These photos were taken during tbe construction of the Forth Road Bridge for engineering firm Sir William Arrol & Co which produced and installed the steelwork for the bridge. They were retained by a member of staff who cleared out the offices when the firm went bust in the 1980s
The main cable anchorages, planted into the ground on both shores, as well as the two main towers, were completed in 1961
Nearly 40,000 tonnes of steel and 125,000 cubic metres of concrete went into the bridge’s overall construction
Workers braved the cold and extremely windy conditions, day and night, to build the bridge. Pictured is a temporary cabin put in for workers
That's not all they braved.
These men are helping to fix the steel suspension cables into position, 500ft above the Firth of Forth.
By August 1962, 30,000 miles of steel wires had been spun together to make up the main cables.
Spinning several wires of the main cables back and forth across a river was unheard of in Europe at the time.
At the time, it was the first bridge of its kind in the UK, the longest outside the USA, and the fourth longest in the world.
