Bridges are gigantic structures that are usually stationary, so you wouldn’t expect them to move. However, certain bridges are specifically constructed to do so.
All these bridges have been expertly engineered to move to let passing boats go by and ease up naval traffic. For instance, Pont Jacques-Chaban-Delmas’ central part lifts vertically to allow tall ships to pass through. It’s said to be the longest vertical-lift bridge in Europe.
