Golden Gate Bridge | How a Wonder was Constructed?

[@SabinCivil]

Your support matters a lot for survival of my channel - www.patreon.com/sabins , I will be truly grateful for your support today. Thanks Sabin Mathew

[@eyebeebak]

This is exactly the video i've been looking for for the last 20 years. Most just talked about how the bridge above water was built, but none talked about how the underwater foundation was built. Thank you.

[@captaincucaracha]

Crazy how you’ve been looking for this information for 20 years but I simply came across it via the KZbin recommendations

[@tylerlosleben4560]

I just can't imagine the digging beneath to sink it more into the bedrock. Like can you imagine how scary that would be digging as it sinks more and more. So much respect for those workers...

As a retired Union Ironworker of 60 years I would like to emphasize the fact that STEELWORKERS make the steel that IRONWORKERS fabricate and erect in steel structures. Both professions are honorable in their own right.

This video means so much to me thank you. My great grandfather helped assemble the bridge and my granpa walked across it with him on opening day. My grandpa gave me a broken rivet that his dad kept and when i see it i remember all the good memories and knowledge he gave me.

[@evansgate]

I take lots for granted and the amount of manpower, brainpower, and ingenuity needed for a project like this is astounding

[@jeremyk9000]

The workers involved in this construction must have had balls of steel. What an incredible feet. Thanks for the detailed information!

[@Gigatless]

Balls are neither relevant or impressive here. Knowing the modern construction workers the most impressive part is how well they did their jobs so this ultra massive construction is still in use, while your local construction companies can barely build a two story house that would last longer than 50 years.

[@jeremyk9000]

@@Gigatless you've obviously never worked at heights, nor confined spaces, nor underwater. That's incredibly dangerous work. It absolutely takes balls. The engineering is equally impressive given how long the structure has stood.

[@Gigatless]

@@jeremyk9000 I did work at heights once and the biggest concern was always "are my surroundings safe enough for me to be here". If the construction work is being done right the workers are able to feel less stressed about being there.

[@enkercodm9506]

Probably never gonna be seen but thank you construction workers who put up with hell so we can have modern architecture

[@Kurtdog63]

I used to jog across this bridge back in the 1980's while attending language school in the military. I remember they had lane changes for morning and evening commuter traffic. They had tall plastic traffic pipes they would shift over to allow more lanes for morning or evening commuter traffic. They also had traffic lights that changed from morning to evening based on the direction of traffic. It think the lights had a red X lit up for lanes that changed direction not allowing access from that direction in the mornings. It would change to green in the evening. Muir woods with the giant Sequoia trees is not far from this bridge. On a side note, the city is/was known for its trolley system, but never road a trolley the entire 7 months I was there because the trolley system was down for a major overhaul that entire time.

[@GamebossUKB]

Derrick was truly the builder of all time.

[@michaelb.42112]

This is an absolute miracle, and living in the Bay Area always amazes me that this and all the bridges in the area are modern marvels. Like Arthur C. Clarke said, technology we don't understand is indistinguishable from magic. EDIT : When I see famous black and white photos of the workers on their lunch break hanging casually hundreds of feet above New York City during the construction of the Empire State Building, photos of the Golden Gate Bridge workers, and other 20th Century marvels I think how those 18 and 19 year old men were just kids, and they are the same generation who lied at 17 to appear 18 in order to fight and die for this country in Normandy, France on D Day. Today, 18 and 19 year olds need coloring books to cope with the stress of the long line at Starbucks.

