No it doesn't. The "free trade" system does that, and that is precisely why Karl Marx opined that "free trade" could be used to create a global socialist society.
The portion in Texas of the project states its purpose and has nothing to do with CFR or any conspiracy
Trade traffic and the additional traffic resulting from the state’s economic growth of late have combined to put a great deal of stress on the Texas road network. Most notable is the Interstate Highway 35 corridor, which originates at Laredo and has become the primary trade corridor between Mexico and all parts north. Other affected highways in the state include US Highway 281, originating at McAllen; US Highway 77, originating in Harlingen; US Highway 59, originating in Laredo; and US Highway 277, originating in Del Rio. Also heavily affected are the various arterial roads providing connections between the border and Interstate Highway 10 in El Paso. Congress has designated these NAFTA corridors, along with other highways that connect to them, as parts of “High Priority Corridors on the Nation’s Highway System
These corridors will help extend NAFTA trade north and south. By 2010, some 2,000 barriers to the movement of goods, services, and money among the three signatory nations will be eliminated, with Texas retaining unsurpassed links to its hemispheric neighbors.
Immigration laws are a barrier to trade in services, btw.
