Washington State Patrol Trooper Guy Gill said the animal parts fell from the truck Thursday night and spread across two lanes of northbound Interstate 5 near Joint Base Lewis-McChord when the truck driver slammed on the brakes to avoid hitting slow-moving traffic ahead, KOMO-TV, Seattle, reported Friday.
"I know this doesn't look good but trust me, it smells even worse!" Gill posted on Twitter.
Traffic was directed around the affected lanes while a front-end loader was brought in to clean up the animal parts, troopers said.
Gill said the driver will be issued a citation for failing to secure the load.
