| Alasdair Binns shared Stuart Cameron's post Two icons of Scottish Engineering heritage, paddle steamer Waverley passing under the Forth Bridge - note the commuter train on the left side helps to give you a perspective on the size of the bridge - if you haven't seen it ' in the flesh' |

| Bridges Now and Then posted "The upturned hull of the Imperial German Navy Kaiser class battleship the SMS Konig Albert which had been scuttled at Gutter Sound, Scapa Flow following the armistice at the end of World War One and then raised passes under the Forth Bridge towed by tugboats on her way to being scrapped at the Metal Industries Ltd shipbreaking yard on 5 May 1936 at Gare Loch, Faslane, Scotland, United Kingdom." (Photo by Fox Photos/Hulton Archive/Getty Images). Gavin Mcadam: Wee correction, folks: the wreck was towed to Rosyth for breaking up. Rosyth is close to the Forth Bridge, seen in the picture, and is on the east coast of Scotland. Faslane is on the west coast of Scotland, miles away. |
Among the most famous bridges in the world, the Forth Rail Bridge was the longest cantilever truss bridge in the world when it was completed in 1890. The 1917 Quebec Bridge in Canada is the only bridge to have surpassed its span among cantilever truss bridges. Sir John Fowler and Sir Benjamin Baker designed the Forth Rail Bridge and construction began in 1882. It is unique for its use of massive tubular members and is also one of the first large-scale uses of steel in bridges rather than wrought iron. [Historic Bridges]
This is another significant bridge that is so famous that I haven't bothered to document it. But this construction photo post allows me to add to what you can find by Googling.

| Glasgow City Archives posted #OnThisDay [March 4] in 1890 the Forth Rail Bridge was opened by the Prince of Wales. Built by Sir William Arrol & Co, the bridge took seven years to complete and at its peak employed approximately 4,600 workers in its construction. It was the largest steel bridge in the world at the time. Ref: T-HL294 William Craig: 57 Men lost their lives during it's construction. [There are many more interesting comments.] Alasdair Binns shared |

| Chris Stewart commented on William Craig's comment This is the monument built underneath the bridge on the North side, naming all the men who died and their trades, the structure from underneath is amazing. |

| Bridges Now and Then posted Title-"Forth Bridge - Fife S.W. skewback & tubes in construction, 7 Sept. 1886" "Description Photograph of a 'skewback' and tubes in construction. Relative proportions of the men and their work in this view afford an admirable illustration of the remarkable dimensions of the Bridge. The five tubes shown represent the bottom members, the vertical column, and two struts 8 feet in diameter. The bottom member on the right hand side is part of the first length of the span, and is continued at this angle until it meets first tie. Surrounding one or more of these tubes will be noticed a cylindrical cage composed of angle iron, hoops and bars, and protected by a fine mesh wire netting. To the upper part of these cages were bolted iron straps passing up and connected to the lower side of lifting girder, so that when the latter ascended it carried up the cage along with it. These cages, within which all the riveting of the vertical columns was effected, were designed to ensure the safety of the workmen, for which purpose they proved invaluable. The depth of each cage was sufficient to admit of a 16 feet plate being riveted up without a hoist, the working space allowed between tube and netting being 4 feet. The difference of shades upon the horizontal tube in the foreground of picture is only due to the fact that it was being used at that date as a suitable surface for testing various samples of light coloured paint.

| Charlie Gilbert posted Late 19th century railroad bridge across the Firth of Forth into and out of Edinburgh. Paul Alan shared [Some comments indicate that this is the first major structure in Britain to be constructed of steel. Its contemporary, the Eiffel Tower, was still built with iron. Some comments claim this bridge was the replacement for the Tay Bridge. But I doubt that since this bridge was over the Firth of Forth estuary and the Tay Bridge was over the River Tay.] |

| David Denenberg commented on Bob's post The original image in this post has a bit of forced perspective. The Forth bridge had the longest main span of any bridge in the world when it was completed and still has the second longest cantilever spans (after the Quebec bridge). Normal perspective from a distance, taken by me in 1995: |

| Toilets With Threatening Auras posted Francisco Lacy shared David Denenberg That’s the famous Firth of Forth rail bridge. I was able to take some track-level photos in 2019 but didn’t spot this particular accommodation. https://www.bridgemeister.com/pic.php?pid=2721 |
This is just before it goes under the south tower.
