In virtually every case I've seen in this state where the road map shows a state highway but there's no physical signage for it, the highway has most likely been removed from the State Highway system, therefore no longer exists. This highway is a little different, in that the road maps have never shown it, and to the best of my knowledge it has never been signed. The only place where I've seen its existence is on a county highway map supplied by the Oklahoma Department of Transportation. And since they should know where their own highways are...

Western Terminus: Main St., Owasso

Looking east along 2nd Avenue, and the unsigned highway, which begins at the intersection in the foreground.
