The Iron Bridge crosses the River Severn at the Ironbridge Gorge, by the village of Ironbridge, in Shropshire, England. It was the first arch bridge in the world to be made out of cast iron, a material which was previously far too expensive to use for large structures. However, a new blast furnace nearby lowered the cost and so encouraged local engineers and architects to solve a long-standing problem of a crossing over the river. In the early eighteenth century, the only way to cross the Severn Gorge was by ferry. However, the industries that were growing in the area of Coalbrookdale and Broseley needed a more reliable crossing. In 1773, Thomas Farnolls Pritchard[1] wrote to a local ironmaster, John Wilkinson of Broseley, to suggest building a bridge out of cast iron. By 1775, Pritchard had finalised the plans, but he died in December 1777, only a month after work had begun. Abraham Darby III, who was the grandson of the first foundry owner and an ironmaster working at Coalbrookdale in the gorge, was commissioned to cast and build the bridge. The iron for the new bridge was cast at his foundry.
