The route is the main street for Joseph, Monroe and Richfield and spans 24.14 miles (38.85 km).

The road enters Joseph as Main Street and turns northeast after exiting the town.

The road now heads east-northeast before turning southeast and eventually east as the highway traverses the hills that separate Joseph and Monroe.

Exiting Monroe and entering rural surroundings, it veers slightly eastward, passing through the community of Austin.

The route continues in this direction in a rural environment before terminating at SR-24 north of Sigurd and southwest of Salina.
