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.

“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)
“As night is withdrawn
From these sweet-springing meads and bursting boughs of May,
Dream, while the innumerable choir of day
Welcome the dawn.”
—Robert Bridges (1844–1930)
