Well, it happened to someone in London in June 2000: check out the "Wobbly Bridge". Fortunately, its lateral movement was cured with hydraulic dampers.
The collapse of the bridge was recorded by a local camera shop owner named Barney Elliott, and in 1998, Elliott's film titled The Tacoma Narrows Bridge Collapse was selected by the U.S. library of congress as being culturally and historically significant.
I don’t know if this is a dumb question or not but how did he record this? They didn’t have home video recorders in the 1940s. Certainly not in color. What is he recording on? I’m curious.
@@dd212NYC my guess would be either an 8mm home movie camera or a 16mm home movie camera. I can’t remember when the 16’s were put into production, but the 8mm cameras have been around since the late 1930’s or so. There’s private 8mm footage taken during the War (WWII) by both the Nazis and the Allied Forces, so the technology is at least as old as when this bridge collapse happened in Tacoma.
@@dd212NYC He was a camera shop owner and had access to equipment that was not commercially popular at the time, including color film. This is 16mm color Kodachrome, he and his co-owner used Bell & Howell Filmos to record, which also saw extensive use during WWII.
What amazes me is the fact that this happened in 1940 and almost the whole thing was caught on camera. Not to mention the quality of the filming is pretty good.
Film is great because it can be unscaled essentially forever. Unlike digital where the resolution you record in is what it is and as of now can’t be upscaled using technology. Crazy that there are multiple angles too
What's amazing is that the bridge started doing this during construction, everyone said, "eh, this is fine" and nicknamed it "Galloping Gertie", and it was used for 5 months until it collapsed.
Thank you for that. I was born in Tacoma 14 years after the collapse, however my mother had told me that she remembered going over the bridge with her father on a weekly basis to meet his friend who lived in Bremerton and that the bridge would rise and sink so much that the car in front of them would appear and disappear between the peaks and troughs. As I understand, this was the way the bridge was designed to function, however on that day there were some unusual crosswinds which caused the bridge to resonate sideways for a substantial period of time which was never expected to happen and caused the collapse.
I remember my grandma telling me the same thing, you'd see oncoming headlights and then you wouldn't. Boggles my mind that it was nothing out of the ordinary to them at the time.
That was not the original design. It was going to be a 4 lane bridge, but they decided to go with 2 lanes & changed the structural properties of the original design.
Brynna Andersen i was wondering why no one made thos joke yet, all i could think about was me driving my car on rainbow road trying to get a perfect jump.
What's really incredible to me is just how much the bridge was able to bend and twist WITHOUT collapsing. Yes, the design flaws that allowed that resonance to occur are what caused the collapse, but the sheer flexibility of it was remarkable. It had been positively gyrating like that for some time before finally failing completely.
There’s something bizarrely beautiful about this. Considering how fluid all the materials are before the collapse, the bridge’s length, the curve of the suspension arcs all make it seem like a living breathing organism or organ.

This perfectly natural for a bridge, we have the best steel here In America, we’ve got five months and I’ll expect another 500 before we have any problem. Galloping Gertie is working In the wind but she’ll hold
I think Tacoma Narrows is credited for having brought the concept of resonance into structural engineering. To me, the interesting part of this is that if the winds had been a little stronger, this bridge would not have collapsed that day. But the wind was blowing at just the right speed to set up a resonant wave in the bridge. It's a bit like swinging your legs back and forth on the swing set as a child - swing them too fast, and you go nowhere.
Wrong. They know about the ressonance problems since Napoleon days. Any troops will NOT march while crossing any bridge, due to exactly the same effect noticed on Tacoma Narrows Bdg. They know the concept since centuries ago, despite of it, mistakes will always happen sometime and somewhere.
Josefina Edlund when concrete is laid in sections, each section suspended by cables, and then covered with asphalt it can appear to be bendable. It's just an illusion. It's really each section doing its own thing.
Life is weird, that professor Farquharson guy was just driving on a bridge one morning then all the sudden gets stuck in this once in a universe situation that will leave him remembered as a selfless hero for hundreds maybe thousands of years after he’s gone.

I live in Belgium, I am 65 years old; I remember seeing this phenomenon on Belgian television in the 60's and I couldn't believe it so much it impressed me, I must have been 6 or 7 years old. It must have been a program on disasters. I did not know until later that it was a serious defect in design. The Golden Gate must have been better designed since it still exists and is well maintained.
The wind was blowing it, e wind kept changing patterns to blow over the top or the bottom, until the bridge snapped. The new bridge has a thicker bace and holes in it so air can pass through. Someone just screwed up badly.
I live about 15 minutes from Tacoma. I've gone over the new bridges many times. Crazy to think this happened in my neck of the woods. The Tacoma History museum has a piece of it that was recoveried on display there. Very good quality footage for being from 84 years ago.
