Structural Concrete Issue 04/2014
Cover Story: One of Netherland’s most important north to south corridors is the A50 motorway and a part of it the Waal Bridge near Ewijk with a main span of 270 m. Build between 1971 and 1976, it is one of the longest bridge structures in the Netherlands.
The Rijkswaterstaat, the executive arm of the Dutch Ministry of Infrastructure and the Environment, has decided to widen the A50 motorway between Ewijk and Valburg in both directions from two to four lanes each over a distance of 7 km. The entire project was carried out within the scope of a Design-Build contract. The consortium responsible for its execution and design is Waalkoppel, a consortium consisting of Mobilis, Van Gelder B.V. and DYWIDAG Bau GmbH. (see page A5 f)
