The narrator is very understandable. I didn't find a single grammatical error. He is friendly sounding without sounding "preachy." Very good job. Do more. Thanks.

imagine being one of the people that turned around at the beginning of the bridge because it collapsed in front of them. those 15 seconds that you took to find your missing keys could have potentially saved your life. just comes to show how every second in life matters and every tiny little event can add up to your death or to your savior. stay safe everyone.

The i35w bridge wasn't a design flaw, it was a maintenance error. The reason the bridge collapsed was one of the plates connecting the bridge to the trusses was bent and no one reported it until the thing fell

If that first bridge had collapsed even a week earlier than it did, I could have lost my father. He had a business trip in the area and crossed that bridge every day during it while commuting for work. It's honestly terrifying to think about.

I'm glad you included that Italian bridge collapse in '18. That was visually really horrifying as the bridge was so tall and huge. Plus there were so many buildings right up under each end! I wonder how they managed to demolish it without taking out peoples' homes.
I'm just waiting for the other shoe to drop re: the new SF Bay Bridge (Oakland half.) It was made with cheap steel and has major design flaws involving corrosion and bay water seeping in where it shouldn't be. There's been an ominous silence about all that since it first hit the papers.

America's policy on public infrastructure: (example)

01 - Bridge gets build as cheap as possible.
02 - Building companies decreases cost even more by cutting every corner.
03 - Bridge gets inspected due to a deadly bridge collapse for the first time in decades and many potentially fatal structural issues are reported.
04 - Politicians decide it is not the right time to start repairs and can wait till after elections and report gets filed on top of a stack that already contains countless high priority actions.
05 - Elections have taken place but nobody is willing to start about the report and politicians make sure that the report will never see daylight again.
06 - Another bridge collapses and federal government mandates all major road bridges to be inspected and again numerous, potentially fatal flaws are reported.
07 - Step 3, 4 and 5 get repeated and from this point and Inspections are no longer made because none of the local politicians is willing to take his or her responsibility and demand action. And so again, nothing happens and reports are getting filed.
09 - After this the bridge finally collapses under normal load, taking some hundred lives with it.
10 - Federal government now demands that all bridges have to be inspected but this takes years.
11 - In the end countless potentially fatal structural issues are being reported and repair budgets are being made and presented to local politics.
12 - Again, politics find the costs for rebuild too high and again, despite all promises, decisions get delayed till after the next elections and are conveniently being forgotten.
13 - Repeat steps 1 to 12.

Sincerely yours, a foreign observer.

I live and have had to drive the Tacoma Narrows Bridge often. I can attest that you can still feel the bridge move and sway on windy days. It can be a scary bridge to go over during those moments.

Tacoma bridge was an example of undamped oscillations. Something you learn about when studying Differential Equations.

I was on the 35W bridge the day it collapsed. The traffic, as usual was crazy. I feel for every family affected

[adriennegormley]

Ah, you DID include Galloping Gertie (Tacoma Narrows). No top list of collapsing bridges would be complete without her.

In Minnesota we call it the 35W bridge disaster. When they fished the collapsed bridge out of the water they laid it on the flat ground there in an area called Swede Hollow. The pieces sat there for a long time until a couple of years ago when the Minnesota Department of Transportation said they were going to cut up the pieces for scrap. My wife and I went down there to take a look at it before they started cutting. From what I saw it's amazing it stood up as long as it did. The wall sections of the girders were not that thick, in fact, the whole thing looked pretty flimsy. One thing that doesn't get mentioned is the difference between building for today vs. looking into the future to guess at what the bridge will have to carry 50 years down the line. It's so much cheaper to build for today and that's what happened here. They never planned on the tremendous growth in traffic nor did they contemplate that a contractor would dump concentrated piles of building materials on the bridge for use while they were repaving it. I don't think any thought was ever given to determining if the bridge could take additional weight. It was always assumed it would take whatever you put on it.

The Hernando DeSoto bridge in Memphis was recently shut down for three months after inspectors found a crack that went almost all the way through a support beam.

My dad helped rebuild I-35 bridge. He was gone 20 hours everyday for 2 yrs…

[pinkraynedrop]

You SHOULD have included the Westgate bridge in Melbourne, Australia. That killed a lot of workers that were on it at the but it was rebuilt and is still there.

[williamsl]

The fact it took them only a year to construct the new bridge in Italy worries me.

It took workers over a year to repaint the Transporter Bridge here in the UK... to just paint it. Oh there were a few fixes along the way. But it's nowhere near as long or as complicated as designing, approving, beginning construction etc of a new bridge.

Not a chance would I use it or live under it.

I graduated from college in May of 2007, the Bridge fell in August 2007. By then, I had moved to a different state. I got chills considering I drove across that bridge so many times.

[cliftondean]

The Tacoma Narrows bridge (Galloping Gertie) was hardly a "sudden" collapse. Although its lifespan was much shorter than planned, the oscillations were noted early on and engineers calculated to the hour when the bridge would collapse. It was within a few minutes of the predicted demise.

[nateverge]

You could do a whole video on Washington bridges. We've sunk at least two floating bridges, as well as the Tacoma Narrows & other failures.
