Midwest Steel & Iron Works

Midwest Steel & Iron Works was a metal fabrication company based in Denver, Colorado. Founded in 1893, the company was known for a time as the Jackson-Richter Iron Works. The company was one of the "oldest and largest metal fabricators" in Denver. The company built both structural and ornamental components for structures throughout Colorado, Wyoming and New Mexico. The company's headquarters on Larimer Street in Denver includes an Art Deco office building and consists of a four-building complex that is itself considered a historic industrial site. The complex served as the company's headquarters from 1923 to 1983.^[1][2]

Among other works, the company manufactured the four Big Thompson River bridges, in Estes Park and Loveland, Colorado, all of which are listed on the National Register of Historic Places.^[3][4]
