Queen Elizabeth II Bridge

‘In 1991 the Queen Elizabeth II Bridge was Europe’s largest cable-stayed bridge, carrying southbound traffic across the River Thames from Thurrock in Essex to Dartford in Kent.

By utilising the existing twin tunnels exclusively for northbound traffic, the Queen Elizabeth II Bridge doubled the capacity of the Dartford-Thurrock Crossing. With a minimum air draught of 57.5m above high water, the four-lane bridge comprises a 450 main span, triple side spans of 181m plus viaducts exceeding 1km – reaching an overall length of 2.8km. The cable-stayed deck is formed from stiffened steel plate acting compositely with a structural concrete overlay, supported longitudinally by steel plate girders. The concrete river pier foundations have been designed to absorb impact from a 65,000 dead weight tonnage vessel travelling at 10 knots.’
