Inauguration of the Zandhazenbrug 26/08/2016: another recordbreaking project!
The Zandhazenbrug is the first railway bridge to be built in S460. Moreover, it is the longest railway bridge in the Netherlands, with a main span of over 250 m. At the same time, from a landscape perspective, a flashy bridge was undesirable. Rijkswaterstaat wanted a slender, airy-looking bridge, whose color and design would not draw too much attention.
Because of the great length in combination with the required slenderness of the main girders and arches, these are made of thermo-mechanically rolled steel S460/ML. This allowed the weight of the bridge to be limited and made it possible to transport the bridge over the highway. The application of S460 ultimately results in a weight saving of almost 30%. The bridge has a steel structure. The two box-shaped arches just barely touch at the top, creating an airy image.
In the design by ZJA and Iv-Infra the architectural design is geared to the constructive characteristics and possibilities for assembly. In the architectural design, ZJA made a visible distinction between the two main components of the bridge: the arch versus the deck. The arches determine the image from afar, the deck is subordinate to them. The project was carried out by the general contractor SAAone , with Victor Buyck Steel Construction responsible for the production and assembly of the more than 8,500 tonnes of steel.
