LaRouche's idea of the "infrastructure corridor," is currently under discussion, to be implemented, in many nations around the world. It is reminiscent of the idea associated with Abraham Lincoln's concept of the Transcontinental Railway of the mid 19th century. Cities, as industrial, cultural, and educational centers were developed all along the route, as the American continent was developed from the Atlantic to the Pacific. The proper design of the development of any very large land-area must be based on certain geographical principles. In modern history of the past two centuries, the center of these geographical principles is transportation routes, chiefly for water-borne commerce and trunk railways, still the cheapest and most efficient modes for movement of produced goods.
If you want to have an industry, you have to move materials to it and from it. Therefore, you require an efficient transportation system which has a low physical cost of transportation per ton of weight. The most efficient, of course, is rail--rail or magnetic levitation--the lowest in the cost, physical cost per ton mile. Roads are very inefficient, and the only time you use roads, is when it is inefficient to build rail. And you try to use them only for very short distances, because they're very costly, per ton mile, relative to rail. Rail is much cheaper. Water is the cheapest, but that's not land. But, water is slow.
