NM460 is signed north-south, so it should have its point order reversed.
The TX/NM label can stay as-is.
Can't speak to that route specifically, but NM has many routes milemarked north to south, with our waypoints ordered accordingly. Similar with Alaska and neighboring jurisdictions, where mile (km) 0 for the Alaska Highway is in British Columbia, and some other routes have an east to west waypoint order.
I would go no-build on such routes, the waypoint order is harmless (at worst) to our users.
