Proof that it is actually happening. Meetings in Texas with government officials.

YouTube - Ron Paul On Lou Dobbs About NAU Super Highway Feb.19.2008 (part 1)

YouTube - Lou Dobbs Tonight NAU Super Highway Part 2 Feb.20.2008 (part 2)

Ron Paul and Lou Dobbs saying something does not constitute proof. It's a conspiracy theory with no basis in fact.

Watching the Part 2 shows the people in meetings being held. Newspaper articles in Texas are covering the meetings.
Conspiracy theory ..tell that to the people that are being told to their face that they will lose their property.

Here is a link that is "not" from Lou Dobbs
A local news story from Waller County

They are building a highway through the center of the country. These type of projects require land and the government condemns the land they need. It's nothing new.

Ron Paul also subscribes to the notion that this highway is evidence of a secret government plan to merge our 3 nations. It's absolute hooey.

I only said the word "superhighway" ..people have been lied to for years by the state government that this was not in the works. It takes years to come up with these plans..not months.

Interstate and International Trade Corridors

Ports-to-Plains Trade Corridor

The Ports-to-Plains Trade Corridor is a proposed divided highway corridor stretching from Laredo through West Texas to Denver, Colorado. Designated as a High Priority Corridor by Congress in 1998, the Ports-to-Plains corridor will facilitate the efficient transportation of goods and services from Mexico, through West Texas, Oklahoma, New Mexico, Colorado and ultimately on into Canada and the Pacific Northwest.

Together, the communities along the Ports-to-Plains Trade Corridor are becoming the gateway to trade throughout the nation and with Mexico and Canada. The Ports-to-Plains Trade Corridor will provide a vast number of benefits for communities along the corridor. It will:
allow for the development of less congested ports of entry along the Texas-Mexico border.
provide alternatives to other congested corridors that run through major metropolitan areas.
help to increase trade between the U.S., Mexico and Canada, contributing to a rise in regional mobility and economic status for all three nations.

A recent study prepared by Cambridge Systematics for TxDOT concluded that enhancements to rail, electric transmission lines and highways would improve mobility, safety and economic opportunity along the Ports-to-Plains Corridor.

La Entrada al Pacifico Corridor

The purpose of the La Entrada al Pacifico Corridor is to increase the efficiency of transportation of goods and people from Pacific Coast ports in Mexico northeast to Midland-Odessa, Texas. Mexican ports, such as the Port of Topolobampo, are potentially viable alternatives to the congested ports of Los Angeles and Long Beach. Additionally, the underutilized border crossing at Presidio, Texas is an opportunity to divert traffic from the already overburdened crossing at El Paso.

Currently, the corridor is undergoing a feasibility study, which will:
determine the feasibility of a four-lane divided facility within the designated national corridor, as well as any other corridors identified through the public involvement process.
identify and prioritize potential roadway improvement alternatives along the nationally designated corridor, if a four-lane divided facility is not feasible.
evaluate the economic impacts of future connections and improvements to the infrastructure in Mexico.
identify financial and institutional issues related to the development and construction of the corridor.
provide public involvement through an outreach program and public meetings.

A highway is being built. Your point?

My point..people were repeatly lied to by government. No superhighway, no NAFTA highway, no "whatever you what to call it highway". It just is not Texas..it will involve more states
There is only one reason for this highway..moving goods ..at the American taxpayers expense..across the nation from Mexico to someday Canada..moving goods from other places like China.

As far as a movement for a North American Union (Who knows, I keep an open-mind)
Here is plenty of writings from the CFR (Council of Foreign Relations..which most of the Presidential candidates are members of)

I will agree that we have been lied to. Taxpayers will pay for the construction and maintenance of the highway. They will not pay to move goods. All the articles you list refer to trade. And, they come from a think tank. I'm quite sure that most of the goods will be Chinese; it's not like we make anything anymore.

We face some real problems. This isn't one of them.

I heard something about the merging of our 3 nations that was quite interesting. It's definately not something that the US would be interested in, however I think it's something we could be forced into. The two largest oil suppliers for the US are Mexico and Canada. I'm not a conspiracy theorist, however I do think it's something to keep in mind. Mexico would definately be one for it!
