If you read the article, it says among the novel features of the bridge is seismically isolated. Supported solely by cables, the deck makes no direct with pylons or abutments. In other words the cables are holding the deck. Can anyone explain the design or fundamental concept for the cables holding the deck? I would appreciate your response at your earliest convenience.
Thanks.

if the deck is isolated from the pylons, being supported by cables attched to the pylons, then the enforced displacement effects will be mitigated (by the elastic strain energy of the cables).
RE: Rion Bridge (Cable Stayed Bridge) in Greece
The connection detail at the abutments is rather complex, given the magnitude of the expected movements, so there is a rotation frame and more dampers.
That is not the only seismic protection feature on the bridge, but it one of the more obvious

Otherwise you would just get a pendulum effect.

Hence the lateral dampers
