- US-550 Farmington to Albuquerque
- US-285 Colorado to Texas

- SR-26 Hatch NM to Deming NM, critical for functional classification routing
Functional Classification
Reference: Road names/USA and Road types/USA. New Mexico participates in the functional classification of roads; however, this is a new standard that is going through changes and all changes should be socialized with existing primary editors in the state.
New Mexico's functional classification is not completely clear. Reference to the Federal Functional Classification can be found in THIS MAP (which has low resolution) which is on NMDOT's Planning Page.
Functional Classification of roads is adjusted specifically to accommodate certain routing issues within New Mexico. Therefore do not change functional classification of roads without socializing with the Waze Community in New Mexico. These roads have had special research and testing to optimize routing:
- SR-26, Hatch NM to Deming NM, as Major Highway to allow routing from I-25 south to I-10 west and bypass Las Cruces.
