“It's suspicious, but it's undetermined at this time what the cause was,” Woodard said.
The fire chief said winds carried the smoke from the sizable fire away from the interstate and there was no problem with visibility for passing motorists.
Fire Battalion Chief Brian Stanaland said he saw the fire before dawn while driving along the interstate to work.
“The smoke went pretty much straight up in the air. We didn't have a lot of wind blowing,” Stanaland said. “It was a big fire.”
A phone call to the motel was not answered Thursday afternoon.
