This Multi Span Suspension Bridge is in very deep water in Norway. Deep water means the foundations are very expensive. So it stands on floating pontoons which are tethered to the seabed and held down - so pulled down against buoyancy forces. In order to make it...

This is Seismic Isolation, a means of protecting the structure (like a Bridge) against earthquake. How? It detaches the structure from the ground so that earthquake motions are not directly transmitted.
