Construction of the Forth Road Bridge first began in 1958, with work carried out by three of Britain's largest engineering firms.
Nearly 40,000 tonnes of steel and 125,000 cubic metres of concrete went into the bridge's construction - though none of this is quite as impressive as the workers, who put their all into the one-and-a-half mile long structure.
It took a workforce of 400 people over three years to complete the bridge - seven of whom lost their lives.
