This long-span suspension bridge is 2. Its towers are over metres high and hold 49, km of wire in the two cables which take the weight of the suspended deck. Following the opening of Queensferry Crossing, the Forth Road Bridge is now dedicated to public transport, cyclists and walkers.
Queensferry Crossing. The Queensferry Crossing opened in and, at a length of 2. The bridge is destined to become the main route for vehicles travelling between Edinburgh and Fife. You can learn more about the building of the bridges at Queensferry Museum in South Queensferry.

An enduring icon of Scotland Opened in , the Forth Bridge is a Scottish icon that is recognised the world over as the most famous of cantilever designs. Forth Bridge Facts and figures.
Forth Bridge World Heritage Site. Wages on the project were also above average for all classes of worker. During the seven years of construction, work was carried out from almost feet below the surface of the water to over feet above the surface. The first three years were spent building the granite piers on which the bridge was to be supported. This was done by sinking caissons — great wrought iron cylinders — to the sea bed and pumping them out so that men could work on the floor of the Forth, creating foundations and building up the piers.
This was dangerous and unpleasant work and, in two of the caissons the depth was such that water had to be kept out by filling the working chamber at the bottom with compressed air, the men going through air locks to get to their work.
Work on the superstructure got under way in and the growing structure became a site of wonder as it grew out from the piers, growing first upwards as the towers were completed, and then outwards as the cantilevers stretched out to meet one another, seemingly defying gravity as they did so. The bridge was completed in December and the following month it underwent load testing.
Two trains, each comprising three locomotives and 50 wagons loaded with coal weighing in at a total of 1, tons for the two — twice the design load of the bridge were driven slowly out onto the bridge, stopping frequently for measurements to be taken. In February the first complete crossing of the bridge took place, with a train carrying the chairmen of the various railway companies involved. The Briggers, is the name given to the thousands of men who built the bridge.
They were the men who toiled on a daily basis in hazardous conditions, that we would not comprehend today. Imagine being in a rivet cage hanging from a work platform hundreds of feet above the icy Forth.
Teenage rivet boys and sixty year old ex-shipyard workers faced these conditions every day. The book tells of Saturday night brawls and Sunday shebeens and of the countless visitors from the Shah of Persia to pleasure steamer trippers. For the first time the faces of individual Briggers emerge from the shadow of their bridge, thanks to the latest digital technology and the collection, recently acquired by the National Archives of Scotland, of the work of engineer Evelyn Carey, the only person officially allowed to take photographs on the bridge.
The painstaking research by four local historians to uncover the names was the inspiration for this book. It arose from an apparently simple request from the Forth Bridge Memorial Committee who sought to give the men who died permanent recognition by erecting monuments to them on either side of the Forth. A search through official records for a list of names drew a blank.
The team then spent years of their spare time scouring contemporary newspaper accounts, death certificates and other sources to compile the first-ever list of the names of the individuals who died. During their trawl they amassed the wealth of detail about life and death on the bridge that is the basis for this book.
The event marked the end of a 10 year restoration project on the rail crossing over the Firth of Forth. The Forth Bridge has three double cantilevers with two ft suspended spans between them, at the time the longest bridge spans in the world.
As required by the Admiralty, the rail level is ft 46m above high water. Each of the towers has four steel tubes 12ft 3. Their foundations extend 89ft below this into the river bed, making the total height from foundations to the top of the towers metres. The total length of the bridge, including its approach viaducts is 2, metres. The main structure itself measures 1, metres portal to portal. It incorporated 6. It was designed to withstand a wind force of 56lb per square foot.
Building the foundations for the vast towers started with the construction of huge caissons which were built on site and sunk using compressed air. The first of the caissons was floated into position on 26 May By all the foundations were in position ready to take the steelwork. Thanks to the organisation and inventiveness of William Arrol, the bridge was completed in November , just 6 years after work started although at the time the weather was particularly cold and Arrol had to wait for milder weather conditions before the enormous structure expanded sufficiently for the final rivets to be inserted.
Total Length 8, Ft or 2, m, 1, for the main structure. Longest span 1, ft m either side of the center cantilever. Clearance over high water ft 48 m , Dictated by the Admiralty, for naval vessels passing below.
