Bicycle and pedestrian bridge, Sittard-Geleen

The bridge offers a natural and smooth connection to the bike paths from four directions. By basing the design on a reduction of the height of the catenary, the maximum difference in height on accessible surfaces could be reduced to just over three meters. Thus, and because the bridge widens from 4,5 meters in its mid to over 12 meters at the bases, the slopes are bland and comfortable.

The skin of the bridge that is part of the load-bearing structure, and the curved shape of the middle part, enhance the fluent character of the bridge. The parapet also includes safety and guidance. Its skin is perforated as much as possible to achieve transparency. The linear LED lamps that light up the bridgedeck, are integrated in the handrail.

Geometry

The inviting hourglass form and the curved skin, that also extends in height, constitute the basis of an unique and, at the same time, challenging design. The complex form does not have any flat portions and cannot be made with e.g. extrusion-shaped moldings. With the aid of special software, ZJA was able to develop the proper geometry in a relatively simple manner and, thereby generate the necessary templates for an executable production method.
