suspensioonidena
Suspensioonidena, also known as suspension bridges, are a type of bridge in which the deck is hung below suspension cables on vertical suspenders. This design allows for the construction of long spans without the need for intermediate supports, making it ideal for crossing wide bodies of water or deep valleys. The suspension cables are anchored at both ends of the bridge and are typically made of high-strength steel wires. The suspenders, which are also made of steel, are attached to the cables and the deck, creating a flexible system that can withstand the forces of wind, traffic, and other environmental factors. The deck of a suspension bridge is usually made of steel or concrete and is designed to distribute the weight of the vehicles and pedestrians evenly across the suspenders. One of the most famous suspension bridges is the Golden Gate Bridge in San Francisco, California, which was completed in 1937 and spans 1.7 miles (2.7 kilometers) across the Golden Gate Strait. Other notable suspension bridges include the Brooklyn Bridge in New York City, the Forth Bridge in Scotland, and the Akashi Kaikyō Bridge in Japan, which is the longest suspension bridge in the world.
