The highway travels northeast and passes an electrical substation before an intersection with US 64 on the south side of the Rio de Tierra Amarilla, which it crosses before entering the community of Tierra Amarilla.

In the northern outskirts of Tierra Amarilla, the highway intersects NM 573 where it turns northwest.

The roadway continues through open land with a few houses before reaching its northern terminus at concurrent US 64 and US 84 north of Tierra Amarilla.