+plazasta It's weird looking at large man made constructions look and behave in ways they weren't intended for. I think watching an abandoned city invokes similar feelings.
+rwoz Well, it wasn't designed to collapse on purpose, but it was designed/intended to flex as most bridges are, and do, in response to many things such as heating and cooling, and wind conditions.
The Golden Gate Bridge only got its first center divider a few years ago. Before it, workers in a truck moved pylons by hand throughout the day to aid traffic flow.
I love how after this they not only rebuilt it but they made another one right next to it. The Tacoma narrows bridge has 2 parts now. One for incoming and one for outgoing traffic.
They made sure to design it correctly this time, with air passages and a more rigid base. It's a miracle this lesson had to be learned with only a dog and a car being lost
The wind gusts were the same frequency as the bridge as said in this video: th-cam.com/video/pFEB0chiuJA/w-d-xo.html at 8:13 he said that the wind gusts and the frequency of the bridge was the exact same and it made that.
@@AmericanIdiot7659 That's a common misconception. The wind was strong, but fairly constant this day .. and that actually was what enabled this design flaw to become fatal. The bridge was well designed for all expected loads, but not very strong against torsion (twisting). So the wind came out of an direction which made it twist a little, the now twisted bridge is even more sensitive to wind, so it twists more, becomes more sensitive to twisting .. until the airflow stalls. Then it swings back to the middle, overshoots a little, and the wind pushes it in the other direction .. it swings back again ... and cycle repeats. Like a reed in a musical instrument, the fairly constant airflow made the bridge oscillate on its natural frequency. It did until the structure failed due to fatigue effects. Wind gusts are no way precise enough to hit the resonant frequency for hours. It was a self-sustaining oscillation, powered by constant wind. Stuff like that was only understood beginning in the 1980s, when we got enough computing power to simulate it .. and it still occasionally leads to problems, since the possible oscillation modes can be very complex and dependent of very minor factors which you left out of the simulation for it to finish in a reasonable amount of time.
The engineer's looked at the bridge afterwards and thought, " If we just made this bridge just a little more flexible, I think we could have pulled it off".
In Grade 10 physics, in 1969, we watched this video. The lesson was the natural resonance of materials. Part of the lesson had to do with WW2, and how soldiers had to break cadence as they marched across bridges. Physics is amazing, and a part of our everydays lives, even though we don't know it!
obc1500 I would have, if I hadn't known that it was due to resonance.When it happened a lot of people probably didn't know what caused it and found it strange.
@@Boz1211111 Everything has a resonance frequency, and when the vibrations caused by the wind match the resonance of the bridge, it became unstable. If you take a finger and rub it around the rim of a wine glass you'll hear it vibrate, and if you do it faster the tone will get higher, slow your finger down and the tone gets lower. Once the vibrations match the resonance of the wine glass, it will shatter even though you're not pushing down hard.
watching this now feels so weird. I remember when I was little (I’m 15 now) i was obsessed with watching this for some reason. I remember the music so clearly
In 2006 I was in the 4th grade and I remember we had a technology teacher that would come into our classroom sometimes and I remember watching this and thinking the music was kind of scary, but I watched it again a few times again within the next few years. I thought the video was cool to watch but the music bothered me all the same. Then I saw this again when my 8th grade teacher showed this to us because of a unit we were starting, and same thing. That creepy music was brought back into my head again. Nowadays, it doesn't weird me out as much but I still get some of the same feeling I used to. I don't know why, but listening to this music while watching this video always made me feel uncomfortable. It's like it makes watching the bridge sway in itself seem eerie.
Guy left the car because car stalled. Dog wouldn't come. Man was old and crawled to land, bruised and bloody. Dog still refused to come as the man was not his owner. Rescue team tried. Dog bit the rescuer. Dog abandoned to die. Poor doggy.
This is the original footage, shot in colour on 16mm Kodachrome stock at 16fps. Any copies you see in black and white were made for distribution as newsreel stock, by MGM, who bought the rights. They made the mistake of think it was shot at 24 fps, so all the black and white version run approx 50% faster than real time. The guy at 2:37 is Professor Frederick Burt Farquharson, an engineer from the University of Washington who had been involved in the design of the bridge, he went to rescue a dog called Tubby, a cocker Spaniel, left in the abandoned car by his owner, Leonard Coatsworth. However, the dog was terrified and bit him, so he left it, and it subsequently Tubby was killed when the bridge platform collapsed into the ravine, the only casualty of the collapse.
Hey guy i am currently studying this phenomenon, i know why it happens, but this looks kinda exagerated, it's hard to believe that it is this way... Is this video real?
luis martin robles 100% real video footage. It was swaying beyond all mechanical limits until it caused the failure. No CGI, nothing is exaggerated at all.
