Thank you - now I can show this to my wife who thought perhaps I (a civil engineer) had experienced a stroke as we approached Edinburg in a tour coach and I exclaimed "That's the Forth Bridge" She replied, "Where are the first three?", I said, "No, Forth, it crosses the Firth of Forth" at which point she decided I had lost the power of speech. I was, to a degree impossible for an accounting major (her) to fathom, completely geeking out about a civil engineering wonder which I had read about, but was only beginning to appreciate in real life. This will help her understand.
If someone told me this bridge was 10 years old, I’d believe them. So I’m having a hard time imagining just how futuristic this bridge must have looked when it was new!
I think it's a testament to the engineering that went into the structure. Many modern bridges use the same design elements because they work really well. I'd imagine that it *did* look really advanced when it was first completed because it was!
I live less than 15 miles away from this bridge. It is a really impressive structure, and you just can't understand the scale of it unless you see it in real life. Pictures do not do it justice at all.
Growing up we said the same about the George Washington Bridge in NY. "You start painting from one side and by the time you're finished, youre starting all over."
Its supposed to take 7 years to paint the bridge from side to side and the paint is made from a special structure to help with the salt erosion of the sea
The design of the Tay bridge involved cast iron. While very strong, it is not very tough and will encounter brittle failure when overloaded. That, combined with the massive cross-sectional area exposed to wind loading, ultimately caused the bridge to come down. The design was essentially eyeballed.
What I love about the Forth Bridge (aside from being generally awesome) is that it's a visual lesson in structures - all the main compression members are tubular (the best shape to resist buckling), all the main tension members are lattice trusses. Almost without exception. Also, aesthetically, the way the curve of the bottom chord of the cantilevers flows into the horizontal deck of the suspended spans gives it an elegance and a visual unity that many large cantilever bridges lack.
A feat of engineering for certain, and the best part is, there's a side-project video idea to this, and that's repeatedly painting the bleedin' thing for decades until they recently coated it with a much longer-lasting paint... :D
The first time I ever heard of the Forth bridge, being as I live deep in the heart of Texas, was on a mudlarking UA-cam video. They really didn't go into the history. THANK YOU!
An interesting look at a bridge I've crossed many time, however. I feel on this occasion your writer did Sir Thomas Bouch a bit of an injustice. Yes he was involved in the designs of ferries having introduced the first roll-on roll-off train ferries in the world. However, railway engineering was always his forte. He had a successful career in bridge design having designed several bridges across the north of England and Scotland. I also believe he was also part of the team that developed the Caisson
That and the Tay Bridge wasn't finished to his designs. The number of supports was reduced the quality of some of the metal was of questionable quality for cut cutting reasons. Its entirely possible his original design with appropriate materials would've stood through the storm.
Near the road bridge there was a hotel and in the grounds was a steel mock up of the construction demonstration. Two or three of you could sit on this while another took your photo. I do not know if it still exists today though.
It's like Bridgefest visiting North / South Queensferry; 3 Bridges; this rail bridge, to left: the 1960 Road suspension bridge (Now local traffic only) and the new Motorway Cable Stay Bridge.
Still my favourite Civil Engineering project in the U.K I remember going along the Forth road bridge quite a few times visiting family in North Berwick.
Previous experience making ferries, now make an record bridge, and yes he should stuck to ferries. And loved the 3 guys in the image, ok that is how it works.
I've always admired this mammoth construction, and wanted to drive over it , then as I live in London wasn't able to visit until I went to fort William, so in 94 I decided to drive there from Ben nevis not realising that it was only a train bridge, the road bridge was about a mile away the bank. I should have done my research first lol.
I live in South Queensferry, which is on the South end of the bridges. They are the view from my living room window. They are an amazing sight, especially lit up at night. The middle bridge, the Forth Road Bridge, is by far my least favourite. The old one, as seen here, is a glorious beast. The new bridge, the Queensferry Crossing is rather beautiful in a very different way. The old road bridge is not particularly nice looking and it's a favoured suicide bridge. It's the most depressing thing about living here - any time you hear a helicopter, you know the chance is high that someone has just taken a dive. But the village is amazingly pretty, all in all, I'm very lucky to live here.
Its a fascinating bridge and one I've spent many times chilling beside, also been lucky enough to get on top of it which was an experience! Great to see you cover this big beautiful icon of Fife 😁👍
A stunning bridge…. Always a winner when we stop if there for views when doing most tours out of Edinburgh….. can also see it off in the distance from my house.
One of their pieces of ingenuity was using an island to support the center piers. I've seen a video about the Tay bridge which states that there were survivors. The Quebec bridge, built using the same concept but with only one span, collapsed during construction.
Recent discovery about the Tay bridge disaster found that the section which disappeared during the event had been blown off its barges during a previous storm. Instead of building a new section, the damaged one was salvaged and erected with a twist in the structure, compensated for by the insertion of triangular plates at track level. Trains passing this point experienced a side step, lurching left to right (vice versa depending on transit direction) The combination of side step, speed and high wind derailed the train, striking the triangular struts and dislodging the damaged section and adjacent sections!
