Water Transportation

Eddystone Lighthouse is located in the English Channel, 14 miles south of Plymouth, England. The reef upon which it stands was the source of many shipwrecks... and many lighthouses, the first of which was built in 1698. The first three lighthouses were wooden, and suffered the fate of sea storms. John Smeaton  built the fourth lighthouse in 1759 of Cornish granite.   

In the decade following the Civil War, the Mississippi River began to lose its standing as the primary transport artery in the Midwest. Railroads were taking over, and Chicago was rapidly becoming the center of Midwestern commerce. The Eads Bridge was the first major railroad link over the Mississippi, constructed by the city of St. Louis in an attempt to maintain its dominance as a regional commercial hub.

The Dismal Swamp Canal was created as a 22-mile waterway, extending from Deep Creek, Virginia to South Mills, North Carolina. The canal enabled North Carolina producers of building and agricultural products to deliver goods to the Port of Norfolk where they were transferred to ocean-going vessels.   

Before the Davis Island Lock & Dam were built, the flow of the Ohio River slowed to little more than a trickle during dry periods. For several months each year, the unreliable flow stranded Pittsburgh's steamboats, towboats, and barges.    

The Davis Island Lock & Chanoine Dam experimental project was the first lock and dam ever constructed on the Ohio River. Its achievements also included the first rolling lock gates, the largest movable dam built in the 19th century, and the widest chamber in world history.    

The Chesapeake & Delaware Canal is the only canal built in 19th-century America that still operates today as a major shipping route. Connecting the Port of Baltimore and Upper Chesapeake Bay with the mouth of the Delaware River and the Port of Philadelphia, the canal was one of the first civil engineering projects proposed in the New World and one of the most difficult to carry out. Although only 14 miles long, the canal's original cost made it one of the most expensive canals ever built in America.  

The Atlantic Ocean's northward-flowing Gulf Stream meets the southward-flowing Labrador Current at a point marked approximately by North Carolina's Outer Banks. Since the earliest days of United States commerce, shifting tides, inclement weather, treacherous shoals, and a low-lying shoreline there contributed to what soon became known as the Graveyard of the Atlantic. Warning sailors of this danger quickly became a top priority in the integrated system of navigational aids provided by the federal government to promote safe passage along the Atlantic Coast.  

The idea of a canal eliminating the costly and dangerous sea trip around the Massachusetts peninsula of Cape Cod was envisioned as early as 1623 by Pilgrim leader Miles Standish. It was not until financier August Belmont became involved in 1906, however, that sufficient funds for the project could be raised. Belmont had been the primary backer of New York City's first subway, and chose the subway's chief engineer, William Barclay Parsons, as the canal's project director.  

The Old Cape Henry Light house was the first construction project authorized by the First Congress. Constructed by John McComb, Jr. of New York City, this project set the stage for all subsequent public works projects of the Federal Government. In addition, this specific lighthouse was a vital navigation aid to all shipping through the Virginia Capes, thereby enhancing international and coastal trade with the Mid-Atlantic States.  

Most of the locks were 184 feet long and 36 feet wide, able to handle boats up to 160 feet long. The sandstone locks (along with wood miter gates, rock-filled timber-crib dams and bypass canals with guard gates) created a slackwater navigation system stretching over 90 miles.
