Floating cable-stayed bridge

A floating cable-stayed bridge is a type of cable-stayed bridge where the towers float on tension-leg submerged material, tethered to the seabed for buoyancy. No floating cable-stayed bridge has been made or planned as of 2025^[update], but a floating suspension bridge was planned in Norway before being turned into a floating pontoon bridge and conventional cable-stayed bridge.^[1][2][3] A floating cable-stayed bridge could be more stable horizontally across the bridge deck than floating suspension bridges. The lateral forces from the wind and water pose a problem, which could be solved by placing tethered cables at different angles from the floating platform to the seabed.^[4][5]
