Most great monuments of nineteenth-century American engineering, such as the Brooklyn Bridge, dominate the surrounding landscape. By contrast, the Hoosac Tunnel, dug through a mountain in western Massachusetts, is inconspicuous, as tunnels naturally are. Yet it stands in the front rank of the projects of its age by whatever standards of measurement one chooses. On the one hand, its construction, which began in 1851 and ended in 1875, took almost two hundred lives, damaged many reputations, and nearly claimed the solvency of the commonwealth of Massachusetts.

While the Erie Canal  has become well-known in the annals of American history, the Middlesex Canal, built two decades earlier and a model for canal engineers throughout young America, has only recently become recognized for its important achievements. Extending 27 miles northeast from Boston harbor to the Merrimack River near present-day Lowell, Masachusetts, the Middlesex Canal provided low-cost and efficient freight transport for almost five decades, helping to establish the canal in the U.S. as a viable means of economic development.

Baldwin's dry dock in Virginia has been designated a National Historical Landmark and is still in use at the Norfolk Naval Shipyard. The Charlestown dry dock and original pump house, while no longer used, are on display as part of the Boston National Historical Park. Although the need for dry-docking facilities to speed the cleaning and repair of ships in America's naval fleet was apparent as early as 1789, it was the War of 1812, and the burning of Washington, D.C., that finally convinced Congress of the importance of a coastal defense system based on a strong navy.
