A fire destroyed four trailers at a trucking terminal in Mahoning Township Wednesday night.

It was the second fire this month at Estes Express Lines at 457 Mahoning Dr. East.

Mahoning Valley Fire Chief Mark Ebbert said firefighters were dispatched at 7:35 p.m. and two trailers were on fire when they arrived.

Ebbert said the fire quickly spread to two more trailers, destroying all four, and that items on the loading dock were also damaged.

There was also a fire at the terminal on Aug. 11, in which a building and several trailers were damaged.

Ebbert said it took about two hours to contain Wednesday’s fire, with the last personnel leaving the scene at 2 a.m. Thursday.

He said employees were evacuated from the building and that no one, including fire personnel, were hurt.

Ebbert said the cause of the fire is unknown, and that a state police fire marshal and Mahoning Township Police Department are investigating.

The Lehighton, Franklin Township, East Penn Township, Bowmanstown, Parryville and Jim Thorpe fire companies responded, as did Lehighton and Mahoning Valley ambulance.

“The important thing is nobody was hurt,” Ebbert said. “All the first responders worked well together.”
