Growing up in Duluth, I often heard that the lift bridge was the only bridge of its type in the world. I later learned that the world is full of lift bridges. Wikipedia lists 137 of them. But that doesn’t mean the claim isn’t true. The lift bridge was once a transporter bridge, a far more rare type of bridge. Aside from various hand-cranked bridges that basically amount to art projects, fewer than two dozen transporter bridges have ever been built anywhere in the world. Only eight of those are still in use. And the world only has one converted transporter bridge in operation: Duluth’s Aerial Lift Bridge. This Duluth Deep Dive takes a closer look at what Duluth’s bridge was like before its conversion by recounting my visit to two of the world’s remaining transporter bridges. One is the closest surviving counterpart to Duluth’s original canal bridge. The other gives a sense what the Duluth bridge might have looked like if the city had modernized the gondola instead of making the conversion to a lift bridge.
