In today's highlighted photo one can see a freighter leaving the Duluth harbor, making its way underneath the Aerial Lift Bridge, past Canal Park, and heading out to Lake Superior. The second photo shows the road portion of the bridge back on ground level, allowing connection of an island to the mainland. The Aerial Lift Bridge is a vertical lift bridge which is a major landmark in the port city of Duluth. The bridge was built in 1905 and upgraded in 1929-30 to the current lifting design. The bridge was added to the National Register of Historic Places in May 1973.
