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:
“Thir dread commander: he above the rest
In shape and gesture proudly eminent
Stood like a Towr; his form had yet not lost
All her Original brightness, nor appeard
Less than Arch Angel ruind, and th excess
Of Glory obscurd: As when the Sun new risn
Looks through the Horizontal misty Air
Shorn of his Beams, or from behind the Moon
In dim Eclips disastrous twilight sheds
On half the Nations, and with fear of change
Perplexes Monarchs.”
—John Milton (16081674)
“to-morrow it seem
Like the empty words of a dream
Remembered on waking.”
—Robert Bridges (18441930)
