who built some of the first roads in america
History of road transport The first forms of road transport were horses, oxen carrying goods over tracks that often followed game trails, such as the Natchez Trace.[1] In the Paleolithic Age, humans did not need constructed tracks in open country. The first improved trails would have been at fords, mountain passes and through swamps.[2] The first improvements would have consisted largely of clearing trees and big stones from the path. As commerce increased, the tracks were often flattened or widened to accommodate human and animal traffic. Some of these dirt tracks were developed into fairly extensive networks, allowing communications, trade and governance over wide areas. The Incan Empire in South America and the Iroquois Confederation in North America, neither of which had the wheel, are examples of effective use of such paths.
