I remember adding the photos from Google Streetview of the missing X brace to news reports on Facebook after the collapse.

Hello from Pittsburgh! This was my little group of nerds theory as well! Seeing something we've been talking about for weeks rendered out is... kind of chilling? Removing the X beams and letting a bridge with this much traffic ride on temporary cables is an infuriating mistake. We are so lucky no one was seriously hurt. Thank you for this fantastic work. I will be sharing it with other Pittsburghers.

The best version yet! It is so amazing that there were no fatalities.

I really appreciate the work you put into these videos. I find them very educational and helpful for a lay person to understand how every little part of engineering works together. Your videos along with others from engineering community have opened my mind to understand complex concepts that I use daily as a parent with a science minded kid!

I adore the work you put into this videos. So detailed. And wow, the sound design this time. It gave me an eerie feeling at the beginning.

Unbelievable, why no inspections. Thank you.

The most horrible thing in this case is that the local authorities did let people drive over the bridge without proper and solid diagonal support. Second most horrible is that they also let the original support rust away until it broke, before they did something. With this thick material it must have taken years. Where is the supervision and inspection? In my home country this would be impossible. And they do use road salt shitloads every winter here.

Much appreciated. Guessing this recreation was a good amount of work, even for an experienced software user (opines a software tester)

Salt is so devastating to metal. Just look under an old car from Florida vs the north with snow and salt.

see how these people didn't care they knew there was a problem they put up that temporary bracing instead of fixing it the proper way their attitude was it will hold and walked away and never thought about it again until the thing collapsed those who knew about this should be held accountable that temporary brace was shoddy shouldn't have even passed for a temporary brace who's the inspector, that supposably inspected this he should be the first to blame

very clear thank you

Is this an anaglyph stereogram? Unfortunately my depth perception is somewhat impaired or maybe the depth cues in the processed image are a little inconsistent.

add a new support legs behind had been seen more secure

This was a important explanation of what happened to this building that caused death and injury to tenants. Is there any way to educate the public of warning signs that a building is in troubled that might prevent similar events? In reading google apartment reviews some report uneven floors, major problems with a fine dust needing to be vacuumed constantly, heavy water penetration in ceilings and walls, rat activity in walls, etc.carpenter ants, closet doors, windows out of whack and can't close properly, outer bricks powdery, out of alignment. Can any of this data upon confirmation tell us anything that might educate the public, put more eyes on this and prevent future events. Finally because lives were lost this is definitely a form of murder or homicide however there is blood on the hands of many who looked the other way too long.

It was stupid to make this video so dramatic. A "disaster" with no fatalities isn't something people salivate over. A 15-second soundless simulation would have been more than plenty, if even that. It's ridiculous you made this as theatrical as the Champlain Towers South and Chernobyl videos.
