This view from the entry of the Ship Canal shows the south pier, including both the outer and inner South Breakwater Lights. The lift span of the Aerial Bridge is up, giving a view into the harbor. The "Eiffel Tower" structure near the end of the South Pier of the Duluth Ship Canal held the antenna for the Radio Direction Finder signal which used to be broadcast from there. The tower was left standing after the RDF equipment was removed. When the Ship Canal piers were renovated in 1985-1986, the tower was removed.
