Beam bridge
A beam bridge is a direct descendant of the log bridge now made from steel "I" beams, box beams (hollow rectangular tubes), reinforced concrete, or post-tensioned concrete (concrete with tubes for cable tendons). It is frequently seen in pedestrian bridges and for highway overpasses and flyovers.
