A transit system is provided for application within existing routes of travel infrastructures, travelling along the median strip and utilizing the air space over the median strip and above limited height roadway traffic and beneath overpasses and height limiting infrastructures. The transit vehicles are supported on or side mounted from trucks operating on an elevated structural beam trackway with a lower upwardly facing support surface, an upper downwardly facing support surface, and (on certain vehicles) an upper medially facing support surface. Variations of the structural beam mount under overpasses or along the ground surface, and are used in switching means for secondary trackways. The transit system's vertical dimension is reduced by the interrelationship of the trucks and structural beam trackway with the transit vehicles, and by placing the vehicle to the side of the structural beam and side supporting the vehicle from the trucks. When the vertical air space for operation is limited, the transit system's vertical dimension is further reduced by a transit vehicle configuration placing passengers in a seated position with head room equivalent to that of an automobile, while traveling and having access side walls and contiguous roof panels acting as a door system, opening in an upward arc for full standing head room for loading and unloading. The stations for the transit system are built along the route of the transit system, over the expressways, again utilizing the land and the airspace of existing expressway infrastructures.
