There's this video circulating of people trying to create a "wave" by grabbing on a shaking the ropes

Very dangerous if they happen to hit the resonating frequency of the structure

I had a teacher who used to work testing resonating frequencies on satellites going up on rockets. Didn't want a launch wasted because it busted sensitive communication equipment.

There's been a number of military reports throughout history of a battalion of soldiers marching across a bridge and causing it to buckle like leather. Myth busters did a great episode on it as well albeit on a much smaller scale

Again, this was debunked, that was a video from 2018. If you're suggesting this 2018 "wave" collapsed the bridge in 2022 when it was supposedly repaired a few months ago, then I also have a large white building in Agra that you might want to buy.

Huh, will be interested to hear new information as/if it comes out. I just want to know to what extreme the bridge was pushed to cause the failure, or which extremes I guess. Rarely is it usually one singular issue but a series of failures on stuff. Overloading a bridge with people (can you do that? Vehicles are heavy, but are people more dense when shoved together?) then having them undulate the bridge would cause some serious stresses I'd imagine. Pair that with quick/shoddy construction, I could easily see that happening.
