Topeka Bridge & Iron Co. was a bridge company. Its works include many bridges that are now listed on the U.S. National Register of Historic Places. Its Canyon Diablo Bridge was a concrete Luten arch bridge built in 1914. Its Amelia Park Bridge, for another example, was built in 1914.
A state of Arizona study asserts that "All of the concrete Luten arches identified in Arizona are associated directly-either through engineering or construction-with the [firm], the western representative of Indianapolis-based engineer Daniel B. Luten." For the Inspiration Bridge in Miami, Arizona, the town engineer built the bridge in 1921, and then four others exactly like it, from plans and specifications ordered from the Topeka Bridge & Iron Co. The Topeka Bridge & Iron firm "also sent moulds with which to cast the decorative concrete balusters for the guardrails."
