An arch bridge is a bridge with abutments at each end shaped as a curved arch. Arch bridges work by transferring the weight of the bridge and its loads partially into a horizontal thrust restrained by the abutments at either side. A viaduct (a long bridge) may be made from a series of arches, although other more economical structures are typically used today.

Famous quotes containing the words arch and/or bridge:
“Concord’s little arch does not span all our fate, nor is what transpires under it law for the universe.”

“Crime seems to change character when it crosses a bridge or a tunnel. In the city, crime is taken as emblematic of class and race. In the suburbs, though, it’s intimate and psychological—resistant to generalization, a mystery of the individual soul.”
