A cable-stayed bridge is a type of bridge that uses cables to support the deck, which is the part of the bridge where vehicles and pedestrians travel. These cables are attached to tall towers, called pylons, which rise above the bridge. The design allows for a strong and stable structure, making it suitable for spanning long distances without needing many supports. One of the main advantages of cable-stayed bridges is their aesthetic appeal. They often have a sleek and modern look, which can enhance the beauty of the surrounding landscape. Famous examples include the Millennium Bridge in London and the Leonard P. Zakim Bunker Hill Memorial Bridge in Boston.
