So far, it looks like a hoax to me.

Corsi's Track Record

Corsi is a renowned conspiracy theorist who says that George Bush is attempting to create a North American Union (we looked at that here) and that there is evidence that the World Trade Center may have collapsed because it was seeded with explosives. More recently, Corsi claimed that Obama released a fake birth certificate. We've debunked that twice now. And, as our colleagues at PolitiFact.com found, many of the themes in "The Obama Nation" are reworked versions of bogus chain e-mail smears.

According to Paul, a secret organization run by unaccountable government figures is in league with foreign corporations who are all bent on usurping American sovereignty. That's not from the script for a new X-Files movie. (Or not that we know of.) It's the gist of Paul's description of a supposed "NAFTA Superhighway." Paul describes it on his Web site as "a ten-lane colossus the width of several football fields, with freight and rail lines, fiber-optic cable lines, and oil and natural gas pipelines running alongside." And that's not all. According to Paul, the ultimate plan is to form a North American Union with a single currency and unlimited travel within its borders, all headed up by "an unholy alliance of foreign consortiums and officials from several governments" that together form the shadowy "quasi-government organization called the 'Security and Prosperity Partnership of North America,' or SPP."

The problem with Paul's claim is that there are no plans to build a NAFTA Superhighway. Or a North American Union, for that matter. And while the Security and Prosperity Partnership of North America does exist, it's just a boring bureaucracy.

Like many conspiracy theories, this one is a mixture of fact and fiction. improvements to existing roads, but is not lobbying for, or planning to build, any new thoroughfares. From the NASCO That scary-looking map, with lines that rumor suggested were drawn to scale, is the product of an actual group called North America's SuperCorridor Organization (NASCO), which is a consortium of public and private entities. But contrary to conspiracy theorists, the map does not show a new highway. Those bright blue lines show only I-35 and I-29 – interstates that already exist. On its Web site, NASCO says it and some of the local governments along I-35 have been referring to that route as the "NAFTA Superhighway" for years.

    NASCO: "NAFTA Superhighway" - As of late, there has been much media attention given to the "new, proposed NAFTA Superhighway". NASCO and the cities, counties, states and provinces along our existing Interstate Highways 35/29/94 (the NASCO Corridor) have been referring to I-35 as the 'NAFTA Superhighway' for many years, as I-35 already carries a substantial amount of international trade with Mexico, the United States and Canada. There are no plans to build a new NAFTA Superhighway - it exists today as I-35.
