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.

NM 162 was created in the 1950s, after US 84 was moved onto a new alignment west of Tierra Amarilla. NM 162 originally turned in Tierra Amarilla and followed the current NM 573 north to  the current NM 512. It then turned west and followed the current NM 512 west towards US 64 and US 84 north of Brazos. In the 1988 renumbering, NM 512 and NM 573 were created and NM 162's northern terminus was changed to its current location.