[@Ruby-Rainbows]

and the historical men and women who slept in fields through sun and storm alike, with nothing but sword in hand and cloth in tow would've casted an ill gaze on all those brave engineers for sleeping in their nice modern beds after. the stone jockeys carrying boulders to inlay the foundation of their kings castle must laugh at the very idea of a hard hat. and im sure the historical men and women heaving countless materials with nothing but human leverage would consider using a crane as weak. The worst experience you've ever had is simply the worst, and in that moment contemplating anyone else who has ever been through a lesser or greater struggle doesn't matter. Someone views the inception of the crane as lazy while another views it as ingenious. Humans will always seek to lessen their burdens, and the burdens will always lessen. The imact and implications of those burdens are equivalent in their effect on the person suffering from them, and judging one another based on percieved differences in the weight of a struggle is a concept grounded in ill intent, insensitivity, and ignorance. We are all born alike and if a simple difference in opinion is enough to condemn someone to suffering, then those who consider beds a luxury, and warm food a gift, might sit idly by during your time of need simply because they can't empathize with a struggle they deem as "lesser". not to unintentionally highlight the unempathetic and narcissistic takes some people have on life 🙄

[@creativecarveciteclimb5684]

goofy run

[@TheLiamster]

I wish the bridge was built with two decks with the lower deck having a railway for BART to run on. It would be so cool to see trains going over the Golden Gate Bridge

[@gotrees4]

Fun fact: Trains used to run on the bottom deck of the Bay Bridge until the Key System had to shut down. The Key System connected the East Bay and SF for years before monopolistic and predatory practices by the auto industry forced it (and other public transit networks across the US) to shut down in the 50s. You can look up the GM streetcar conspiracy for more info!

[@michaelb.42112]

@@gotrees4 WOW never knew !!!

[@LaggerSVK]

look up famous portugal 25 de Abril Bridge that is inspired by Golden Gate bridge

[@scarx4181]

There have been proposals for that in the past and even an entire separate roadway underneath, but the truth of the matter is that the GGB is getting old. You can't go below the deck just south of the north anchorage(there's a gravel parking lot about 15 feet below the bottom of the bridge there) but if you take a pair of binos on the trail far below and look under the bridge it's looking pretty nasty these days. There's only so much you can do just by slathering more paint on. The bridge is a good 2/3rds through its lifespan at this point so major investment like that just doesn't make a whole lot of sense. I'm a cop by trade not an engineer so I'm not qualified to make any judgements on it, but I did work there and while the towers are mostly in good shape(bit rough down towards the water especially on the south tower) the actual deck structure just wasn't looking great to my eye.

[@sunnyshines2691]

As a gsw fan from India this video gives me a chill vibes😅

[@snakefinger]

Thanks!

[@martyburbank3356]

The lack of SCUBA tanks is not why the divers used surface supplied air. If they were building the bridge today they still would use surface supplied air. SCUBA tanks are rarely ever used for commercial diving. They just do not allow the divers enough bottom time. Surface supplied diving not only provides the divers with unlimited air, but the umbilical can also provide communication, heat, and a secure method of recovering an injured diver.

Fun fact, the Golden Gate Bridge is continuously painted with the international orange paint. They start and one end and work their way to the other end. This takes 3 years to complete. By the time they are finished, they need to start all over again.

[@scarx4181]

Not really, it's usually just in a maintenance cycle where they do touch up paint on the more problematic areas. They spend more time inspecting than actually painting it. Source: I worked there for a couple years.

[@scarx4181]

@@andreabonacossa8709 Depends on the weather, on a clear day it's pretty magnificent. I didn't like going up there much, not a huge fan of heights, which is somewhat ironic since walking the catwalk on the north side of the bridge under the deck(which is still 200ish feet off the ground) was a daily task.

[@林楷晟-d1y]

these marvels are the reason i chose engineering as my major

[@WDCallahan]

Two questions: How did they keep from blowing up the placement tubes? And if the divers used high pressure hoses, would they not go flying backwards like a rocket?

[@Akuseiko]

I would imagine clever design to direct the blast energy for the tubes, as for the divers, weight. Boots weighing in at 20 lbs each, probably around fifty or so pounds of brass, leather and rubber for the suit. Plus lead plates for added counter-buoyancy. 30-50 pounds of diving helmet. A 1930s diving suit is a good 190+ pounds. Once those guys plant their feet and lean into it, they are going precisely nowhere.
