SR 192 begins at an intersection with US 1/SR 4 just north of Oak Park.

It heads east into Stillmore, where it intersects SR 57 (2nd Street).

Then, it turns north and curves to the northeast until it enters Twin City.

SR 192 continues to the north and curves to the northwest until it meets its southern terminus at SR 56 (Covena Road) in Summertown.

At least as early as 1940, this roadway was established as part of the SR 192 mainline.
