The photo below is looking into Yellowstone National Park, approaching from
West Yellowstone MT:

That was the original north end of US 191. Then, for a brief period during
the early 1980's, it was the south end of US 191. Today it's the south end of
the northern segments of both US 191 and US 287 (which both resume at the South
entrance), as well as the east end of US 20's western segment (which resumes
at the East
entrance). Below we're looking the opposite direction, at the point where
all three of these routes are signed for the first time west of the Park:
Elbert, July 2005
The three routes are co-signed for only a short distance before they go their
separate ways.
