Engraving showing various designs of suspension bridge. Suspension bridges support the load of the bridge deck by means of cables. The cables are often strung through towers and are embedded in masive anchorages at either end of the bridge to provide the necesary tension and stability. Famous examples of suspension bridges include Brunel's Clifton Suspension Bridge over the Avon Gorge, Roebling's Brooklyn Bridge acros the East River in New York and the Golden Gate Bridge at San Francisco, California.
