Intracoastal Waterway

TheIntracoastal Waterway(ICW) is a 3,000-mile (4,800 km)inland waterwayalong the Atlantic andGulf of Mexicocoasts of the United States, running fromMassachusettssouthward along the Atlantic Seaboard and around the southern tip ofFlorida,then following the Gulf Coast toBrownsville,Texas.Some sections of the waterway consist of natural inlets, saltwater rivers, bays, andsounds,while others are artificialcanals.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 fledglingUnited States governmentestablished a degree of national control over it. Inland transportation to supply thecoasting tradeat the time was less known and virtually undeveloped, but when new lands and their favorable river systems were added with theNorthwest Territoryin 1787, the Northwest Ordinance established a radically new and free national policy for their development and transportation use.

Over time,internal improvementsof natural coastal and inland waterways would develop into theGreat Loop,which allows for waterborne circumnavigation of theeastern 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 theSenate,Treasury SecretaryAlbert Gallatinpresented 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:

The map of the United States will show that they possess a tide water inland navigation, secure from storms and enemies, and which, fromMassachusettsto the southern extremity ofGeorgia,is principally, if not solely, interrupted by four necks of land. These are the Isthmus ofBarnstable,that part ofNew Jerseywhich extends from theRaritanto theDelaware,thepeninsulabetween the Delaware and theChesapeake,and that low and marshy tract which divides the Chesapeake fromAlbemarle Sound.... Should this great work, the expense of which, as will hereafter be shown, is estimated at about three millions of dollars, be accomplished, a sea vessel entering the first canal in the harbor ofBostonwould, through the bay ofRhode Island,Long Island Sound,and theharbor of New York,reachBrunswickon theRaritan;thence pass through the second canal toTrentonon the Delaware, down that river toChristianaorNewcastle,and through the third canal toElk Riverand the Chesapeake, whence, sailing down that bay and upElizabeth River,it would, through the fourth canal, enter the Albemarle Sound, and byPamlico,Core,andBoguesounds, reachBeaufortandSwansboroinNorth Carolina.From the last-mentioned place, the inland navigation, through Stumpy and Toomer's sounds, is continued until a diminished draught of water, and by cutting two low and narrow necks, not exceeding three miles together, toCape Fear River,and thence by an open but short and direct run along the coast is reached that chain of islands between which and the main the inland navigation is continued, toSt. Marysalong the coast ofSouth Carolinaand Georgia. It is unnecessary to add any comments on the utility of the work, in peace or war, for the transportation of merchandise or the conveyance of persons.

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 theWar of 1812shortly 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 1824General Survey Actand the first of many pieces ofrivers and harbors legislation,as well by individual state-built improvements.

Since these 1824 acts, theUnited 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; theDelaware and Raritan Canalwas later abandoned for a better alternative, but theCape Cod Canalremains in operation, and the Delaware and theDismal Swampportions 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 theCivil War,government funding shifted from waterways to railroads; still, coastal improvements authorized for development included theHouston Ship Channeland theDelaware Riverin 1872.The following year, the Senate'sSelect Committee on Transportation Routes to the Seaboardlooked at the need for more haulage capacity to move freight to the coasts. But their "Report ofWindomSelect Committee "their plans and recommendations" received less attention than was anticipated, of course by reason of the rapid growth of interest in railways ".

