Cable-stayed bridge: deck supported by inclined cables anchored to towers (pylons). Cables are in tension; towers in compression; deck in compression (pre-compressed by cable horizontal component). Different from suspension bridge: cables anchored directly to tower, not to a main cable. Advantages: longer spans than girder (200–500 m), less material than suspension, aesthetically appealing. Examples: Bandra-Worli Sea Link (extradosed), Vidyasagar Setu (Kolkata — cable-stayed).
