The Forth Bridge: An Incredible 19th Century Achievement

[@richsarchet9762]

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.

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!

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.

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.

[@jonnylumberjack6223]

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.

[@VDPEFi]

Images of this bridge always remind me of my dad and his childhood sailing there and our holidays to the Queensferry's, very evocative.

[@cheyennedogsoldiers]

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

[@TheKazragore]

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.

[@rlinwa723]

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 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!!!

[@oddsandwindsocks5905]

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.

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.

[@californiahiker9616]

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!

[@georgefuters7411]

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'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.

[@cr10001]

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.

[@patrickgallagher9069]

@@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.

[@cr10001]

@@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.

[@patrickgallagher9069]

@@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.
