I appreciate that they went above and beyond to create a 3D version of the engineer, just so we can see him proudly cross his arms..

Very realistic animation. Especially the part where one worker ran the cable while 2 others just stared at the water. 😂

Anyone else here after Baltimore's Key Bridge accident and collapse?👀 Great video, by the way. Very insightful!

Designing and rendering a 15 minute animation like this is also quite a feat of engineering, especially one with as much detail as this one. Thank you so much for all the hard work and time putting this together

They made all this in a time when there was no CAD and other simulation softwares. It's truly remarkable.

I'm not even that into civil engineering but this was REALLY fascinating to watch and learn about.

I appreciate how the sharks just calmly watch the divers working to place the bombs, like "Leave em alone, they're doing complicated work here.."

I'm here after the Bridge collapse in Baltimore. Very very tragic 😞

Whoah, Lesics would make anyone fall in love with physics. Brilliant production, perfectly explained. Free content can't get better than this.

I'm very interested in the work of those divers. I just can't wrap my mind around doing construction in those underwater conditions. Amazing!

They started painting it 86 years ago and have never finished because by the time the last part is painted the first part needs paint again. Imagine being a professional painter and spending your entire career painting only one structure.

Shout-out to the construction workers for risking their lives to make this project a reality

14:33 I attended the bridge's 50th anniversary in 1987. When the bridge operators approved the temporary closure to vehicles, they estimated 50,000 would attend. The actual number was estimated at peak, close to 800,000 had come, far more than could even fit on the bridge. You can find photos that show masses of people stretching back on to land, unable to reach the span. I attempted to cross the bridge - end to end. It was so crowded that after two hours, I only made it from the toll booths to mid span. The sag was visible. Could you imagine if the cables snapped, killing several hundred thousand? Even though the bridge held up fine, the bridge operators said they will NOT repeat such an event.

Joseph Strauss was officially the Chief Engineer, based primarily on his long history of building drawbridges throughout the country. But for the GGB, Strauss had absolutely no involvement with its design. The suspension design was proposed by Leon Moisseiff, a Latvian immigrant who had been involved on other large suspension bridges in New York, and it was he who had the idea of an elegant suspension bridge. The real brains behind turning the concept into a well-designed structure, however, belongs entirely to Charles Ellis, a meticulous structural engineer who personally made all the static and dynamic load calculations, including solving some equations with 37 variables…all done without the benefit of computers. Strauss became so irritated with the attention Mr. Ellis was getting from the press and other engineers that Strauss canned him. It wasn’t until the 75th anniversary of the bridge’s completion in 2013 that a plaque was installed on the bridge to honor Charles Ellis as the true designer.

Always fun to see computer animation of the bridge construction. Reminding us that the actual design and work was done in the 30’s

Each procedure is so interesting that I'd love to watch entire videos explaining each step further. It's a marvellous structure!

8:46 Total Jump scare

It's astonishing how everyday things that surround you and that you normally don't think much about have such ingenious stories behind them!

Never cared about this kind of stuff but last year i rode my bicycle from Canada to Mexico and i remember crossing the GGB at around ten miles an hour and actually able to stop to admire it and not be moving with traffic, but it was one if the best parts of my trip. On the north side of the bridge is this cool little park where you can stand at the base of the supports and just really get to admire the whole thing. Super cool video thank you.

this is becoming my favorite channel on yt. thank you guys so much for the work that you do! these videos are incredible and honestly so well-made that it's kinda shocking. please keep making these!

Fun fact. The Golden Gate Bridge undergoes constant maintenance. There is a crew that works from one end of the bridge to the other. They repair and replace rusted out pieces and repaint as they go. This is a never ending loop. When they reach the end the crew goes back to the other side and begins the process all over again.

He was a genius he didn’t have todays technology much respect to the designer and his family the Golden Gate Bridge is a wonder of our world

Subscribed. Im so happy that something inside of me snapped and decided to learn about stuff about the world, from ancient times to modern times, from old civilizations to modern structures also. You go to the points, good animation and visualizations! Thanks a lot for sharing!

This will be the replacement for the Baltimore bridge

Amazing! The wisdom knowledge and skill to get this done at that time (1930s) is beyond me! Thank you Lesics for always making these well animated and explained videos!

