With a free span of 1 145 m the bridge will be one of the longest suspension bridges in Europe when it opens for traffic in the summer of 2018.
With a total length of 1 533 m and an 18 m wide road, this superbridge will need a considerable amount of special asphalt. The paving of the bridge, which starts this spring, will be performed in two separate contracts. One for the two viaducts with a total length of 400 m, which have a concrete surface, and another contract for the road on the suspension span, which is made of steel.
“Here we required two very different recipes and performance methods,” says Erik Sundet from the consultancy company Cowi. “For the concrete surface we need two layers of PMB A34 (80 mm), while the steel surface requires the use of a water-resistant membrane (80 mm).”
