Beam bridges are often only used for relatively short distances because, unlike truss bridges, they have no built in supports. The only supports are provided by piers. The farther apart its supports, the weaker a beam bridge gets. As a result, beam bridges rarely span more than 250 feet (80 m).

Descendant: Box girder bridge, Plate girder bridge, trestle, truss bridge [citation needed]
