Semitruck hauling 31,000 pounds of rotisserie chickens causes grass fire near Strasburg

STRASBURG, Colo. -- A semitruck carrying 31,000 pounds of rotisserie chickens malfunctioned on Interstate 70 early Tuesday morning, causing a minor grass fire, the Colorado State Patrol said.

The truck caught fire after 2 a.m. and it spread to nearby grass, officials said.

Westbound Interstate 70 was closed at the Strasburg exit as crews worked to put out the fire. The grass fire was contained to about three acres, the Strasburg Fire Department said.

The detached trailer was involved, but crews worked to get out the fire. The interstate has since reopened.

The truck driver was not hurt and no other injuries were reported, officials said.

The cause of the malfunction is under investigation.
