For the moment you will have to take my word for it that I have taken U.S. Route 460 from Southern Illinois to Norfolk, Va. I am not able to find you a suitable map online, but the route is now replaced with I-64, a fact you may research yourself.
But as a parallel example, I offer: http:
IIS 10.0 Detailed Error - 404.0 - Not Found where a group is trying to preserve the old federal highway known as Rte 40, which I have taken from Cumberland, Maryland west to Terre Haute, Indiana. This route was largely replaced by I-70.
