After seeing these vast and endless stretches of barrels I've come to the conclusion that the INDOT (Indiana Department of Transportation) doesn't have a warehouse. I think they're storing the barrels right there on the highway. When they actually need some barrels they just drive over to the highway, load a few hundred in some trucks and off they go. When they're done they bring 'em back and store them on the highway at the pretend worksite again. It's the only explanation that makes sense.
