Forth Bridges

For those that dont know the 2 current bridges crossing the Forth as seen from the south.

The Forth Bridge is a cantilever railway bridge over the Firth of Forth in the east of Scotland, to the east of the Forth Road Bridge, and 14 kilometres (9 mi) west of central Edinburgh. It was opened on 4 March 1890, and spans a total length of 2,528.7 metres (8,296 ft). It is often called the Forth Rail Bridge or Forth Railway Bridge to distinguish it from the Forth Road Bridge, although it has been called the "Forth Bridge" since its construction, and was for over seventy years the sole claimant to this name.

The bridge connects Scotland's capital city, Edinburgh, with Fife, leaving the Lothians at Dalmeny and arriving in Fife at North Queensferry; it acts as a major artery connecting the north-east and south-east of the country. Described by the Collins Encyclopaedia of Scotland as "the one immediately and internationally recognised Scottish landmark",[1] it is a Category A listed building[2][3] and was nominated by the British government in May 2011 for addition to the UNESCO World Heritage Sites in Scotland.[4]

The bridge was begun in 1883, took 7 years to complete, cost the lives of 98 [5] men and nearly 58,000 tonnes (130,000,000 lb) of metal [6] and used 10 times as much steel as the Eiffel Tower. It was deliberately chosen to look strong, due to the collapse 4 years earlier of the first Tay Bridge.[7]

Until 1917, when the Quebec Bridge was completed, the Forth Bridge had the longest single cantilever bridge span in the world. It still has the world's second-longest single span.[8][9] The bridge and its associated railway infrastructure is owned by Network Rail Infrastructure Limited.

And on the left .......
The Forth Road Bridge is a suspension bridge in east central Scotland. The bridge, opened in 1964, spans the Firth of Forth, connecting the capital city Edinburgh, at South Queensferry, to Fife, at North Queensferry. It replaced a centuries-old ferry service to carry vehicular traffic, cyclists, and pedestrians across the Forth; rail crossings are made by the adjacent and historic Forth Bridge.
