FEDERAL WAY, Wash. (KOMO) — A tractor-trailer made a fowl mess when it rolled over on northbound I-5 near Federal Way Wednesday morning.

It dumped about 40,000 pounds of chicken feathers across the freeway.

Trooper Rick Johnson says the driver told investigators he fell asleep at about 3:30 A.M. and lost control of the truck, which hit a guardrail and overturned.

Traffic was backed up for eleven miles during the morning commute.
