Aerial Lift Bridge and more
A major landmark in Duluth, the Aerial Lift Bridge was built in 1905 to carry passengers and vehicles in a gondola across a canal to Park Point. The bridge was upgraded in 1929-30 to its current design, which replaced the gondola with horizontal span that lifts to let a sailboat, tug or massive freighter pass underneath. The bridge takes about three minutes to rise, an event that occurs 25-30 times daily.
Get an up-close view of the bridge at the free Lake Superior Maritime Visitors Center, which offers a look at the lakes' shipping heritage, a map of shipwrecks and a schedule of the boats coming in.
