I remember vividly as a teenager journeying several times by train across the Forth Bridge when I lived in Aberdeen, and seeing the gradual construction of the Road Bridge at various stages in its development. Work started in September 1958. When I was 16, my mother drove my brother and me to North Queensferry in her Morris 1000 to excitedly join the queues of vehicles which would be the first to cross the new bridge on 4th September 1964. The original toll for crossing the bridge was 2s 6d (12 and a half new pence in today's currency), and the most recent toll of One Pound was eventually abolished in February 2008, when the Abolition of Bridge Tolls (Scotland) Act came into force, covering all road bridges in Scotland.

@@TheB1M Any chance you could do a video sometime on why modern suspension bridges such as the Queensferry one are designed the way they are and why they are an improvement over traditional suspension bridges such as the first forth road bridge and first severn bridge? The latest designs seem like such a more obvious, easy to construct robust and better design with longevity in mind so I'm wondering why when they built the first forth and severn bridges they didn't use this design?

It's funny, I don't have any real life connection to any of these bridges, but I somehow managed to learn about both of them completely independently. I've driven over the old road bridge hundreds of times in Euro Truck Simulator and have spent hours studying the history and construction of the rail bridge to help me with designing a fictional bridge in a story. They both feel like familiar landmarks to me at this point, yet I had no idea they were right next to eachother until I saw this video.

@videowilliams 3 года назад

I like the fact that "building for the ages" has returned to the Firth of Forth as a guiding principle. It sounds as if they expect to take the high-maintenance 20th Century road bridge down at some point while the 21st Century one, like its 19th Century forebear, has been designed to last. There used to be a play on the slogan for Mercedes Benz- that they were "Overengineered like no other car"- but if you're building giant bridges, overengineering seems to be, long term, the way to go. I never get over how enormous that original one is, and how heavily built, in order to handle just 2 rail lines. But they wanted one that would never ever fall, unlike the disastrous one before it that collapsed one windy night with a train aboard, in the infamous Tay Bridge Disaster (1879). A bit surprised you didn't mention that actually 🤔

@syncmonism 6 месяцев назад

The Forth Bridge is so well built in large part because in the stage when different proposals for its design were being considered, a very recently built and long rail bridge nearby had collapsed when a train was crossing, killing everyone. Suddenly it became a lot easier to justify a higher cost project. Everyone realized the importance of not trying to make it as cheaply as possible, of not cutting corners, and of being very strict with the quality of the materials being used during its construction. Sadly, safe working conditions still didn't have a very high priority, and a shocking number of workers died. 73 deaths have been attributed to the construction of the bridge by historians due to various causes.

Oh dear! All the jibes at reversing Firth and Forth (an accident waiting to happen) Of course the Fourth of the Firth is a new description that fits the Kincardine Bridge which was inevitably overshadowed, even before it was opened, by the grandmother of all railway bridges. This is of course compounded by the nearby Clackmannanshire Bridge which leaves a right mouthful of Firth, Forth, Fith and Fourth.

@andro7137 3 года назад

Perhaps Sir William Arrol deserves just a little credit for his ingenuity in building the railway bridge? I was surprised to hear the 1964 bridge described as being 'cutting edge'. Its design was approaching the end of the line for the early generation of that type of structure.