I've been to Scotland many times and was delighted to get the opportunity to cross this bridge on one of those visits. As we crossed, I thought of the great scene in Hitchcock's 39 Steps when Mr. Hannay pulls the emergency cord as they cross the bridge and escapes by hiding behind one of those massive steel piers. He later calls out the bridge as a tribute to Scottish engineering, which it truly is.
I kept thinking “what happened to the first, second, and third bridges,” until I realized it’s not spelled “fourth” so it has to be the name of the geographic location 🤣
What a gorgeous bridge! I had heard of the Tay Bridge because of the disastrous collapse, which has always fascinated me. But wow, how did I not know about the Forth Bridge! I have crossed the GGB many times. One thing that makes it so striking is it’s color… a color that isn’t so common for painting bridges. It appears the color of the Forth Bridge is very similar to the GGB’s international orange. (It’s really more red or brown than orange, but they call it orange). I am wondering if the GGB designers were looking at the Forth Bridge and were inspired. That color really sticks out through the fog that so often surrounds the bridge. Nice documentary, thanks, Simon and crew. Now I want to go and see this bridge, and the Tay Bridge as well!
I live in the nearest city to the bridge ( Dunfermline). most of the time when I go to Edinburgh, I go by train. This is mostly due to the great view you get of the ocean and surrounding area. The bridge also has a great history, something you missed out. In ww2 Luftwaffe bombers tried to destroy the bridge but failed due to a small defence of aa guns on the island beside it.
i live in edinburgh and visit my dad in fife each week, every time i see the forth bridge i am amazed by it, the photos dont do it justice with how large and impressive it really is
Every time they think traffic is a bother they'll be adding another. Given enough time we'll probably end up having soo many bridges across the forth that you'll end up with a detour that goes entirely on land.
@@OnlyGrafting the new road bridge isnt for traffic, its for safety as the old road bridge was becoming unstable, the old one got shut as soon as the new one opened
lovely bridge to see. I have been over it many times by train and it is 'nothing special' which is just what you want from a bridge. The less drama in a river crossing the better.
These iron bridges need to be painted continuously in order to prevent them from rusting away. Unfortunately, the current owner of the Quebec bridge has decided to stop painting it, so we may not have it for much longer.
Interestingly the phrase "Painting the Forth Bridge" became a colloquialism for an unending task. However in 2011 the bridge was painted with a special epoxy paint meaning the bridge now only needs to be painted every 25 years. Hopefully the owners of the Quebec bridge do something similar.
This will sound really stupid - I live about 30 mins away from the bridge. Until I was about 12, I thought that trains went over the top, like a giant red rollercoaster
I can hardly believe you omitted possibly the most iconic and legendary aspect of the Forth Bridge - that is the one about its painting, which has to be started again just as soon as it's been completed (owing to its length and sheer size)!! It's this single context in which us Brits most often refer to the bridge!!!
master piece of iron work, yes cad, Cardboard Aided Design template, that's about it, and lots of intelligence, could you imagine what these tradesman could achieve today in speed construction with the machines of today and posh all weather gear, every time a pass that bridge it reminds me of 3 prehistoric brontosaurus dinosaurs wading across the water
If I'm in Astoria and need to cross the river, I would rather go downstream and ride the ferry or go to Portland and cross there because the Lewis and Clark Bridge is even worse, in my eyes. But as a video, it's a great idea.
Absolutely excellent episode! I had never heard of this before. The historical photographs were amazing. Razor sharp, and really showed their concept effectively
Having grown up in the Upper Peninsula of Michigan, I would absolutely love to see you do a story on the Mackinac Bridge, a world record breaking bridge upon its completion, and one of the most fine-looking bridges out there!
It seems like some recognition of the longevity of the Forth bridge is in order. In a world where bridges are regularly being demolished/replaced that have only stood for 40 or 50 years, this bridge is not a candidate for replacement and is, it seems a part of the landscape. I leaves one wondering why more modern structures lack permanence. Have we forgotten how or have we just lost the will to things that will last?
I'm a bridge engineer and I love that bridge. But I learned there was a lot of criticism of it, and I can't get the imagery of that criticism out of my mind. Some called it an ugly steel monster that lacked curves and was very industrial. Rebuilding something like the Tay Bridge properly might have looked better. And I kind of agree. But sstill, longest cantilever, relevant 130 years later, iconic.... I'd love to go see it.
I live practically underneath the south end of the bridge. She's a glorious beast, anyone who thinks she's ugly has not met her, especially lit up at night 🙂
Lacked curves? Look at the way the curved bottom chord 'flows' into the suspended spans - pure artistry IMO, and it makes the bridge a unified whole, visually. Most big cantilever bridges don't have that and look like a random collection of shapes stuck together. As for the Tay Bridge (original and replacement), it's just a long string of box girder spans - nothing visually noteworthy about it.