Twenty five years ago, my friend and I were on the Pacific Coast Train from LA to Seattle. The conductor announced we were approaching the Tacoma Narrows Bridge. Most passengers ignored the announcement. We, (both Ph.D. mathematicians) were excited. We knew the history.
+FunOrange Make no mistake. We think we're "soooo smart" and we're past something like this. Sure. Long high bridges are completely insane. They'll keep going down, just like Minne 2007 and those since. Trying to get in nature's face too much. And I'm a techie capitalist.
The footage looks like it's sped up there. (16 fps shown at 24 fps speed instead of at 16 fps speed) Edit: yep, see time-corrected video 13J76PXE6OA at 01:23
80 years ago today; absolutely amazing! I’ll never forget Method of Sections, Method of Joints, and the free body diagram from Statics class! Bend that metal back-and-forth, heating it up significantly due to the internal friction, and the modulus of strength then goes way down. Before long a rigid structure can’t even support its own weight not even factoring in the additional force the winds continue to apply.
The motion of the bridge is that of a driven oscillator. Keep in mind that very few things remain rigid if enough force is applied. ;) But this bridge was designed by Leon Moisseiff to be the most flexible bridge ever built. He didn't realize how that design criteria - being super flexible - would cause this harmonic oscillation problem.
My teacher showed us this video in class 10ish years ago. I am now terrified of crossing bridges and have to mentally prepare myself the day before when I have to cross one while driving
My teacher showed our class that and I was surprised that it was In Tacoma, Washington since i have family there and i crossed there exactly the same image just new, my fear is the bridges doing that tho too 😭
What I find ironic, maybe even haha funny, I've known about this bridge and the collapse for as long as I can remember. (I turned 60 a couple weeks ago). My mom talked about it. I've seen the video several times. Never bothered me crossing a bridge until the bridge in Mt Vernon. I should have been on it that day
Here is an interesting fact. The original Tacoma Narrows Bridge was designed by Leon Moisseiff, the guy who designed the Manhattan Bridge in New York City when it first opened in 1909, and it was his first project long before this. The Manhattan Bridge is the first suspension bridge to travel by cars, with two lanes on each upper level, three lanes on lower and also carries subway trains on the lower level of each span between the three lanes. Manhattan Bridge still stands today, after that, he designed the George Washington Bridge, Triborough (aka Robert Kennedy) Bridge, Bayonne Bridge in New Jersey, Ben Franklin Bridge in Philadelphia, PA, Golden Gate Bridge in San Francisco, CA, and the Bronx Whitestone Bridge right up until this ill-fated bridge opened in 1940 and then collapsed four months later due to high winds.
I live in Astoria, Oregon and we have the big Megler Bridge that crosses the Columbia into Washington. There's also that tall huge bridge that goes into Longview, WA off if highway 30. Do you know if these are related so to speak to the same guy that built the Narrows & Manhatten? Thanx!
+michelle hooper That must be awesome that you live in Astoria, I always wanted to see the house from The Goonies and the film museum in the police building.
I've always been perplexed about that car...Who stops the car and goes "yeah, I can get off this bridge faster on foot" !? just the idea of the car parking confuses me. like why not throw it into reverse and gtfo?
My mom actually saw the bridge fall. My dad said that before the bridge fell when you drove over it in the wind, the car lights in front of you disappeared. He also said there was a bank in Tacoma at the time who had a big Billboard that said "We Are As Safe As the Narrows Bridge!" . . . . After it fell, they took the sign down ;-).
@@InquiringBecause I had the opportunity and cowardly refused! In the years that followed I suffered from three strokes leaving me speechless and motionless in a wheelchair. Through lots of rehabilitation I can pretty good speak more or less fluently again and walk with a stick (like Dr. House, hahaha). That means, I have become kind of "ramshackle man" and thus I am totally unable to move to America! But rather than wallowing in self - pity, I had an encounter with God giving me the absolute encouragement of being in Christ! And that makes me more than thankful and happy!
That car has amazing parking brakes and traction. All that swinging and the car didn't move until the entire bridge collapsed. It is like the car was welded to the road.
Watching this blows my mind. It's not like it took really high winds to do this. It would happen in moderate winds. It's just odd seeing something like that flex in that way, especially when there isn't ridiculously high wind causing it..
Bridges, are made with sections and spaces between called "expansion joints" to allow just so much movement, vibrations, I'm not sure if they were used at the time that one was built or not.
I am not sure but I think it MAY be due to liquifaction. The frequency of the oscillation/waves sort of makes the concrete more like a fluid, similar to a quick sand, like what happens during an earthquake.
