The Morton Fire Department responded to a fire early Monday morning at the Yellow Freight terminal located at 780 W. Birchwood, Morton.

Firefighters were called at 1:06 a.m. when a police officer noticed a semi-tractor on fire next to the building. Firefighters arrived to find that the fire had extended to a second parked semi-tractor and to the outside of the building.

Firefighters were able to quickly extinguish and keep it from continuing into the building.

The fire destroyed the two semi tractors and caused some damage to the outside of the building.

 There were no injuries reported. The total damage is estimated at $85,000. A private hazardous materials clean-up crew was at the scene at 9 a.m. Monday cleaning up any diesel fuel or engine fluids that may have leaked from the semi tractors. The cause of the fire remains under investigation, but is not considered suspicious.
