====William A. Irvin Ship Museum====
After transporting coal and iron in the Great Lakes for more than 40 years, the {{SS|William A. Irvin}} was docked in Duluth and serves as a preserved example of the shipping history of the Great Lakes. As the [[flagship]] of U.S. Steel's Great Lakes Fleet, she provided what has been called the "comfort and elegance to dignitaries and guests who traveled the Lakes with her" while hauling materials from Two Harbors and Duluth to U.S. Steel's respective mills on Lake Michigan in Ohio and on Lake Erie in Indiana.<ref>{{Cite web |date=April 26, 2019 |title=Vintage Duluth |url=https://dplreference.wordpress.com/2019/04/26/ss-william-a-irvin/ |access-date=January 29, 2022 |website=Duluth Public Library}}</ref>
