Development of wire cable suspension bridges dates to the temporary simple suspension bridge at Annonay built by Marc Seguin and his brothers in 1822. It spanned only 18 m. [7] However, simple suspension bridge designs were made largely obsolete by the 19th century invention and patent of the suspended deck bridge by James Finley. [9]
Beam bridges are the simplest structural forms for bridge spans supported by an abutment or pier at each end. [1] No moments are transferred throughout the support, hence their structural type is known as simply supported. The simplest beam bridge could be a log (see log bridge), a wood plank, or a stone slab (see clapper bridge) laid

Girder bridges have existed for millennia in a variety of forms depending on resources available. The oldest types of bridges are the beam, arch and swing bridges, and they are still built today. These types of bridges have been built by human beings since ancient times, with the initial design being much simpler than what we utilize today.
Nowadays clapper bridges are only used as footbridges. The Kapellbrücke is a 204-metre-long (669 ft) footbridge crossing the River Reuss in the city of Lucerne in Switzerland. It is the oldest wooden covered bridge in Europe, and one of Switzerland's main tourist attractions. The bridge was originally built c. 1365 [6] as part of Lucerne's ...
Simple suspension bridge: the earliest known type of suspension bridge, and usually a footbridge. The deck is flexible and lies on the main cables, which are anchored to the earth. Underspanned suspension bridge: an early 19th-century descendant of the simple suspension bridge. The deck is raised on posts above the main cables.

Girder bridges and plate girder bridges, usually made from steel, are types of beam bridges. Box girder bridges , made from steel, concrete, or both, are also beam bridges. Beam bridge spans rarely exceed 250 feet (76 m) long, as the flexural stresses increase proportionally to the square of the length (and deflection increases proportionally ...
