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 2009
The three routes are co-signed for only a short distance before they go their separate ways.
