^Looking south from the northern end at Illinois 14 in Mulkeytown, February 2023.
Illinois Route 184 is a very short north-south route in Franklin County, which parallels Illinois 148 to the west. It connects Illinois 14 to Illinois 149 without any intermediate junctions.
Illinois 184's northern end is at Illinois 14 at Mulkeytown, a place just west of Christopher. (An old picture from 2008 is also included, at the bottom.)
