GIS Legend

The New Mexico Classification and Color scheme comes from the official New Mexico D.O.T (NMDOT) Functional Classification (FC) map that is published by NMDOT. The legend shows what classifications NMDOT uses and what color is assigned to each class. The actual interactive State Map can be found here:

Deviations from FC
  • State Highways that are classified on the State FC map as "Minor Collector," but are dirt/gravel, should be classified as  PS , instead of  Minor .
  • SR-26, Hatch NM to Deming NM, as  Major  to allow routing from I-25 south to I-10 west and bypass Las Cruces.
