An elevated roadway for autonomous vehicles may include a pylon extending vertically from a ground anchor and comprising a metal tube defining a central cavity and a concrete column within the central cavity. The elevated roadway further includes a bracket coupled to the pylon and comprising a mounting plate secured to the pylon and a cantilevered road support member extending from the mounting plate. The elevated roadway may further include a cantilevered road section coupled to the pylon via the cantilevered road support member and comprising a joist structure structurally coupled to the cantilevered road support member, a road member above the joist structure and supported by the joist structure, and first and second side barriers along first and second sides of the road member, respectively. The road member may be adapted to receive a four-wheeled roadway vehicle.

A precast concrete beam is provided in construction of a long span bridge structure. The beam is formed of a plurality of aligned modular elements each formed of prestressed UHPC mix as a unitary body. The UHPC mix includes discontinuous fibers distributed randomly throughout a concrete matrix. Each modular element is aligned modular and connected by an epoxy grout to adhering adjacent element joints. Finally, post-tensioning of the entire beam reinforces and affixes the plurality of aligned modular elements into a single long span beam.
