The Forth Bridge, located in Scotland, is a famous cantilever railway bridge that crosses the Firth of Forth. Built in 1890 by engineers Sir John Fowler and Sir Benjamin Baker, it's a symbol of Scotland and a UNESCO World Heritage Site. The bridge spans 8,094 feet, with a height of 361 feet above high water. It was once the longest single cantilever bridge span in the world and continues to be the second-longest. Owned by Network Rail, the Forth Bridge is a must-see marvel for anyone visiting the area.
