From the ABC story above

Witnesses said the bridge toppled after it was struck by lightning.

Guessing lightning, ungrounded properly, blew the concrete away from the steel. removing either the steel or the concrete results in the failure.

[Fresh Wind]

Every tall building in the world is designed with the possibility of lightning strikes. If designed properly, there is no damage.

Surely the designers of this bridge took that into consideration. It’s not rocket science.

And again, that bridge lasted 50 years or so before it collapsed. I can’t believe this was the first time lightning struck.

I wonder if copper thieves stole the ground cables?
