Beam bridges are the simplest structural forms for
simply supported
.
The simplest beam bridge could be a log (see
stone slab (see clapper bridge) laid across a stream. Bridges designed for modern infrastructure will usually be constructed of steel or reinforced concrete, or a combination of both. The concrete elements may be reinforced or prestressed. Such modern bridges include girder, plate girder, and box girder
bridges, all types of beam bridges.
Types of construction could include having many

Because no moments are transferred,
horizontal forces within the superstructure

Beam bridges are not limited to a single
continuous spans
over the piers.
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). This does not mean that beam bridges are not used to cross great distances; it only means that a series of beam bridges must be joined together, creating what is known as a continuous span.
