Atlantic Intracoastal Waterway

The Intracoastal Waterway (ICW) is a inland waterway along the Atlantic and Gulf of Mexico coasts of the United States, running from Massachusetts southward along the Atlantic Seaboard and around the southern tip of Florida, then following the Gulf Coast to Brownsville, Texas. Some sections of the waterway consist of natural inlets, saltwater rivers, bays, and sounds, while others are artificial canals. It provides a navigable route along its length without many of the hazards of travel on the open sea.

Context and early history

Since the coastline represented the national border, and commerce of the time was chiefly by water, the fledgling United States government established a degree of national control over it. Inland transportation to supply the coasting trade at the time was less known and virtually undeveloped, but when new lands and their favorable river systems were added with the Northwest Territory in 1787, the Northwest Ordinance established a radically new and free national policy for their development and transportation use.

Over time, internal improvements of natural coastal and inland waterways would develop into the Great Loop, which allows for waterborne circumnavigation of the eastern continental United States, using minimal ocean travel, with the Intracoastal Waterway providing its eastern end. In 1808, the first federal government report on existing, possible, and likely avenues of transportation improvement was presented; it included much of the distance where the ICW now traverses the Atlantic coast. At the request of the Senate, Treasury Secretary Albert Gallatin presented an overall plan for future transportation developments of national importance and scope. Along with inland east–west improvements, Gallatin's north–south improvements included the following:

While Gallatin discussed the details of engineering, construction, and costs, including the national benefits to accrue from lowered transportation costs between domestic and international markets, his full $20 million, 10-year plan was never approved. That is not to say his plan was never implemented, however, for with experience in the War of 1812 shortly thereafter and the attendant British blockade, the continued need for such facility was soon highlighted. Since Gallatin had based his proposals on the known advantageous natural geographic features of the country, many of his proposals became the locations of navigation improvements that were surveyed, authorized, and constructed starting with the 1824 General Survey Act and the first of many pieces of rivers and harbors legislation, as well by individual state-built improvements.

Since these 1824 acts, the United States Army Corps of Engineers (USACE) has responsibility for navigation waterway improvements and maintenance. All four proposed sections of Gallatin's intracoastal plan were eventually built; the Delaware and Raritan Canal was later abandoned for a better alternative, but the Cape Cod Canal remains in operation, and the Delaware and the Dismal Swamp portions still form part of the larger present-day Intracoastal Waterway.

19th-century growth

In 1826, Congress authorized the first survey for an inland canal between the Atlantic Ocean and Gulf of Mexico. After the Civil War, government funding shifted from waterways to railroads; still, coastal improvements authorized for development included the Houston Ship Channel and the Delaware River in 1872. The following year, the Senate's Select Committee on Transportation Routes to the Seaboard looked at the need for more haulage capacity to move freight to the coasts. But their "Report of Windom Select Committee" their plans and recommendations "received less attention than was anticipated, of course by reason of the rapid growth of interest in railways".

In the River and Harbors Appropriations Acts of 1882 and 1884, Congress signaled its intent to improve waterways to benefit the nation by promoting competition among transportation modes. The 1882 act was the first act of Congress to combine appropriations for development of the nation's waterways with a reaffirmation of the policy of freedom from tolls and other user charges, first stated in 1787; it was passed over President Chester Arthur's veto, who considered it a waste of the federal government's growing budget surplus. In 1887, the Interstate Commerce Act established federal regulation of railroads; Congress continued to promote freedom from tolls or special taxes on waterways. In 1890, Congress passed the Sherman Antitrust Act, the first federal statute to limit cartels and monopolies, but the federal government used it minimally until Theodore Roosevelt's presidency more than 10 years later.

Continued insufficient capacity of railroad transportation became apparent following the harvest of 1906.

20th-century developments

The invention of the diesel engine in 1892 eventually led to the conversion of fuels for transportation from coal and steam to diesel and the internal combustion engine. The Rivers and Harbors Act of 1909 set national policy for an intracoastal waterway from Boston to the Rio Grande, and the Rivers and Harbors Act of 1910 authorized a channel on the Gulf Intracoastal Waterway between the Apalachicola River and St. Andrews Bay, Florida (completed in 1936), as well as a study of the most efficient means to move cargo. Between 1910 and 1914, navigation channels were deepened, and the screw propeller proved efficient for improved steering and flanking qualities. The Panama Canal Act was passed in 1911, which proved key to the revival of waterway transportation in the United States, because the opening of Panama Canal in 1914 allowed coastal shipping to extend to the U.S. West Coast for the first time. The law also prohibited railroads from owning, controlling, or operating a water carrier through the canal and led to succeeding legislation that eliminated monopoly of transportation modes by railroads. The country's World War I experience demonstrated the need for bulk cargo transportation, with Congress establishing the federal barge lines and spurring development of cheaper ways to transport farm commodities, including the first use of standardized freight barges.

In 1924, Congress incorporated the Inland Waterways Corporation, generally regarded as the beginning of modern water carrier operations, and in 1925 it authorized construction of the Louisiana and Texas Intracoastal Waterway, as well as surveys east of New Orleans
