QUEENSFERRY CROSSING
2015 – 2017
The 2.7km Queensferry Crossing, Scotland, is the world’s longest three-tower cable-stayed bridge and also the world’s largest bridge with stays that cross mid-span. In a joint venture with Drace Infraestructuras UK, VSL installed 288 stay cables using its VSL SSI2000e system. The use of crossing cables provides stiffness to the structure, allowing the towers and the deck to be slender and elegant. VSL Friction Dampers were also installed on all the cables to enhance the resistance to fatigue while ensuring ease of maintenance during service life.
