The King Iron Bridge & Manufacturing Company was an American bridge building company. It was based in Cleveland, Ohio, United States, and was founded by Zenas King in 1858. It was later managed by his sons, James A. King and Harry W. King, and then his grandson, Norman C. King, until the mid-1920s. Many of the bridges built by the company were used during America's expansion west in the late 19th century and early 20th century, and some of these bridges are still standing today.

Remaining examples

Additional bridges designed and/or built by the company (and many likely to be surviving) are:

Through truss railroad bridge over Rock River in Rockford, Illinois.
Abandoned Rock River railroad bridge in Rockford, IL. Now used for a rail-trail.

Hendricks Ford Bridge (1880) Edinburg, Indiana
