Bridges were one of the first structural uses of iron, preceded only by columns (not yet beams) to support the floors of textile mills. Figure 7 Dunlaps Creek Bridge (1839), Brownsville, Pennsylvania (USA), spans 80ft (24m) on five elliptical ribs of cast iron made of nine 14ft (4m) segments flanged at the ends and bolted. The triangular bracing in the spandrels is reminiscent of Telford's iron bridges in Shropshire (UK), and the tubes resemble the eliptical arches of the Pont du Carrousel, built over the Seine in Paris in 1834. Library of Congress The first successful all-iron bridge in the world was designed by Thomas Farnolls Pritchard, an architect who suggested using the material as early as 1773. Built by two ironmasters, Abraham Darby and John Wilkinson, to demonstrate the versatility of cast iron, the bridge spans 100ft (30m) over the River Severn at Coalbrookdale (UK), on five semi-circular ribs of cast iron.
