 The first forms of road transport involved animals, such as horses (domesticated in the 4th or the 3rd millennium BCE), oxen (from about 8000 BCE)
or humans carrying goods over dirt tracks that often followed game trails.Many early civilizations, including those in Mesopotamia and the Indus Valley, constructed paved roads.In classical antiquity, the Persian and Roman empires built stone-paved roads to allow armies to travel quickly.
