We have bridges that don't do that is the thing. It's just made of metal and reinforced all over.
That bridge was made of metal and reinforced. It was a lesson in why resonance is something that you need to address in design.
Eh, they picked an experimental design that had never been tried before because it was way cheaper than the tried and true safe way. Resonance wasn't the only issue there.
It was nicknamed Galloping Gertie during construction because it moved so much. Apparently everyone though it was structurally sound, which is hard to believe, though may have been the case with vertical vibrations.
The bridge had aeroelastic flutter that was both self exciting and unbounded when winds were above 35mph. This caused torsional vibrations, the bridge twisted instead of the previously seen up and down movement. You can pretty clearly see this in the video posted above.

Vertical movement can be fine; Tom Scott recently did a video on a bridge that moves quite a lot. Enough so that it became a local attraction and engineers were forced to incorporate the movement into repair work!
Positive feedback loops though...that's where things get bad.

Didn't someone tell them to keep their poles out of the right half plane? Positive feedback is not a good thing!

I said the same thing on my last flight to Warsaw.

So like, I referenced this in response to the comment:
Or maybe just stop building giant bridges out of a material that is synonymous with "fragile" and "easily destroyed"
The original Narrows bridge was definitely made out of "non-fragile" materials. It's part of the whole semi-tongue in cheek thing about just staying on the ground. We really don't have to overanalyze it all and make it a thing.

My signal processing professor told the same joke every year:
Why do Polish airliners not have seats on the right side of the plane?
That's the beauty of my pun. I can participate and complain at the same time. Caboose.
Oh speaking of cabooses I once jumped off of a literal caboose that was in motion and very carefully waddled my way back down the tracks for over a 100 yards to a porta potty because it was important that I find a shitter in a way that I'm not sure most people understand.
There were moments I thought I couldn't make it, and there were moments where I thought making it was impossible. Those were the only two mental states possible.
But I did it. I avoided shitting my pants. I managed to spray, and I do mean spray, shit down into the hell that is the receptacle of a porta potty. Imagine the sound of a hose cleaning out a bucket. Then imagine that for an uncomfortable length of time. Coming from a butthole.
That is a thing that happened.
I'm still not sure how the most violent shit that has ever taken place in my life happened when I was like 12 or 13, and for no discernable reason, but it absolutely did.
And the event haunts me still.
Now some may be wondering how this is applicable to the bad news gone right thread.
I refer you to the first four lines.
I did it. I managed to not shit my pants despite the attempted villainy of my bowels.
I submit that is at the very least a potentially catastrophic event going right.

Right, hence I said stay on the ground....
EDIT: Wrong tags.

Basically, in 1940 they didn't design that bridge taking account resonance in the bridge. Now people do.
Also, now it's the worlds largest man made reef - I guess that is a gone right too?

Have you met this thread? It’s pun trains or overanalysis.

To avoid an astable system.
Aaaaand beat’d
And asking Hedgie where the gone right is, let's not forget.
Oh that's fine, sorry, let me be clearer. Let's not overanalyze and make a thing about MY STATEMENTS.

That certainly derailed the conversation.
