The Queensferry Crossing’s centre tower is officially the largest freestanding balanced cantilever in the world, according to Guinness World Records.
At 644m long, the free-standing deck is about to be connected to flanking towers and viaducts.
Construction of the bridge has been dogged by difficult weather conditions, leading to a five-month delay in completion. The Forth Crossing Bridge Constructors (FCBC) joint venture of Hochtief, Dragados, American Bridge International and Morrison Construction said it will now open in May 2017.
“Construction work is going well on all three towers. This unique achievement at the centre tower is a feat of engineering which the whole FCBC team is immensely proud of. This is leading edge civil engineering and I’m delighted to pay tribute to the skills and dedication of everyone involved,” said FCBC construction director Alan Platt.
Scotland’s cabinet secretary for the economy Keith Brown added: “We can all agree the Queensferry Crossing is a modern marvel and a world-class feat of engineering. It’s only fitting then that the bridge has been awarded a Guinness World Records title.
“This world-record breaking structure is all the more remarkable when you consider the extreme weather conditions often experienced out in the Firth of Forth, especially working up above the water between 60m and 210m high. Everyone who has worked so hard and skilfully to build this amazing bridge is a world record beater in their own right.
“It won’t be long before the balanced cantilever disappears, when the small gaps between the towers are closed. But the record is still there to be beaten and the Queensferry Crossing will still be the tallest bridge in the UK and longest bridge of its type anywhere in the world.”