Natalie D. Thats true, that Aint funny at *ALL* so if u are on it, u will fall in to the water, drown, and die, Well they said that the will *Never Ever EVER* do this again but for a bridge they have to make it a bit moving, so if its Solide Solide, if a car goes there, the bridge will break and fall and the guy will drown and die
To everyone wondering about the dog: His name was Tubby and he was a three-legged black cocker spaniel. He had wedged himself underneath one of the seats in the car and was too terrified to come out. 3 different guys tried to attempt to save him but couldn't, Tubby even bit one of them. In the end they had to leave him. His body and the car were never recovered. He was the only fatality.
I remember seeing this on an old TV show called When Havoc Struck when I was a kid. Made me sad that a little dog lost his life when the bridge collapsed. Kudos to the guy who tried to get to him.
It always terrified me driving across the 405 bridge through Portland into Vancouver because it's so high up in the air and it "moves". While stuck in traffic, especially when it's foggy out, it's TERRIFYING being stuck on that bridge.
one of my teachers showed me this in 4th grade and it triggered this fear in me i didnt even know i had... like the music and the unnatural movement just completely left me petrified. the shift from color film to black and white just left me feeling uneasy. it still gives me the creeps to this day...
Correct me if I'm wrong, but I was under the impression the resonance was actually caused by air pressure vortices forming around the rigid steel girders underneath the deck (whereas most suspension bridges use trussing to support and stiffen the deck structure).
So for all those who might be wondering what is happening, the bridge is at resonance that is the forced frequency and the natural frequency of the bridge becomes equal and thus the amplitude of the vibration increases making the bridge sway and dance!
Actually incorrect. The cause is aeroelastic flutter. It is a kind of resonance, but the frequency is not a resonant frequency of the bridge itself. The force of the wind blowing over the leading edges of the bridge causes an eddy underneath the span. The eddy results in a pressure drop causing lift on the bridge. As the bridge tilts due to the lift force the eddy intensifies causing further lift, until the eddy breaks up and the leading edge of the bridge moves back down. Because the leading edge has momentum it doesn't stop when it gets to it's starting position and moves past it's rest position and tips the other way. The eddy is now created on the top face of the bridge pushing the leading edge down. This cycle is repeated. Look at the video and you will see the bridge deck twisting. Before failure a suspension cable snaps, temporarily purring the bridge in a different mode of vibration, which led to it's destruction.
It’s like a rope bridge. What must it have been like to try and drive on it! This is mind bafflingly scary. A lot of trial and error in engineering went into the bridges we have now.
Sea life? nah. The puget sound is freshwater, whereas seas are salt water. Still diverse though! Over 3 thousand species! Edit: "Sea" the reply below. Their correction is pretty "sound."
What caused the resonance effect was the design of the solid gerters on the sides of the roadway bed, it gave the wind to much surface area to exert it's forces upon the bridge. The fix was to use open gerters to allow the wind to pass through the bridge instead of around it.
I'm no expert, but I don't think bridges are supposed to do that.

Awww, my dog was named Tubby too. RIP Tubbys.
fiquei muito triste agora eu realmente esperava que ele tivesse sobrevivido... que ele descanse em paz
Thank you so much for this information, I was so concerned for the dog and those who tried to save him. They are true heroes who tried their best to catch the damn dog.
I guess the dog regretted to have done so a "bit" later ...
😞
what caused the bridge to make the music?
Does anyone know the name of the music?
Petar Stamenkovic its generic bullshit by really untalented keyboard player
"Water under Troubled Bridge" ? ;-)
Petar Stamenkovic I wish I knew its awsome

Thank you! Great music!
It looks so creepy when it sways
The bad quality, the black and white, the music, windy... yeah creepy...
It looks like someone is gonna kill someone
@@trishthefish1536 it looks like i want to get on the bridge.
@@Reckless_Metal it's in color
It’s just eerie
I live in Belgium, I am 65 years old; I remember seeing this phenomenon on Belgian television in the 60's and I couldn't believe it so much it impressed me, I must have been 6 or 7 years old. It must have been a program on disasters. I did not know until later that it was a serious defect in design. The Golden Gate must have been better designed since it still exists and is well maintained.
There is a video of the bridges built to replace Galloping Gertie. They are definitely more rigid..
The wind was blowing it, e wind kept changing patterns to blow over the top or the bottom, until the bridge snapped. The new bridge has a thicker bace and holes in it so air can pass through. Someone just screwed up badly.
I'd say a lot of bridges have been better designed.
I live about 15 minutes from Tacoma. I've gone over the new bridges many times. Crazy to think this happened in my neck of the woods. The Tacoma History museum has a piece of it that was recoveried on display there. Very good quality footage for being from 84 years ago.
