The Forth Bridge

The Forth Bridge is a 2.5km-long, 110m-high cantilever bridge, linking Edinburgh and the Lothians to the south with Fife and the Highlands to the north.

Stretching across the estuary of the River Forth, the Forth Bridge was innovative in its design, materials and scale – while it avoids decoration, it achieves tremendous grace for something so solid.

The Forth Bridge was designed by English engineers Sir John Fowler and Sir Benjamin Baker and constructed by William Arrol of Glasgow. The firm was also in the process of rebuilding the Tay Bridge and building the Tower Bridge in London. At the time of its completion in 1890, the Forth Bridge was the longest cantilever bridge span in the world – a title it held for 27 years. It was also the world's first major steel structure and a marvel of scientific application in architecture.  

Today, the Forth Bridge remains a potent symbol of Britain’s industrial, scientific, architectural and transport heritage.

A major rail crossing, the bridge still carries more than 200 trains a day. It was restored during an ambitious refurbishment programme, completed in 2011.

UNESCO inscribed the Forth Bridge as a World Heritage Site on 5 July 2015.

Its Statement of Outstanding Universal Value describes the bridge as a masterpiece of human creative genius and an aesthetic triumph in its achievement of tremendous grace, despite its solid construction and lack of any decoration. The Forth Bridge’s steel-built cantilever design represents a unique level of creative genius, used to conquer a natural barrier of a scale and depth that had never before been overcome by humans. A unique milestone in the evolution of bridge and other steel construction, the Forth Bridge is innovative in its design, concept, materials and enormous scale. Its application of science to architecture went on to profoundly influence mankind in ways beyond bridge-building.

Network Rail owns the Forth Bridge and is responsible for its operation and maintenance, but wider World Heritage issues are coordinated by the Forth Bridges Forum.

The Forum is responsible for implementing actions in the Forth Bridge World Heritage Management Plan. It includes representatives from:

• Transport Scotland

• Network Rail

• Historic Environment Scotland

• VisitScotland

• West Lothian Council, Fife Council and City of Edinburgh Council

• the Forth Bridges Operating Unit Company

The Forth Bridge is located in central Scotland. It crosses the Forth River estuary between North Queensferry in Fife and Queensferry in the Lothians.

There is no access onto the bridge itself other than by train, but the Forth Bridges Trail offers spectacular views on a circular 5 mile route that explores both sides of the Firth of Forth.
