A cable-stayed bridge is a type of structure where the bridge deck is supported by cables that are connected to one or more vertical towers, known as pylons. The cables are arranged in a fan-like pattern, distributing the weight of the bridge evenly. This design allows for longer spans compared to traditional beam bridges, making it suitable for crossing wide gaps. The main advantage of cable-stayed bridges is their efficiency in material use and construction time. They require fewer materials than suspension bridges, which rely on cables hung from tall towers. This makes cable-stayed bridges a popular choice for modern infrastructure projects.
