A New York-based bridge expert is the brains behind the new Clyde swing bridge at Renfrew.
Design engineers Hardesty and Hanover – headquartered on Broadway – have been drafted into the £79.5 million project.
They’ve now released more details on the pioneering Renfrew-Yoker link . . . which will sink the Renfrew Ferry service run faithfully for 250 years.
Hardesty and Hanover – known as H&H – and Irish civil engineer Roughan & O’Donovan say it will take three years from now to construct.
The Renfrew bridge will be 603-feet long and 40 feet wide, carrying vehicles, cyclists, and pedestrians.
The pivoting motion will mean the entire bridge can be moved off the water – allowing giant warships built upriver at BAE Systems in Govan to pass through.
Paul Skelton, of H&H, said: “This is a complex kinetic structure and our structural, mechanical, and electrical controls specialists will ensure that the bridge and its machinery function as one.
“This will bring to life an elegant and unique bridge that offers pedestrians and cyclists a less-steep journey across the Clyde while also providing a significant opening for marine traffic.”
The Clyde swing crossing is the centrepiece of the Clyde Waterfront and Renfrew Riverside renewal aimed at transforming the waterfront and connecting riverbank communities.
The architect is Tony Kettle who created the Falkirk Wheel.
The pivoting bases are 426 feet apart and hydraulic switchgear will open and close in a “bob-tail” arrangement.
The pivots are designed to sit on 22-feet diameter bearings and the steel superstructure is supported by cable-stays anchored to steel pylons and a counterweighted back span.
Planning consent has already been obtained and the design and build is being lead by civil engineers GRAHAM, with Hollandia Infra, lemants, Ramboll, Amey, Hycom Engineering, and Fairfield Control Systems all involved.
H&H engineered the new 1.1 mile long Kosciuszko Bridge which carries 160,000 vehicles every day between Brooklyn and Queens.
The bridge is jointly funded by the UK and Scottish governments through the £1.13 billion Glasgow City Region City Deal.
It will support around 700 jobs during construction.
