SS City of Milwaukee

SS City of Milwaukee is a Great Lakes railroad car ferry that once plied Lake Michigan, often between Muskegon, Michigan and Milwaukee, Wisconsin. She was built in 1931 for the Grand Trunk Milwaukee Car Ferry Company and is the only pre-1940s ship of this type to survive. She now serves as a museum ship, bed and breakfast, and event venue on the waterfront of Manistee Lake in Manistee, Michigan. She was designated a National Historic Landmark in 1990.
