In 1989, the SS William A. Irvin was officially listed on the U.S. National Register of Historic Places. The museum is located in a picturesque waterfront area, near the famous Aerial Lift Bridge, and is a key feature of the Duluth Entertainment Convention Center.
The ship's main highlight is its technological innovation for the late 1930s. Visitors can see firsthand the unique three-tier bow cabin and the steam turbine system, which was revolutionary for its time and made this ship one of the fastest and most efficient freighters in its fleet.
