One of the primary ways that the Mississippi River presently serves as an industrial infrastructure is by hosting the Port of South Louisiana.
There are several things that make the Port of South Louisiana unique. First, unlike most ports, which tend to be concentrated, most contiguous, and roughly bounded within a rectangular area — think of southern California’s Terminal Island, the Newark terminal of the Port of New York-New Jersey, or the emerging megaport in Savannah — the Port of South Louisiana is a distributed, linear port, stretching 54 miles along the Mississippi River between New Orleans and Baton Rouge. (It owes some further formal peculiarity — the distinctively long lots, which have a slim piece of river frontage but a deep extension away from the river, perpendicular to the river rather than parallel to one another, to Louisiana’s French history.)

The cement facility, which includes dome storage, is one of the largest in the United States. Cargo is quickly moved to and from landside storage via an extensive covered conveyor system."]

Second, again unlike those ports, the Port of South Louisiana primarily handles bulk goods — raw materials like oil, cement, woodchips, and mineral ores. (South Louisiana is the Western hemisphere’s largest port as measured by tonnage annually handled — some 192,853,000 metric tons in 2009.) This produces an entirely different spatial form. The landscape of the container port is determined by requirements produced by the dimensions of the standard shipping container (the twenty-foot equivalent unit, or TEU) and the Panamax freighter. The bulk port is more idiosyncratic — various unloading mechanisms and devices, such as the jumbles of unloaders, conveyors, and storage facilities seen above, are used to handle the vast area of materials the port loads and unloads — but it does fix on the dimensions of the “standard jumbo hopper barge” and the typical barge flotilla size (above St. Louis, 15; below St. Louis, 40-50).
