这座人行天桥位于伊丽莎白女王大街，连通克诺克与佛兰德斯。一方面，这座桥将海堤和“低地”的一片绿化区连接了起来，为自行车爱好者和行人提供了旅游观光的可能。另一方面，这座桥象征着克诺克海斯特海洋城的门户。其静态模型是一个长达102米的横梁，下方有4个支柱。因此创造出了一个18米/46米/28米的跨度。

此结构模型起初是人工手绘而成，后来又使用了数字化技术：一种软件系统计算了所需材料量的最小量，从而形成了开口的形状。最终的结果是一个最优化的形状。从概念上讲，这座桥由12毫米厚的钢板焊接而成，形成了一个钢结构“吊床”，上面则是一个混凝土桥面。桥的弯曲形状从而平衡了剪切力，桥面边缘相对中心轴向下偏离的45度之多。

Situated on the Queen Elisabeth Avenue, connecting Knokke with Ostende, this pedestrian bridge full fills two functions. On the one hand, the bridge connects the sea dike with a green zone in the “Polders”, creating tourism possibilities for cyclists and pedestrians. On the other hand the bridge symbolizes the entrance into the marine city of Knokke Heist. The static model is a continuous beam with 102m length that rests on 4 supports. This creates an ideal span division of 28m/46m/28m.

The structural form was first hand sketched, then digitally processed: a software program computed the minimum amount of material required and thus the shapes of the openings. The result is an optimized shape. From a conceptual point of view, the bridge consists of welded bent steel plates of 12mm thickness, forming a structural steel “hammock” to which a concrete deck is tied. To resist shear forces, caused by the bent shape in plan, the sides of the plates are inclined at 45°, with respect to the central axis.
