Zenas King He started his career of building bridges in 1858 and moved from Cincinnati to Cleveland, Ohio around 1861. He established a bridge building works on Watson Street in Cleveland in 1865. King founded the King Iron Bridge & Manufacturing Company in 1871. As early as 1878 it was manufacturing many types of truss, combination, and wooden bridges and by the 1880s it was the largest highway bridge works in the United States. Production moved from Watson Street to larger facilities on Ruskin Avenue in 1888. The company changed its name to the King Bridge Company after the death of Zenas King. Many of the company's bridges were used during America's westward expansion in the late 19th and early 20th centuries and some of these bridges are still standing today.

The Moseley Wrought Iron Arch Bridge, also known as the Upper Pacific Mills Bridge, is a historic, riveted, wrought iron bowstring arch bridge now located on the campus of Merrimack College in North Andover, Massachusetts. It was added to the National Historic Civil Engineering Landmark list in 1998 and was originally part of the North Canal Historic District on the National Register of Historic Place. It is the oldest iron bridge in Massachusetts, and one of the oldest iron bridges in the United States. It was the first bridge in the United States to use riveted wrought iron plates for the triangular-shaped top chord.

A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements usually forming triangular units. The connected elements may be stressed from tension, compression, or sometimes both in response to dynamic loads. Truss bridges are one of the oldest types of modern bridges. The basic types of truss bridges shown in this article have simple designs which could be easily analyzed by 19th and early 20th-century engineers. A truss bridge is economical to construct because it uses materials efficiently.
