A floating suspension bridge is a type of suspension bridge supported by towers built on floating pontoons which are tethered to the seabed. The design is intended to overcome the difficulties of building suspension towers in locations where the water is particularly deep. {{As of|2021}} no such bridges have been built, but a project is underway to build one in Norway, at Bjørnafjord, designed by engineer Ian Firth.{{Cite web|url=https://www.businessinsider.co.za/norway-floating-suspension-bridge-sea-floor-2018-4|title=Norway is getting a floating suspension bridge tethered to the bottom of the sea — and it could change the way we make bridges|website=BusinessInsider}}