This man with his engineer colleagues designed this bridge without advanced CAD and simulation programs and computers. Using just pencils, papers and editing tools like rulers and drawing compasses. Today it is still standing there and get the job done, between those harsh environments.

Great video presentation. They forgot to include the bridge road to be slightly arched, like an old arch bridge design. It may lessen the tension of the cables and reduce damage when the road deck steel expands. When the finger expansion has no more room for expansion, the steel road deck will push horizontally and may damage the two towers. When the road deck is slightly arched, it will just push up to lessen compression. The designers are very smart. It's a combination of an arch bridge and a suspension bridge.

Thank you so much for this animation I was a union ironworker local 86 Seattle Washington I'm 67 Now so seeing all of this just brings back memories I even got to work on the Golden Gate a small retrofit job froze my ass off on on the south end thanks for presentation

9:08 the first bump was awesome!!!

Just started learning framework of bridges in my school, and i was very curious on how bridges are made ever since then. This really helped me understand alot.

I'm so honored to see this engineering introduce in this video. Thank you.

The production of this video is awesome. Thank you for such a great explanation. This video should be on display for visitors of the bridge. I would have definitely appreciated the bridge even more if I’d seen this video.

My Grandfather (1890 - 1964) wrote a book on the engineering of the bridge contemporarily with its costruction. (1935). He was an engineer for the City of San Francisco. BTW. I don’t think they used roller compacted concrete. I inherited a small piece of one strand of the cable and splice from my mother. The Golden Gate Bridge will always be the standard for beautiful infrastructure. His book is still for sale at the gift shop.

So many engineering challenges solved with master level solutions, and on top of that a great animation to explain it all. Excellence!

Man, you are brilliant. One of the best KZfaq channels. Not just my grandson (who loves everything engineering) enjoyed the video, but I also learned a LOT of interesting things.

Additional facts: At the time of the Golden Gate Bridge's construction, no steelworks on the West Coast could produce components large enough to construct the towers, so they were shipped via the recently finished Panama Canal from the East Coast (New York specifically I belive) The Red color originally was to be a temporary coat to protect the bridge while a final color could be chosen (the navy suggested yellow/black stripes for visibility reasons) but it was stuck with as the locals were fond of it The Bridge was constructed with an unprecedented (for the time) emphasis on worker safety, to the point as far as I'm aware there was only one fatal accident during construction.

13:40 The support wire runner-layer is amazing. You can't find people today to do that kind of work.

A very enlightening education! Just incredible how brilliant these engineers are. They are the heroes that make our lives better, not pop stars or movie stars!

Amazing engineering. Thank you for your clever & clear video 🎉

2:16 I love how Joseph is just like a good 300 feet tall. makes sense.

That is why i as civil engineer really fall in love with these kind of mega structures. Only those who worked on structures know how they built it. For normal people it is just bridge to connect with each other but for us it is more than that it is our emotions, our commitment and love to our country.

No way this popped up on my recommendations after the Baltimore bridge incident 💀

I always wondered what was so special about a simple bridge, now I know. Thank you. I love learning random information.

The way he appreciates, credits and mentions the chief engineer, divers and even the cable workers proved the knowledge is nothing without discipline, execution, teaching and spreading them. He deserves an Oscar for such a animation film

They give Strauss far too much credit here (a common mistake)! Strauss did come up with the concept of bridging the golden gate, and was its chief promoter, a herculean task in itself! However, he primarily designed cantilever bridges and did not have the engineering experience to create the suspension bridge that was built. Charles A. Ellis was the primary engineer. Also, they show the traffic flowing in the wrong direction on the bridge. Our steering wheels are on the left in San Francisco!😂 Other than that, a very interesting video!

Another great childrens education vid from Lesics! My 4 yr old loves these!

I grew up in SF and loved seeing the bridge! I have crossed it many times but I never knew how it was built. So cool!

Okay okay, so now I fully understand why cisco went with that logo. What a phenomenal engineering!! Hands down the best looking and stunning bridge out there imo. 👏❤💯

Maybe I'm biased, but I don't understand how people complain about the fact that we don't make beautiful monuments anymore. Building something like this bridge is a far more impressive and inspiring feat of the human species.

Wonderful, well calculated basics on this Golden gate bridge. Great info for civil engineers and a great experience for the passengers on this bridge. Alexander, lndia.

Absolutely incredible and an underappreciated engineering marvel. I am impressed.

