When first proposed in 1819, the Hoosac Tunnel seemed so logical. It would provide an efficient and direct route for the Boston and Albany Railroad, whose pathway meandered 20 miles along precipitous grades. Early proponents, however, could not have imagined that blasting a 4.75 mile tunnel through the Hoosac Mountain would require over 20 years of labor. The project took so long to complete that it was commonly referred to as "The Great Bore."

The Granite Railway Company of Quincy was the first commercial railway in the United States. Incorporated in 1826 and designed by Gridley Bryant, the railway relied on horses, rather than steam locomotives, to draw the cars along the tracks. Its primary purpose was to transport granite from Quincy to build the Bunker Hill Monument.

It took 22 years to complete the 35-mile waterway, as funding problems caused the work to shut down from 1777 to 1785.
The notion of creating a canal that crossed Scotland was conceived in the 17th century during the reign of Charles II, but would not be realized for nearly 100 years. The Forth and Clyde Canal, known as The Great Canal in its early years, was the first major transportation project in Scotland and the world's first man-made, sea-to-sea ship canal.

In the 19th century, New York City was a burgeoning industrial and commercial metropolis - the largest city in the United States and second largest in the world. As the city's population increased, people began to call for construction of an underground railway. Many unusual engineering challenges had to be overcome, not the least of which was construction in a dense urban area. After lengthy legal battles over property rights and the debt limit of the city, ground was broken on March 24, 1900.

"Fink's truss design was one of a number of early patented solutions to [the problem of how] to carry a massive, moving weight (a train) over long spans (to avoid the expense of building piers and obstructing waterways) on easily erected bridges (often in rough terrain) with good long-term economy..."

A tiny village on the Rio Grande River in northern New Mexico became the training center for the first American hydrographers and provided the first stream-gauging operations of the U.S. Geological Survey. To plan any water system, it is necessary to know the amount of water flowing in the stream or river at all times - including low, normal, and flood conditions.

El Camino Real (literally, "the royal road") is the oldest and longest historical trail in the Western Hemisphere. The transportation link has, through the centuries, been called various names, including El Camino Real de Tierra Adentro (literally, "the road to the interior" because the U.S. frontier was seen as the country interior to Mexico), the King's Highway and the Royal Highway. It became a transportation lifeline that helped integrate Spanish and European culture in the Southwestern U.S.

The East Maui Irrigation System is Hawaii's most dramatic water story. It began with the construction of the Old Hamakua Ditch built between 1876 and 1878. This privately financed, constructed and managed irrigation system was one of the largest in the United States. It eventually included 50 miles of tunnels; 24 miles of open ditches, inverted siphons and flumes; incorporates approximately 400 intakes and 8 reservoirs.
