Economic developments
In the early nineteenth century, the United States changed rapidly and a distinctive American identity emerged.
As settlers poured westwards, the United States developed a transport infrastructure to cope with the movements of population. In 1806 congress authorized the National Road (also known as the Cumberland Road), America’s first interstate highway. Construction started at Cumberland, Maryland in 1811, and the road reached Vandalia, Illinois, in 1839. The West was becoming increasingly significant.
Since 1817 the Erie Canal had been under construction and was opened in 1825. At 363 miles long and with 83 locks it was the longest canal in the world, and it cost $7 million dollars to build. By linking the Great Lakes with New York City via the Hudson River, it connected the Western interior to the Atlantic.
In 1828 the cornerstone for the Baltimore and Ohio railroad was laid on 4 July 1828. At the end of 1829 it carried passengers on the first completed 13-mile stretch. By 1850 America had nine thousand miles of track.

Agriculture remained central to the American economy: cotton and tobacco in the South, grains and livestock in the North and West. Industry was also growing, as skilled immigrants brought with them their knowledge of British production technologies. In 1822 Boston investors opened the mechanised Lowell cotton mills along the Merrimack River. However the majority of American towns were commercial rather than manufacturing centres, providing goods and services for the surrounding farms. It was only after the Civil War that industrialization seriously took shape.
