Prior to 1981, US 191 was a single, continuous route. But in June of that year, a big change was approved for US 191: the route was extended south to Chambers AZ via what had been US 187 through Wyoming. In order to get there, US 191 was assumed to follow an implied route through Yellowstone National Park. However, since US routesdo not exist in Yellowstone, this action created two separate, disconnected segments of US 191. This page covers the south segment, the northern terminus of which was (and still is) at thesouth entrance to Yellowstone.

 c. 1983, Rand McNally | That map makes it clear why it did not make sense to have US 191 headingnorth from I-40, while just six miles to the east it was US 666 headingsouth from I-40. Plus, Arizona was probably eager to be done with chronic US 666 sign replacements due to frequent theft. So in 1992, US 191[s] was extended east from Chambers along I-40 to Sanders, and then south, replacing what had been US 666 all the way to Douglas... or at least close (photos and more info on theDouglas page). |
