A beam bridge is a direct descendant of the log bridge, now more normally made from shallow steel 'I' beams, box girders, reinforced concrete, or post-tensioned concrete. It is frequently used in pedestrian bridges and for highway overpasses and flyovers. As is its ancestor, this bridge is in structural terms the simplest of the many bridge types.

Like most bridges that are characterized by how they are supported, beam bridges consist of one horizontal beam with 2 supports usually on either end.

Decorative beam bridges, commonly built from cedar, pine, and redwood, can span a koi pond or country creek. These free standing bridges are usually built as functional walkways or just for decoration.
