The King Iron Bridge & Manufacturing Company of Cleveland, Ohio (later the King Bridge Company) was founded by Zenas King in 1858. Many of the Company’s bridges were used during America’s expansion West in the late 1800’s and early 1900’s and some of these bridges are still standing today. The bridge pictured on this website represent some of the beautiful King iron bridges. We are trying to locate any existing ones in order to preserve these pieces of American history.