I really am appreciative of the work and effort of everyone who made that bridge. Also I appreciate the hard work it took to make this video as well. It was super informative and showcased everything perfectly.

bro i wasnt expecting a 15 minute video of physics and the engineering of a bridge

Not only that it is tough, the design is really elegant & looking contemporary up to this modern day. Iconic, forsure! Those are true masterbuilder 🎉

A well engineered vlog that I have seen on civil engineering. Thank You for sharing it.

Wow. I didn't know the bridge was such an impressive engineering feat. It deserves its place among the Wonders of the (modern) World. And they did all of this without computers.

5:30 I see what you did there.. very clever.

This is the amazing video i have seen in a long time. And also hats off to the engineer behind the golden gate bridge "The Joseph Strauss"

I was always waiting for a civil Engineering video since I am a Civil Engineering student. Thankyou lesics for this. Joseph Baermann Strauss was a great Engineer. Respect to him 🙏.

What an amazing video describing this engineering marvel. Thanks for the incredible 3D work you did, it brought it to life.

It's incredible what human beings are capable of. We must appreciate all the magnificent work people in the past have made for our pleasure

Very thoroughly explained. Thanks for taking the time to create this content.

Being a civil engineer I really aspire to do such types of projects.

2:21 me enabling creative mode on a world that i said i was going to beat the enderdragon on

I love the pauses. It makes me feel like I'm watching adult Dora, and makes it apparent that I cannot actually answer any of these questions.

This might seem crazy but I actually cried appreciating the genius of human engineering. A lot really do go underappreciated! Your videos make me appreciate life a lot more.

0:32 idk why I found the guy running down the bridge so hilarious

Be honest, you watched this because you saw what happened in Baltimore 💀

Ahhh.... always wanted to know HOW this bridge was built. I read some descriptions but as a non-engineer, need to see a visual representation. Especially the portion about laying the foundations and building the tower. Thank you!

my grandfather was an engineer for the port authority in New York City, and worked on many famous bridges here(the gw, throggs neck, Verrazano). videos like these make me appreciate the work he did here even more.

Awesome that they took the time to animate all of this, nice video and thank you 🙏🏽 😊

For the longest period I have been watching different KZfaq videos in regards to the construction and this is best I have come across! I now understand

Man the animation keeps getting better and better. Feels like I time travelled to the construction of the bridge...

it wasn't just Joseph Strauss, there was a talented team of engineers and architects involved in this, give credit where it's due.

Thank you for such an incredibly well explained video!

Thank you for the animation, it helped visualize things rather than just saying words and plain picture

No doubt it is an engineering marvel. This makes me proud to be a Civil engineer student. This motivates me to study harder. While studying I just imagine that this 5 page numerical defines the lives of thousands of people who are going to use it.

I love this animation! Why better than B-roll of stock photos of the same thing over and over

Can't even fathom how you design and compute all of this by hand. On paper. Amazing

I've seen a short clip on Facebook, and now I'm here. Very interesting, hits the dopamine spot

Man, this is really impressive how they thought of all these problems to fix to build such a bridge

You are amazing guy Please make a video about "Howrah Bridge" Howrah Bridge - longest cantelever bridge

Really gives you a better appreciation for the massive amount of thought that goes into our infrastructure.

I live in lisbon, and i am always stunned by the proces of building a simular bridge and what comes with it. It's amazing.

i want an explanation like this FOR EVERY SINGLE THING

I wish there were videos like this when i studied engineering 5 years ago

It is so incredible that they were able to build this bridge with no modern technology. Huge respect for those people

Would this bridge survive a cargo ship bumping into it?

Watching this video and gaining such information makes me even more happier being a civil engineer.😊

Golden Gate was interesting but what about The Howrah Bridge of Kolkata? It was also a really incredible project.

Thank you so much for the awesome video.

Great video and amazing they pulled this off given the technology available

A master piece of engineering and architectural design

The foundation part is really intriguing. Its unbelievable what humans can achieve.

This video is fantastic, seriously AAA quality. Damn strait I'm gonna be a Lesics member!

This was great. So much better with the animations.

Engineering is interesting, interesting is engineering! Thanks for this amazing creation, not everyone is so fluent in making complex things seem easy!

He's a genius and also protected the workers so well

Crazy engineering to give way for automobiles. Great👏🏻
