Duluth, Minnesota.
It’s been about 15 years since we last visited the port city of Duluth on Lake Superior. It’s time we went back. With my continuing series on bridges in mind, I decided to reprocess a couple of images from our visit a decade and a half ago.
Hampered by the low pixel count of my Fuji FinePix 3800 I had at the time, I am limited in resolution for these photos, but they didn’t turn out all that bad considering the age of the camera, an early digital model.
But I digress from the subject of the bridge itself. Construction of the bridge started in 1901 and was completed in 1905. The span connects Duluth with a five-mile (8 km) sandbar called Park Point, which is also known as Minnesota Point. Originally a cable car traversed the bridge truss at the top carrying passengers, wagons, and automobiles, but in 1929 it was rebuilt providing a flat deck for vehicles to drive across the bridge. The unique design of the bridge is similar to only one other in the world, located in France.
The opening image features a view of the descending lift as I captured it just after it was raised for the boat we were riding on. When fully extended, the bridge provides a clearance of 180 feet (55 m) to allow taller ships to pass below into the harbor area.
The bridge deck, when lowered provides a roadway some 386 feet (118 m) across. The entire span at the base of the bridge is 502 feet (153 m). According to an article here published by goduluthmn.com, the bridge operates 24 hours a day with skilled operators raising and lowering the bridge an average of 26 times a day in the busy summer season. At one time, pedestrians were allowed to ride on the bridge as it went up and down until a tragic accident that killed a pedestrian in the 1980s.
Over the years, the bridge was reworked five times. In addition to the 1929 rebuild that added the roadway, it was modified for various alterations and repairs in 1986, 1999, 2007, and 2009. The unusual bridge is on the National Historic Registry and it is located near the Lake Superior Marine Museum.

Beautiful photos in the warm light of the setting sun. There is something funny about bridges that are meant to connect and become an obstacle. But the human genius is there to find the solution.
That’s a great way to describe lift and draw bridges!
Lovely image, John. I love the sunset behind it. There’s so much history in these iconic bridges.
There is a similar bridge in western North Dakota, raised and lowered only once during its construction phase to test its operation. The lift was meant to allow steamboat traffic to transit up and down the river. By the time the bridge was completed, there was no more steamboat traffic.
How interesting! It reminds me a bit of the transporter bridge in Middlesbrough here in the UK but that doesn’t have the lower platform, only the top level (https://en.wikipedia.org/wiki/Tees_Transporter_Bridge)
Wow! Interesting implementation. I wonder which is easier, move the bridge up and down, or move the gondola under the bridge.
Good question!
A most unusual bridge indeed, and I suppose the rarity of similar constructions is proof that there were better designs to emulate?
You are probably correct. 🙂
It could actually be quite fun to go up-and-down on it! Pity that it is no longer allowed.
I’ve always wanted to see that bridge in person, JS. Thanks for the photos.
You should plan a trip to Duluth during the fall. The colors in the nearby forests are beautiful.
Many thanks, JS.
Lovely light in these images
It was a beautiful golden hour that was just commencing.
I find it amazing that anyone discovered how to make bridges that stay up, the way I feel about airplanes flying not matter the science behind them. This one doing double-duty is so interesting!
Toonsarah commented here about a bridge that always remains high and a gondola carries cars and people across the river. That, too, is an interesting innovation, Janet. Check out her link to see a photo of it.
That’s a very interesting bridge!
That is truly so, Aletta!
