This bridge, de­si­gned by Tel­ford and com­ple­ted in 1826 could be de­scri­bed as the first major sus­pen­sion bridge. The span of 579 ft was un­he­ard of for any bridge and the chains were made of a new ma­te­rial: wrought iron links, all in­di­vi­dually tested. Span and 100 ft headroom were re­qui­red for ship­ping. Fol­lo­wing this ex­ample, many chain bridges were built.
