The Forth Bridge in Scotland is a Victorian engineering marvel, opened in 1890 and designated a UNESCO World Heritage Site.

About this subject

The Forth Bridge is a cantilever railway bridge spanning the Firth of Forth in Scotland. Completed in 1890, it was the world's first major steel structure, using over 54,000 tonnes of steel. With a total length of 2,467 metres and a maximum height of 110 metres, the bridge was designed to withstand strong winds and heavy train traffic.

Built over six years by approximately 4,600 workers, the bridge employed innovations such as Portland cement and painting with iron oxide-based paint, giving it the iconic red colour. Contrary to the popular myth that painting the Forth Bridge is a never-ending task, modern paints last longer and maintenance is scheduled.

The Forth Bridge is one of three major crossings over the Firth of Forth, alongside the Forth Road Bridge (1964) and the Queensferry Crossing (2017). In 2015, it was inscribed as a UNESCO World Heritage Site, recognising its exceptional universal value as an engineering feat and industrial aesthetic.

The structure consists of three large cantilever spans, each 521 metres long, supported by four steel towers. Each tower has diamond-shaped legs connected by trusses. The bridge still carries daily passenger and freight trains, linking Edinburgh to Fife and northern Scotland.
