ArcelorMittal Indiana Harbor, the largest integrated steel mill in North America, is a behemoth jutting out into Lake Michigan that takes 20 minutes to drive across – longer than it does to cross some entire towns in Northwest Indiana.

It's home to the longest privately owned bridge in the United States and the largest blast furnace. It's so big because it is, in fact, two steel mills now consolidated under the same management — the sprawling steelmaking complex along the Indiana Harbor and Ship Canal spans the former LTV plant to the west and the former Inland Steel mill to the east.
