(Radio Iowa) – A familiar pit stop for motorists traveling along Highway 20 near Rockwell City was reduced to rubble in a massive fire Tuesday. Multiple media outlets report a semi parked at the pumps right beside Sparky’s One Stop caught fire and the flames quickly spread and engulfed the building. The convenience store burned to the ground and is a complete loss with damage estimated around five-million dollars.

The truck driver was hospitalized and treated for smoke inhalation but no one else was hurt. Investigators are working to determine what caused the truck to catch fire.
