Arch Bridges

Arch Bridges

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 bridges:

    An arch never sleeps.

    On such a night, when Air has loosed
    Its guardian grasp on blood and brain,
    Old terrors then of god or ghost
    Creep from their caves to life again;
