Lost America has a neat collection of "night photography of the abandoned West." This one above is the original Highway to Hell, route 666 in Utah:
Sunset on U.S. Route 666 in southern Arizona. Redesignated as U.S. Route 491 in 2003 from pressure by Christian groups and an AZ highway department tired of replacing stolen signs.
Another Highway to Hell previously on Neatorama.

Or is it even real at all?