R.I.P. Tubby. You will never be forgotten.
chairmanmeow1973 as if that dog wouldn’t live up to the millennium
chairmanmeow1973 at least they tried to save the poor dog
Correct, his legend lives on to this day :-)
chairmanmeow1973 dern I didn’t know the dog died
Rip Mr dog slash tubby
I don't know why but there is something about that bridge swaying like that that fascinates me, I can't take my eyes off of that image
yhea its weird
+plazasta the music plays a role into that i think
MyOwnSoul looking at other videos of the disaster I totally agree with that, the music plays a major role
+plazasta It's weird looking at large man made constructions look and behave in ways they weren't intended for. I think watching an abandoned city invokes similar feelings.
+rwoz
Well, it wasn't designed to collapse on purpose, but it was designed/intended to flex as most bridges are, and do, in response to many things such as heating and cooling, and wind conditions.
Good thing they painted a solid line down the middle to keep it safe.
*Sun fucking explodes*
You: "Wow those traffic cones really prevent death don't they huh."
@@grapes5672
It is amazing
Stand on that line if you don't want to swing.
@@zak46 the paint is so sturdy it'll be the only thing left across with collapse.
The Golden Gate Bridge only got its first center divider a few years ago. Before it, workers in a truck moved pylons by hand throughout the day to aid traffic flow.
I love how after this they not only rebuilt it but they made another one right next to it. The Tacoma narrows bridge has 2 parts now. One for incoming and one for outgoing traffic.
They made sure to design it correctly this time, with air passages and a more rigid base. It's a miracle this lesson had to be learned with only a dog and a car being lost
the forces acting on that bridge must've been truly immense, i'm amazed it held together for as long as it did (a few hours if i recall)
Open for traffic for 5 months, actually. It started swaying while it was being built.
The wind gusts were the same frequency as the bridge as said in this video: th-cam.com/video/pFEB0chiuJA/w-d-xo.html at 8:13 he said that the wind gusts and the frequency of the bridge was the exact same and it made that.
@@AmericanIdiot7659
That's a common misconception. The wind was strong, but fairly constant this day .. and that actually was what enabled this design flaw to become fatal.
The bridge was well designed for all expected loads, but not very strong against torsion (twisting). So the wind came out of an direction which made it twist a little, the now twisted bridge is even more sensitive to wind, so it twists more, becomes more sensitive to twisting .. until the airflow stalls. Then it swings back to the middle, overshoots a little, and the wind pushes it in the other direction .. it swings back again ... and cycle repeats.
Like a reed in a musical instrument, the fairly constant airflow made the bridge oscillate on its natural frequency. It did until the structure failed due to fatigue effects.
Wind gusts are no way precise enough to hit the resonant frequency for hours. It was a self-sustaining oscillation, powered by constant wind.
Stuff like that was only understood beginning in the 1980s, when we got enough computing power to simulate it .. and it still occasionally leads to problems, since the possible oscillation modes can be very complex and dependent of very minor factors which you left out of the simulation for it to finish in a reasonable amount of time.
Nitro Engine Hoarder - That’s correct. A self-sustaining oscillation under (roughly) constant airflow.
No they were not immense, the bridge was just poorly built to resist torsional loads. The bridge broke at only a load of 42 mph.
The engineer's looked at the bridge afterwards and thought, " If we just made this bridge just a little more flexible, I think we could have pulled it off".
RIP Tubby. That was the professor's little cocker spaniel that refused to come out of the car. The dog was the only casualty.
I wonder what kind of sounds that thing was making. Must have been severely eerie.
Probably really loud banging and metallic squeaking noises.
+Jake Beadle great now im dying to know what it sounded like

ayy lmao
I first saw this video a long time ago when I still was a kid, and I randomly found this again.
In Grade 10 physics, in 1969, we watched this video. The lesson was the natural resonance of materials. Part of the lesson had to do with WW2, and how soldiers had to break cadence as they marched across bridges. Physics is amazing, and a part of our everydays lives, even though we don't know it!
Happened 74 years ago to the day. LOVE this video it just stays with you and I know no one agrees but I think the music fits perectly
I read about it in my Physics book , people must have found it so strange when they saw the bridge move and then collapse like that.
resonance :D
Since you are "people", you tell me. Did you find this so strange?
obc1500 I would have, if I hadn't known that it was due to resonance.When it happened a lot of people probably didn't know what caused it and found it strange.
+obc1500 nothing is strange after u learn quantum mechanics xD
The views...
Literally the Golden Gate in every Hollywood movie
Same guy designed it
I still dont get it how did it move so much when other simar beidges do not
Hell, Magneto rerouted it.
@@Boz1211111 Everything has a resonance frequency, and when the vibrations caused by the wind match the resonance of the bridge, it became unstable. If you take a finger and rub it around the rim of a wine glass you'll hear it vibrate, and if you do it faster the tone will get higher, slow your finger down and the tone gets lower. Once the vibrations match the resonance of the wine glass, it will shatter even though you're not pushing down hard.
watching this now feels so weird. I remember when I was little (I’m 15 now) i was obsessed with watching this for some reason. I remember the music so clearly
5:38 For some strange reason the bridge is closed, lol.
