It’s an open secret in NM that the roads are shoddily constructed by low-bid govt cronies, who will get the contracts in a few years to repair their own mess. The land of enchantment is really the land of orange cones and detours.
Based on a couple of decades of vacation experiences in NM a couple of decades ago, the place seemed to be a very large Texas State Park.
As such, Texas should be funding the roads...
