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:
“Men seem anxious to accomplish an orderly retreat through the centuries, earnestly rebuilding the works behind them, as they are battered down by the encroachments of time; but while they loiter, they and their works both fall prey to the arch enemy.”
—Henry David Thoreau (1817–1862)
“... this single span,
Reaching for the world, as our lives do,
As all lives do, reaching that we may give
The best of what we are and hold as true:
Always it is by bridges that we live.”