XD lol
Yeah I wonder why
@XxblackgamerxX Gaming r/woosh
Yea IKR!! Stupid morons closed it so I’ll be late for work now! Pfft
@@dancetomlover99abandoned98 No, why?
In 2006 I was in the 4th grade and I remember we had a technology teacher that would come into our classroom sometimes and I remember watching this and thinking the music was kind of scary, but I watched it again a few times again within the next few years. I thought the video was cool to watch but the music bothered me all the same. Then I saw this again when my 8th grade teacher showed this to us because of a unit we were starting, and same thing. That creepy music was brought back into my head again. Nowadays, it doesn't weird me out as much but I still get some of the same feeling I used to. I don't know why, but listening to this music while watching this video always made me feel uncomfortable. It's like it makes watching the bridge sway in itself seem eerie.
I was shown this in my fifth grade “Challenge” class (gifted and talented) and I still come back to it four years later. Extremely fascinating.
Yeah
Guy left the car because car stalled. Dog wouldn't come. Man was old and crawled to land, bruised and bloody. Dog still refused to come as the man was not his owner. Rescue team tried. Dog bit the rescuer. Dog abandoned to die. Poor doggy.
lol
A German Shepherd would listen, and save its' family.
that dog had it comin yikes
He refused to be saved sooo yeah
😭😭
This bridge collapse has always fascinated me. The amount of energy required to bend steel and concrete like it’s nothing more than putty is crazy.
Welcome to the world of aeroelasticity. It is just science.
And that, folks, is why physics is important
AydarBMSTU IKR
AydarBMSTU yep
Did they keep the concrete pylons when rebuilding the bridge?
This had more to do with aerodynamics
AydarBMSTU we watched this video in my hs physics class haha
This is the original footage, shot in colour on 16mm Kodachrome stock at 16fps. Any copies you see in black and white were made for distribution as newsreel stock, by MGM, who bought the rights. They made the mistake of think it was shot at 24 fps, so all the black and white version run approx 50% faster than real time. The guy at 2:37 is Professor Frederick Burt Farquharson, an engineer from the University of Washington who had been involved in the design of the bridge, he went to rescue a dog called Tubby, a cocker Spaniel, left in the abandoned car by his owner, Leonard Coatsworth. However, the dog was terrified and bit him, so he left it, and it subsequently Tubby was killed when the bridge platform collapsed into the ravine, the only casualty of the collapse.
Why are people saying it's fake or have something to do with a conspiracy? It's got something to do with the frequency, learn science.
Nikola Tesla designed a device that would exploit mechanical resonance.
Hey guy i am currently studying this phenomenon, i know why it happens, but this looks kinda exagerated, it's hard to believe that it is this way... Is this video real?
luis martin robles 100% real video footage. It was swaying beyond all mechanical limits until it caused the failure. No CGI, nothing is exaggerated at all.
Wow just amazing...
Ahem! The resonance!
Twenty five years ago, my friend and I were on the Pacific Coast Train from LA to Seattle. The conductor announced we were approaching the Tacoma Narrows Bridge. Most passengers ignored the announcement. We, (both Ph.D. mathematicians) were excited. We knew the history.
That underside view from Amtrak on the Coast Starlight is Amazing.
These old clips always freaks me out
For some reason, The Music makes the video pretty eerie. As the bridge falls.
we've come a long way since building bridges out of spaghetti

That can be argued, but this is not just concrete.

+FunOrange Make no mistake. We think we're "soooo smart" and we're past something like this. Sure. Long high bridges are completely insane. They'll keep going down, just like Minne 2007 and those since. Trying to get in nature's face too much. And I'm a techie capitalist.

The footage looks like it's sped up there. (16 fps shown at 24 fps speed instead of at 16 fps speed)
Edit: yep, see time-corrected video 13J76PXE6OA at 01:23
Yes, read the Wikipedia article about it. It discusses that.
80 years ago today; absolutely amazing! I’ll never forget Method of Sections, Method of Joints, and the free body diagram from Statics class! Bend that metal back-and-forth, heating it up significantly due to the internal friction, and the modulus of strength then goes way down. Before long a rigid structure can’t even support its own weight not even factoring in the additional force the winds continue to apply.
It's called the Magic of Harmonic Motion. On a weak link.
The motion of the bridge is that of a driven oscillator. Keep in mind that very few things remain rigid if enough force is applied. ;) But this bridge was designed by Leon Moisseiff to be the most flexible bridge ever built. He didn't realize how that design criteria - being super flexible - would cause this harmonic oscillation problem.
i didnt even know it was possible for a bridge to do that.
Neither did the guys who designed it. That was the problem. Now we all know.
