Suspension bridge

The Chinese were building suspension bridges in the 6th century, although they existed prior to that in the form of drawbridges and footbridges made from vines. Suspension bridges were not built in the Western world until the 19th century. James Finlay (U.S.) built the first suspension bridge in the United States in 1801, at Union Town, Pa., spanning Jacob’s Creek. (Inventions and Discoveries)
