Dr Mike Glover, technical director for the Queensferry Crossing project’s employers delivery team, has said the bridge should last at least 150 years. Here are some facts and figures behind the large-scale project:

1.35:

billion pounds, the approximate cost of the entire project

65: 3:

options were considered for the design

16,869:

cubic metres of concrete poured into the south tower: a world record for the largest continuous underwater concrete pour

150,000:

tonnes of concrete poured throughout the project, nearly the same used in the London Olympic Park and athletes’ village the number of towers on the cable stayed bridge

13.7:

miles, the overall scheme, including major motorway upgrades

122:

deck sections, each weighing up to 750 tonnes

1.7:

the length in miles, or 2.7km, making it the longest three-tower cable stayed bridge in the world

210:

the height of the towers, in metres. The highest in the UK

48:

London buses would be stacked on top of each other to reach the height of the towers

50:

metres higher than the existing Forth Road Bridge

35,000:

tonnes of steel used in the superstructure

23:

Kelpies could be built with the amount of steel in just the north and south viaducts

23,000:

miles of high tensile wire used in 288 stay cables. End to end it could nearly stretch around Earth

35,000: 644:

votes cast to name the bridge metres of the centre tower deck fan which made it the longest free-standing balanced cantilever in the world

18,000,000:

man hours involved
