuffed Oreos overturned, spilling boxes of cookies into the median and roadway.

Illinois State Police Sergeant Brian Mahoney says the truck's driver was traveling on I-80 near Morris around 4 a.m. Monday when he fell asleep at the wheel and slammed into the median, spilling some of the 28,000 pounds of treats.

The crash about 50 miles southwest of Chicago remains under investigation.

Mahoney says no charges have been filed but both lanes of traffic remain closed while authorities remove the cookies.
