In 1779, using a new man-made material, skilled English workmen built a single-span bridge of cast iron over a steep river gorge about 140 miles northwest of London. The result was a 424-ton bridge that was the worlds first iron bridge. It was a turning point in engineering history; as it changed the course of the Industrial Revolution by introducing iron as a structural material.
