Forth Railway Bridge over the Firth of Forth near Edinburgh, Scotland (United Kingdom)

"This railway bridge, spanning the estuary of the Forth River in Scotland, was the world’s earliest great multispan cantilever bridge, and at 2,529 m remains one of the longest Innovative in style, materials and scale, the Forth Bridge is an important milestone in bridge design and construction during the period when railways came to dominate long-distance land travel."
