Route description
The clockwise (southern) terminus of SR 73 is located at a junction with US 60 southwest of Show Low. From this intersection, the highway heads southeast within the Fort Apache Indian Reservation. It passes through Cedar Creek and curves towards the east before passing through Canyon Day. Continuing towards the east, it reaches Fort Apache, where it turns towards the northeast. It continues to the northeast on to Whiteriver, where it begins to head towards more of a northerly direction. It continues north through the Fort Apache Indian Reservation until it reaches its counterclockwise (northern) terminus at a junction with SR 260 east of McNary.
