I looked @ old GSV, @ US-70 Bus, it's always only been signed for 'SOUTH' there back to
2007.
However, due to the signage always being there @ College/US-70, & lacking the 'TO' back to
2007, I would support at least adding a 'ColSt' point to US-70's file in case somebody needed it due to following those signs to get to actual TN-266.
