1. History of road By about 30.000 BC convenient routes were being well used by human travelers. The first human pathways would have developed for very specific purposes leading to campsites‚ food‚ water‚ ford across streams‚ passes trough mountains and routes through swamps and past dangerous area. The first record is of a cobblestone paving in Assyria in about 4000 BC. The oldest extant road was constructed trough the mountains of Crete‚ from Knossus to Leben in about 2000 BC. It could have