@@cr10001 I suppose the criticism is relative. Curved as opposed to stone arches or chain link type bridges common at the time. Apparently some didn't think it was all that graceful or beautiful structure at the time it was being built.
@@patrickgallagher9069 Good point, and I do recall reading that there was some criticism of its appearance and that it could be improved with decoration. How would you 'decorate' the Forth Bridge? :) Although (at the time) probably no arch or suspension bridge could have spanned the Forth *and* carried the loads (flexibility of the deck was a big weakness in railway suspension bridges). For complete absence of curves, there was Robert Stephenson's wrought-iron 1850 Britannia Bridge across the Menai Straits, and the similar Conway Bridge. Reminds me of Greek temple architecture. The original intention was to include suspension chains to share the load, but after model testing the box girder 'tubes' were found to be strong enough by themselves. Though I seem to recall reading that Stephenson only provided for the chains to soothe the doubters and fully expected that result. (Tragically, the tar-coated (for corrosion control) roof of the tubes caught fire in 1970, and the tubes were damaged beyond repair. 120 years of steam locomotives failed to set it on fire, some idiot kids with a burning torch did. Which is why the bridge is now a steel arch with the same high piers. I can't say it looks bad, but nothing like the elegance of Stephenson's bridge.) But Conway Bridge is still there, after 170 years. Victorian engineering was designed to last.
@@cr10001 One thing that I think makes bridges unique is often times their structural demands define their shape. So, I think adornments on a bridge distract from their inherent beauty. And that is the case for the Forth of Forth. So, I suggest nothing could be or should be done. The bridge' structural demands are evident in its shape, so it is all that it should be, perfect the way it is.
In the 1980's I drove on the car bridge that is now close to the Forth. It was a pretty impressive and large bit of metal! I wished I could have crossed it, but trains only.
Today there is a new road bridge (Queensferry Crossing) beside the old road bridge (just used for taxis and buses), so you have three bridges all in use and all built in a different century from each other! Probably unique in the world on that fact alone.
It may be a little provincial, and it may be just because I'm a former Chicagoan, but did you ever think about doing the Deep Tunnel project? What about the Big Dig in Boston? Again, sorry if those are too small scale.
Mackinac Bridge would also be an interesting mega/side project or dare I say a Giographics of the Great Lakes in North America, sinking of Edmond Fitzgerald.
Thank you - now I can show this to my wife who thought perhaps I (a civil engineer) had experienced a stroke as we approached Edinburg in a tour coach and I exclaimed "That's the Forth Bridge" She replied, "Where are the first three?", I said, "No, Forth, it crosses the Firth of Forth" at which point she decided I had lost the power of speech.

In the 1980's I drove on the car bridge that is now close to the Forth. It was a pretty impressive and large bit of metal! I wished I could have crossed it, but trains only.
Thank you for doing this
Today there is a new road bridge (Queensferry Crossing) beside the old road bridge (just used for taxis and buses), so you have three bridges all in use and all built in a different century from each other! Probably unique in the world on that fact alone.
Walked over that redundant bridge today - surprising how much it bounces when just a bus goes over
Buzz Killington loves a good story about a bridge
One of the most beautiful bridges in the world .
how about a video about the rebuilding of the San Francisco Bay Bridge after the 1989 earthquake?
You didn't mention William Topaz McGonagall's poem on the destruction of the Tay Bridge.
Simon, a metric tonne approximates to a long ton. Talking about short tons will just confuse people. What do you mean, there's more than one?
The History of hydraulics would be a really interesting video- keep it up guys!
Now that you've mentioned it. You have to do the Québec Bridge.
Perhaps do a mega projects video on the EADS Bridge in St. Louis MO.
After your F1 video you should cover nascar similarly, it just turned 74
It may be a little provincial, and it may be just because I'm a former Chicagoan, but did you ever think about doing the Deep Tunnel project? What about the Big Dig in Boston? Again, sorry if those are too small scale.
Truly magnificant, but admittedly not quite as impressive as the Fifth Bridge, which (naturally) crosses the Firth of Fifth.
You should do a video on the Chesapeake bay bridge!
You should do the Québec bridge, fell in the gap twice during construction!
the bridge fell or you fell in the gap i am genuinely confused
@@catalintimofti1117 considering it was opened in 1919, it is the bridge that fell, twice during construction
Mackinac Bridge would also be an interesting mega/side project or dare I say a Giographics of the Great Lakes in North America, sinking of Edmond Fitzgerald.
For megaprojects or sideprojects - the su 47 berkut
I will always remember this bridge as the bridge between San Fierro and Bone County lol
Have you done the Akashi Kaikyo Bridge in Japan? That's the longest suspension bridge in the world.
Read the video title and really wanted this to be about Bridge 4
A Megaproject on the Quebec bridge (pont de Quebec) would be great. It has a veryinteresting an tragic history
Hey Simon, I would love it if you would do an episode/episodes on Bagger 288/293 and or Bingham Canyon copper mine!
I took my 3 year old to deep sea world which is underneath the rail bridge this summer. He was more fascinated by the bridge than the sharks.
