The bus had been one of three buses (purchased by Yukon Construction with funds given to them by the State of Alaska) to house workers who were building roads. Eventually, two of the dilapidated buses were taken back up to the highway, but it was decided that the third would remain as shelter for hunters and trappers. A lot changed about the landscape over the years, but the old bus remained where it was abandoned.
The construction workers were housed in converted buses parked alongside the road, each fitted with beds and a stove. The road was never finished due to problematic weather and one of the buses was left behind for hunters to use if lost.