+Quoc Le the wind speed was at the same frequency as the bridge natural frequency and the wind couldn't pass thru the bridge causing it to sway
+IRONMANAustralia there is a word for this it was mentioned in skywalk documentary
+Tony Micel Resonance.
+Quoc Le It’s not possible, thats why the bridge collapsed.
Why did someone leave their car on the bridge? Why did they leave their dog in the car if they got out? Poor doggies must have been terrified.
He attempted to recover it as well as a rescue team. The dog was terrified and bit the rescue team
the car broke down probeply

@@Starkesea there was no rescue team!
He left his dog there sadly
Who knew that concrete was that flexible?
Civil engineers.
Not the ones that built that bridge
You clearly have no idea what you're talking about.
Juan Cardenas who are you talking to?
it's not, the concrete already ripped apart everywhere. it was only held together by the steel within the concrete.
My teacher showed us this video in class 10ish years ago. I am now terrified of crossing bridges and have to mentally prepare myself the day before when I have to cross one while driving
My teacher showed our class that and I was surprised that it was In Tacoma, Washington since i have family there and i crossed there exactly the same image just new, my fear is the bridges doing that tho too 😭
What I find ironic, maybe even haha funny, I've known about this bridge and the collapse for as long as I can remember. (I turned 60 a couple weeks ago). My mom talked about it. I've seen the video several times. Never bothered me crossing a bridge until the bridge in Mt Vernon. I should have been on it that day
Here is an interesting fact. The original Tacoma Narrows Bridge was designed by Leon Moisseiff, the guy who designed the Manhattan Bridge in New York City when it first opened in 1909, and it was his first project long before this. The Manhattan Bridge is the first suspension bridge to travel by cars, with two lanes on each upper level, three lanes on lower and also carries subway trains on the lower level of each span between the three lanes. Manhattan Bridge still stands today, after that, he designed the George Washington Bridge, Triborough (aka Robert Kennedy) Bridge, Bayonne Bridge in New Jersey, Ben Franklin Bridge in Philadelphia, PA, Golden Gate Bridge in San Francisco, CA, and the Bronx Whitestone Bridge right up until this ill-fated bridge opened in 1940 and then collapsed four months later due to high winds.
I live in Astoria, Oregon and we have the big Megler Bridge that crosses the Columbia into Washington. There's also that tall huge bridge that goes into Longview, WA off if highway 30. Do you know if these are related so to speak to the same guy that built the Narrows & Manhatten? Thanx!
+michelle hooper That must be awesome that you live in Astoria, I always wanted to see the house from The Goonies and the film museum in the police building.
It's totally worth it. Astoria is an amazing place. Visit the OFM and see what other movies have been filmed there. Then climb the Column.
Fucking Professor Farquharson strolling down the bridge with a pipe in hand. That's class.
epic..........lol great comment
I've always been perplexed about that car...Who stops the car and goes "yeah, I can get off this bridge faster on foot" !? just the idea of the car parking confuses me. like why not throw it into reverse and gtfo?
+stonervivi Car stalled and wouldn't start.
The bridge is wiggling side to side the car could get thrown off.
It would have been a nightmare to drive that heavy car swinging side to side.
Why didn't he pick up his fucking dog though? What kind of dumb fuck stalls his car on a swaying bridge then leaves his pet in it???
Devonian It said (on the wiki) that Tubby was so scared that he refused to move, biting anyone who tried to get him out :(
My mom actually saw the bridge fall. My dad said that before the bridge fell when you drove over it in the wind, the car lights in front of you disappeared.
He also said there was a bank in Tacoma at the time who had a big Billboard that said "We Are As Safe As the Narrows Bridge!" . . . .
After it fell, they took the sign down ;-).
What a cute story, that you made up.
Oops. We forgot about wind shear and oscillation!
😂😂ikr?
"what?"

Dont worry about that, trust me Im an engineer
Wind "shear".
It is shear forcé, not wind shear XD

I can't see anything tho
Fuck that dog
Shut up dude if your a dog hater keep that in your head 98% of people like dogs than cats
I'm a dog lover and a cat lover
That car has amazing parking brakes and traction. All that swinging and the car didn't move until the entire bridge collapsed. It is like the car was welded to the road.
An ironic example of good vs bad engineering lmfao
Why am I watching this on a bridge
what the hell i forgot i commented on this lol
Watching this blows my mind. It's not like it took really high winds to do this. It would happen in moderate winds. It's just odd seeing something like that flex in that way, especially when there isn't ridiculously high wind causing it..
I can't tell if that first bit was a pun or not but I'm digging it.
It was noise I believe which caused it to collapse.
Why is concrete flexible all of a sudden?
Due to steel
It is because of the resonance
Its because a big storm that happened
Bridges, are made with sections and spaces between called "expansion joints" to allow just so much movement, vibrations, I'm not sure if they were used at the time that one was built or not.
