Transportation in the United States has evolved over the years from boats and animal-drawn wagons to powered trains, cars and aircraft. Dramatic changes swept the globe between 1800 and 2000, introducing ever-faster means of transportation.
One of the most common methods used to travel long distances in the early years of the United States was to follow the country's long rivers and coastlines. As railroads expanded, they offered a fast and convenient way to move people and cargo over land. In urban centers, bicycles and wagons offered short-distance transport.
The 1900s saw the introduction of electric trams and cars, reducing man's dependence on horses in cities. Airplanes were invented and airlines started offering scheduled services. Moreover, freeways and large roads made it easier for cars to travel long distances.
