Many historical examples exist of road and road building. Some of the most famous are the Roman roads and the Incan courier roads. In ancient time, transport by river was far easier and faster than travel by road, especially considering the cost of road construction and the difference in carrying capacity between cart?s and river barges. During the industrial revolution, a development of the road was made: the railroad. Today, roads are almost exclusively built to enable travel by car and other wheeled vehicles, and in most countries road transport is the most utilized way to move objects.
Roads situated in cities are often, but not always, called street?s or alley?s.
