The San Francisco Bridge and the Millau Viaduct are two marvels but from a different time. Exaggerating a little (perhaps a lot) is like comparing the pyramid of Cheops and the Sistine Chapel.
You made the same error many engineers in the past made with your statement at 6:13: "Bridges over extreme span widths should have a self-stabilizing effect due to their weight". While it is true a more massive bridge is more difficult to set in motion, the problem is once it is set in motion it is also more difficult to stop. Moreover longer spans have more of the bridge exposed to the wind so there will be more wind loading on them. This error by many engineers in the past to rely on a longer and hence more massive bridge to stabilize it led to the collapse of many bridges, including the Tacoma Narrows bridge you referred to later in the video. Wind can cause even a massive bridge to start moving. If the wind is blowing at a particular speed it can start the bridge vibrating at its natural frequency (which is dependent on the shape and structure of the bridge). This leads to a phenomenon called aero-elastic flutter, in which the amplitude of the bridge vibration is continually increased by the wind and can lead to the collapse of the bridge (as happend with the Tacoma Narrows bridge). The proper way to protect bridges from wind induced vibration is not to make the bridge heavier but to use stiffening girders or trusses to make the bridge stiffer. The designer of the Tacoma Narrow bridge assumed substantial stiffening girders weren't needed on the bridge due to its larger weight. He was proven sadly mistaken just four months after the bridge was completed.
In November 2005 I visited the Millau Viaduct; from afar it looked like angels above the gorge ....I have never seen the Golden Gate Bridge , but it is a wonderful bridge.
I go for the Golden Gate Bridge any day considering back then they didn’t have the hightech equipment . And I can imagine how they have to work through the weather . I won’t be surprise if they got the idea of building the viaduct from the golden bridge
As a French engineer, I prefer the Golden Gate Bridge for many personal reasons . But I suggest any American engineer to visit Millau's Bridge for the beautiful landscape and the very different and interesting architecture of this other marvel...
By your logic then you need to concider tower bridge it’s been around longer then the golden gate and the viaduct was designed using specific materials used to counter weather high hurricane winds etc. if you look at the viaduct you will be absolutely amazed on how this colossus was even built it truly is a wonder
The point goes to the Golden Gate Bridge honestly. Even as a 1930s project it would be considered ridiculous to even build these days. So there is one sure thing. No equivalent of those will be achieved ever again in the near future.
I was gonna say the same. Architects have nothing but a mere idea of what goes on engineering and building a bridge. No wonder their comments on what happened to the Tacoma bridge were completely inaccurate.
@@SP-kx4ii Yes, “do that for me engineer, cause I have no idea what I’m talking about.” Maybe that’s why the architect himself commented on the video: “it’s hard to imagine what the engineers went through”
Nothing about death during construction. Anyway these comparisons are nonsense. The technology between 1937 and the end of the XXth century speak for itself. A multispan cable-stayed bridge was not even a thing in the 30's because the requested calculation requires computing so...
Apples and oranges. No comparison. They belong to totally different categories. So, both are fabulous, but not comparible in any manner, except they are bridges
Since I am French I have crossed the Millau viaduct several times, in good weather the view is fantastic and it is sometimes hard not to stop to admire one of the most beautiful and wild landscapes in Europe. On a cloudy day where the fog seems like cotton flakes, you have the impression of flying among the clouds. It's a gripping experience.

This kind of engineering is amazing. Kids, ignore nasa and all the space garbage because that's made up nonsense. Literal pseudoscience.
I feel like I've been living under a rock, I'd never known about the viaduct, it's an amazing bridge, great design.

Your comment is very informative and need more recognition.

Well, it's never too late to get to San Francisco. I've been there twice and absolutely love California.

I love docos. You can relate & learn from them.

It’s funny to me how they put architects to comment on what is completely engineering work.
The Mighty Mac ......crosses the Great lakes!
Keep it up
The golden gate bridge wins hands down in my opinion. First, no computers. Second, no computers. Amazing engineering.
What a view - to a kill
It's not architecture, it's engineering. Stop crediting architect.
It’s the architect design, engineers are the ones making it work, that’s all…it is an architecture marvel as well as great engineering !
@@Bennoit007 some people just comment because they can even though they know nothing just like the one you replied to.
You'll do what your told engineer boy

Frenchman here. I've driven on both bridges, and I aboslutely agree with you. Both are beautiful.
😍
I would be too scared to drive across them especially the viaduct!
I've ridden my bicycle across the Golden Gate Bridge thousands of times over the last few decades.
Stay home then coward

What a bad pronunciation for the name of the french bridge!...
43:18 How GOOD is it built? I hope better than the narrators English.
