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
  • Longer rural roads classified as "Major Collector" on the FC map should be set to  Minor  rather than  PS  to avoid pruning of valid routes.
  • State highways that are classified on the State FC map as "Minor Collector," but are dirt/gravel, should be set to  PS  and have the unpaved box checked, instead of  Minor .
  • SR-26, Hatch NM to Deming NM, is set to  Major  to allow routing from I-25 south to I-10 west and bypass Las Cruces.
  • Paseo del Norte, Eagle Ranch Rd NW intersection to I-25, is set to  Freeway  due to meeting the requirements as one.
