ROADS & BRIDGES
Cause For Celebration
The Queensferry Crossing Centre Tower deck span, at 644 metres, has been officially recognised as the longest, free-standing, balanced cantilever structure ever built anywhere in the world.
Due to open in May 2017, the world’s longest three-tower, cable stayed bridge is located between Edinburgh and Fife, Scotland. The scale of the structure is truly impressive.
- The structure will be 207 metres above high tide (68 ft) and 50 metres (25%) higher than existing Forth Road Bridge.
- 150,000 tonnes of concrete will be poured
- The steel required for the bridge deck (final design) weighs a total of 35,000 tonnes.
- The combined steel required for North and South viaducts weighs 7,000 tonnes.
- There will be 37,000 kilometres of cabling used.
- It is estimated the construction will involve approximately 10 million man hours.
- Two lanes of motorway and a hard shoulder running both north and south bound.
- Windshielding to almost entirely eliminate the need for closures during the frequent periods of high winds in the Forth estuary – a significant resilience issue experienced with the current Forth Road Bridge which does not have wind shielding.
