Bridge damage cause rumour

As there has been no official explanation to the cause of the bridge damage I thought I’d share what I heard through the grapevine.

This isn’t proven to be true - just what I heard.

Apparently the construction company removed what they thought was scaffolding but it turned out to be integral to the structure of the beam.

At one point later it made a huge noise and they thought it was going to collapse.

I was wondering what other people have heard? I think it is insane how there hasn’t been anything released about the cause of the damage.
