The Forth Bridge is the famous Scottish railway bridge completed in 1890 with three cantilever spans.
It crosses the Firth of Forth between South Queensferry and North Queensferry. The bridge was designed by John Fowler and Benjamin Baker and opened on 4 March 1890. Its three main spans each measure 521.3 metres, making it a landmark of nineteenth-century engineering.
The structure was built from more than 50,000 tonnes of steel and millions of rivets. Its distinctive red paint and massive cantilever arms made it one of the best-known railway bridges in the world.
The Forth Bridge is separate from the nearby Forth Road Bridge and Queensferry Crossing, which carry road traffic. UNESCO added the railway bridge to its World Heritage List in 2015, recognising its engineering importance and dramatic setting.
