Entry from Mexico is surprisingly limited given the length of the region's Mexican border. New Mexico has border crossings at Santa Teresa, Columbus and Antelope Wells, of which the small town of Columbus is the only 24-hour port of entry; most traffic entering New Mexico from Mexico arrives via the 4 border crossings at El Paso, Texas, just outside the state. Arizona has border crossings at Douglas, Nogales and (outside) Yuma, with a few others that may or may not be open at any given time.
Major highways entering the region from other parts of the United States all have their western entries to the region from California (note that produce brought into California from Arizona is subject to inspection). East- and north-side entry points are:
I-25 (north end), I-70 (east end) and I-80 (east end) are all subject to occasional delays or closures in the winter owing to snowfall, as they go over mountainous country en route to (and within) the Southwest.