I am not sure but I think it MAY be due to liquifaction. The frequency of the oscillation/waves sort of makes the concrete more like a fluid, similar to a quick sand, like what happens during an earthquake.
In 1965 when I was 5 or 6 I saw this footage on a loop at a pizza parlor. I’ve never been the same since.
build a bridge, they said, i'll be fun, they said.
ikr
Natalie D. I don't think anyone think its funny
Ok thank you
Natalie D. Thats true, that Aint funny at *ALL* so if u are on it, u will fall in to the water, drown, and die, Well they said that the will *Never Ever EVER* do this again but for a bridge they have to make it a bit moving, so if its Solide Solide, if a car goes there, the bridge will break and fall and the guy will drown and die
Euan Gethin lol its a horrible way to die if you don't die from impact you'll die from drowning XD
2:30 He's walking rather calmly under the circumstances.
To everyone wondering about the dog: His name was Tubby and he was a three-legged black cocker spaniel. He had wedged himself underneath one of the seats in the car and was too terrified to come out. 3 different guys tried to attempt to save him but couldn't, Tubby even bit one of them. In the end they had to leave him. His body and the car were never recovered. He was the only fatality.
This is so oddly disturbing. The way that shit moves still gives me chills after all these years.
I remember seeing this on an old TV show called When Havoc Struck when I was a kid. Made me sad that a little dog lost his life when the bridge collapsed. Kudos to the guy who tried to get to him.
I live right by the Narrows (where Gertie was), and it's amazing to see how much more has been built around here now... It used to look pretty there.
I remember learning about this bridge at school. Our teacher said thrill seekers used to drive onto it because it was like riding a roller coaster.

It always terrified me driving across the 405 bridge through Portland into Vancouver because it's so high up in the air and it "moves". While stuck in traffic, especially when it's foggy out, it's TERRIFYING being stuck on that bridge.
yeah your talking about the fremont bridge? yeah I dont like that one or the Marquam bridge.
I couldn't agree more!
Tacoma narrows bridge: I will be the best bridge in the world!
Weather: hold my beer
Lol!
So it was the weather who was intoxicating the bridge by incitement?
This is not a hold my beer…okay whatever
It's amazing the beating this bridge took before collapse. Engineering was flawed, but workmanship was commendable.
The age of the video, the music and how cursed the situation looks scares me.
The collapse was not just a tragedy, but also an improvement in bridge engineering design. They learned it firsthand.
one of my teachers showed me this in 4th grade and it triggered this fear in me i didnt even know i had... like the music and the unnatural movement just completely left me petrified. the shift from color film to black and white just left me feeling uneasy. it still gives me the creeps to this day...
Correct me if I'm wrong, but I was under the impression the resonance was actually caused by air pressure vortices forming around the rigid steel girders underneath the deck (whereas most suspension bridges use trussing to support and stiffen the deck structure).
I like your words funny man
You are correct
That music alone is enough to collapse any bridge that was ever built..
TH-cam recommended me a video from USNA about chaos theory and the man mentioned this bridge. Here I am at 42 yr old learning about wobbly things.
So for all those who might be wondering what is happening, the bridge is at resonance that is the forced frequency and the natural frequency of the bridge becomes equal and thus the amplitude of the vibration increases making the bridge sway and dance!
Actually incorrect. The cause is aeroelastic flutter. It is a kind of resonance, but the frequency is not a resonant frequency of the bridge itself. The force of the wind blowing over the leading edges of the bridge causes an eddy underneath the span. The eddy results in a pressure drop causing lift on the bridge. As the bridge tilts due to the lift force the eddy intensifies causing further lift, until the eddy breaks up and the leading edge of the bridge moves back down. Because the leading edge has momentum it doesn't stop when it gets to it's starting position and moves past it's rest position and tips the other way. The eddy is now created on the top face of the bridge pushing the leading edge down. This cycle is repeated. Look at the video and you will see the bridge deck twisting.
Before failure a suspension cable snaps, temporarily purring the bridge in a different mode of vibration, which led to it's destruction.
It’s like a rope bridge. What must it have been like to try and drive on it! This is mind bafflingly scary. A lot of trial and error in engineering went into the bridges we have now.
I watched it in my class, and I had the feeling that this video is so eerie.
It survived way longer than I could imagine..

@@grapes5672 The Puget sound is part of the Pacific, it’s salt water.
What caused the resonance effect was the design of the solid gerters on the sides of the roadway bed, it gave the wind to much surface area to exert it's forces upon the bridge. The fix was to use open gerters to allow the wind to pass through the bridge instead of around it.
Yes - Aeroelastic flutter.
2:45 The closeup view makes this bridge swarving even more scarier.😲😳
