How does it do this? And does anyone know what the signs say?

It's structural frequancy oscillations, usually caused by a wind causing a pendulem affect on the bridge that just get's wrose and worse.

It's happened in America too on a number of bridges.

It ain't fake. Just some bad engineering.

Known as the galloping gurdy, that bridge is now the largest underwater concrete structure on the planet cause they never bothered trying to retrieve any of the fallen materials, it's still laying in the bottom of the sound.

Interestingly, Bridge collapse is a key area of research for those studying Chaos Theory.

Minor permutations in input conditions that produce spectacular output conditions like that
