Transportation technology
The Industrial Revolution in the 19th century saw a number of inventions fundamentally change transport. With telegraphy, communication became instant and independent of transport. The invention of the steam engine, closely followed by its application in rail transport, made land transport independent of human or animal muscles. Both speed and capacity increased rapidly, allowing specialization through manufacturing being located independent of natural resources. The 19th century also saw the development of the steam ship, that sped up global transport.
Later, tarmac
and concrete became the dominant paving material. In 1903, the first
controllable airplane was invented, and after World War I, it became a fast way
to transport people and express goods over long distances.
Early in U.S. history, most aqueducts, bridges, canals,
railroads, roads, and tunnels were owned by private joint-stock corporations.
Most such transportation infrastructure came under government control in the
late 19th and early 20th centuries, culminating in the nationalization of
inter-city passenger rail service with the creation of Amtrak. Recently,
however, a movement to privatize roads and other infrastructure has gained some
ground and adherents.
