History
The section occupied by modern day NM 182 was initially built in 1950 as a portion of NM 273 connecting La Union with El Paso. In the late 1990s to early 2000s this stretch was removed from NM 273 and was designated as NM 182. After the split, the length of the highway was 2.033 mi and the road extended to NM 416 (Casad Road) down Alvarez Road. After NM 416 was decommissioned in mid-2000s NM 182 was shortened down to its current length and rerouted away from Alvarez Road.
