The Forth Bridge spans the Firth of Forth between South Queensferry, near Edinburgh, and North Queensferry in Fife. Opened in 1890, it remains an active railway crossing rather than a preserved structure closed to transport. Historic Environment Scotland says it carries more than 200 trains a day; the exact service pattern belongs to the current railway timetable. Its red steel profile is one of Scotland’s most recognizable industrial landmarks.
The bridge is about 2.5 kilometres long and rises roughly 110 metres above its granite piers. UNESCO describes it as the world’s earliest great multispan cantilever bridge and notes that its 521-metre spans held a world record for 28 years. The scale is easier to appreciate from shore than from a train: from the carriage, passengers cross the engineering work in minutes, while the broad structure reads as a sequence of towers, arms and suspended spans from a viewpoint.
