Interesting...after looking at Wikipedia and seeing that it supposedly existed along that road in the past (although it was longer then), I checked some older official Indiana maps and noticed that it disappeared in 2000. Looking at
the 2016 official map, there's nothing mentioned there, although the map scale doesn't even allow for such a short road to show up. However, the
INDOT GIS shows it. Maybe it's back from the dead?
In case cabiness42 happens to check this forum, it would be helpful to know if the signs appeared relatively new.
