As part of its mill complex, Indiana Steel (the subsidiary of U. S. Steel charged with building and operating the plant) constructed its own harbor by removing sand and digging a 23-foot deep channel, with two piers extending more than two thousand feet into Lake Michigan. The harbor provided safe anchorage for large Great Lakes freight ships, including incoming traffic carrying ore from the Mesabi range in Minnesota and outgoing shipments of steel.
