It passes by a cemetery before traveling straight through the center of the community of Piney, with the highway serving as Main Street. PTH 89 enters a wooded area as it has a junction with PR 201 before coming to an end at an intersection with PTH 12 (MOM's Way), with the road continuing north towards Badger as PR 203.
