Crews responded to a commercial truck that caught fire west of Richmond at about noon Wednesday, according to scanner traffic.
Firefighters were paged out to State Route 142 near Mile 16 on the report of an articulated dump truck owned by Christensen Construction that was going up in flames, and crews closed the highway near the scene. The flames had been extinguished within 20 minutes of the first report, and firefighters from Smithfield and Richmond continued working at the scene until about 1:20 p.m.
Cache County Fire Marshal Jason Winn said no one was injured in the fire. The truck was actually being towed by another dump truck so mechanics could work on its transmission when the fire started, Winn said. The engine was running and a driver was in the cab to steer the vehicle as it was being towed, according to Winn, but after the fire started the driver got out without apparent injury.
Winn said the fire appears to have started in the cab area, and early damage estimates are about $70,000.
The fire and its cause are still under investigation.
