The Forth Bridge is a cantilever railway bridge across the Firth of Forth in the east of Scotland, about 9 miles west of Edinburgh. It is an iconic structure and is a UNESCO heritage site. During the Second World War it was the subject of the first bombing raid by the Luftwaffe over British skies. Thankfully the RAF and their spitfires defended the bridge, and it still stands today since its opening in 1890. There are some more interesting facts about the bridge at the Forth Bridges website.
We just don't build structures like this anymore. The Victorians really didn't build anything with half measures. Testament to this is that there is a second road bridge being built as the first one is basically falling apart.
Conditions weren't that great for taking pictures (22/01/2017), it was cold and misty. I got a couple of shots that I was happy with (click for larger versions).
