Interstate 40 New Mexico Descriptions

I-40 used to have a conventional mileage sign in New Mexico to the east of San Jon (a village to the east of Tucumcari, New Mexico) which probably bore the longest distance on such a sign. The sign showed 1007 miles for Los Angeles,[4] although I-40 doesn't actually go there (it is accessed via Interstates 15 and 10).

Numerous roads throughout the state connect directly to the interstate in violation of Interstate Highway Standards.
