Just as I suspected: the “NAFTA Superhighway” is much like Anthropogenic Global Warming. It’s probably not really happening, and if it were, it would probably be a good thing.
Bump and Ping!
Previous threads on this topic have noted a point of confusion: the Trans-Texas Corridor is not the same thing as the "NAFTA Superhighway". The former is a concept that some would like to see built, but the latter already exists in the form of a network of existing Interstate highways.
As for whether a realignment of our cargo transportation network away from the west coast and favoring Mexican ports is a good thing for us, I don't see what benefit can come of it. I'm certain that it benefits Mexico, no matter what the impact is in the U.S.