In theRiver and Harbors Appropriations Actsof 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 PresidentChester Arthur's veto, who considered it a waste of the federal government's growing budget surplus.In 1887, theInterstate Commerce Actestablished federal regulation of railroads; Congress continued to promote freedom from tolls or special taxes on waterways.In 1890, Congress passed theSherman Antitrust Act,the first federal statute to limit cartels and monopolies, but the federal government used it minimally untilTheodore 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 thediesel enginein 1892 eventually led to the conversion of fuels for transportation from coal and steam to diesel and theinternal combustion engine.The Rivers and Harbors Act of 1909 set national policy for an intracoastal waterway from Boston to theRio Grande,and the Rivers and Harbors Act of 1910 authorized a 9-by-100-foot (2.7 m × 30.5 m) channel on the Gulf Intracoastal Waterway between theApalachicola RiverandSt. 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.ThePanama Canal Actwas passed in 1911, which proved key to the revival of waterway transportation in the United States, because the opening ofPanama Canalin 1914 allowed coastal shipping to extend to the U.S.West Coastfor 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'sWorld War Iexperience 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 ofNew OrleanstoApalachicola Bay;this was the first legislation to treat the ICW as a continuous whole.The River and Harbor Act of 1927 authorized the portion of the Atlantic Intracoastal Waterway, using the route planned out by the Jacksonville District of the Corps of Engineers.DuringWorld War II,the need for efficient transportation of bulk materials within the continental United States was well demonstrated after German submarines sank numerous merchant ships off the East Coast. By 1942, the 9 ft × 100 ft (2.7 m × 30.5 m) ICW channel was completed between New Orleans andCorpus Christi.

Today, federal law provides for the waterway to be maintained at a minimum depth of 12 feet (3.7 m) for most of its length, but inadequate funding has prevented that.Consequently, for larger ships, shoaling or shallow waters are encountered along several sections of the waterway, with these having 7-foot (2.1 m) or 9-foot (2.7 m) minimum depths from earlier improvements. While no tolls are charged for waterway usage, commercial users have been charged afuel taxsince 1978, which is used to maintain and improve facilities. That year, the Inland Waterways Revenue Act imposed a barge fuel tax; originally set at 4 cents per gallon in 1980,it was gradually raised to 10 cents per gallon by 1986.To hold these funds, the act also created the Inland Waterways Trust Fund under theU.S. Treasury,which are used to cover half the cost of new construction and major rehabilitation of the inland waterways infrastructure(33 U.S.C. ch.32).TheWater Resources Development Act of 1986was a wide-ranging bill regarding all water resources utilization nationally. Concerning transportation on waterways, this law established the Inland Waterways Users Board to make recommendations regarding construction and rehabilitation priorities and spending levels for the inland waterways, and also gradually increased the incremental fuel tax to 20 cents per gallon by 1995.

The Intracoastal Waterway runs for most of the length of theEastern Seaboard.The waterway consists of three non-contiguous segments: fromBrownsville, Texas,east toCarrabelle, Florida;fromTarpon Springs, Florida,south toFort Myers, Florida;and fromKey West,Florida, north toPortsmouth, Virginia(milepost 0.0). The first and second sections are collectively referred to as theGulf Intracoastal Waterway,and the third is referred to as the Atlantic Intracoastal Waterway (AIWW). The first and second sections were intended to be connected via a dredged waterway from Tarpon Springs toSt. Marks, Florida(which is near Carrabelle), and the second and third sections were intended to be connected via theCross Florida Barge Canalacross northern Florida. These projects were never completed because of environmental concerns. Additional canals and bays extend a navigable waterway north of Portsmouth. Its unofficial northern terminus is theManasquan Riverin New Jersey, where it connects with the Atlantic Ocean at theManasquan Inlet.North of that is its official terminus point, theAnnisquam River,a U.S. Army Corps maintained channel 26 miles (42 km) northeast ofBoston,Massachusetts,connectingAnnisquamandGloucester, Massachusetts.

The Intracoastal Waterway sees a large amount of commercial activity: barges haul petroleum, petroleum products, foodstuffs, building materials, and manufactured goods. It is also used extensively by recreational boaters. On the east coast, some of the traffic in fall and spring is bysnowbirdswho regularly move south in winter and north in summer. The waterway is also used when the ocean is too rough for travel. Numerous inlets connect the Atlantic and the Gulf of Mexico with the Intracoastal Waterway. The Intracoastal Waterway connects to severalnavigable riverswhere shipping traffic can travel to inland ports, including theMississippi,Alabama,Savannah,James,Delaware,Hudson,andConnecticutrivers. TheSt. Lawrence SeawayandGreat Lakescan be accessed via connections with theHudson RiverandErie Canal.
