ABSTRACT:
There is disclosed an aerial roadway comprised of prefabricated, cantilevered deck modules; and supporting columns, interlockingly mounted on and monolithically attached to prefabricated, prestressed, post-tensioned spinal beams supported on columns; an elevated roadway comprised of prefabricated cantilevered deck modules monolithically attached to a supporting wall; and a grade-level roadway comprised of deck modules monolithically attached to a foundation located at grade level. The deck modules are provided with integral layers of porous, bituminous paving material which provide a continuous, smooth, water-permeable running surface. Vehicles are directed along the aerial elevated and ground-level roadways by guide wheels depending from the vehicles and impinging on the guide beam fixed to the deck modules. A modification of the cantilevered deck modules provides aerial, elevated and ground-level roadways for transportation systems employing relatively small, light vehicles.
