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 when|date=February 2025}}, but a floating suspension bridge has been planned in Norway. This bridge could be more stable horizontally across the bridge 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.{{cite journal | doi=10.3390/jmse8100816 | doi-access=free | title=Static Behaviors of a Long-span Cable-Stayed Bridge with a Floating Tower under Dead Loads | year=2020 | last1=Jang | first1=Minseo | last2=Lee | first2=Yunwoo | last3=Won | first3=Deokhee | last4=Kang | first4=Young-Jong | last5=Kim | first5=Seungjun | journal=Journal of Marine Science and Engineering | volume=8 | issue=10 | page=816 | bibcode=2020JMSE....8..816J }}https://www.researchgate.net/publication/348972910_Dynamic_Behavior_of_a_Long-Span_Cable-Stayed_Bridge_with_Floating_Towers_after_the_Sudden_Failure_of_Tethers_and_Cables_Under_Irregular_Waves
