A filligree bridge integrates itself in its natural environment
The structure is intended to be elegant and extremely lightweight – as if “above the clouds” – blending harmoniously into its immediate surroundings to the point of becoming almost invisible. The architectural language reflects a subtle and refined interpretation of the site, while simultaneously giving the bridge a sense of robustness. The structural concept allows for an exceptionally slender form at the center, making the bridge appear nearly transparent from both the edge of the gorge and the lower promenade.
From an engineering perspective, the bridge is based on an isostatic system in which two structural systems are superimposed into a unified whole. Each half of the bridge consists of rigid box girders acting as simply supported beams that transfer their loads to the abutments and the central, free-standing V-shaped pier. This central support is stabilized by a tension tie and, together with the compressive forces in the box girders, creates an overall beam action within the structural system. The shape of the box girders follows a parabolic bending moment diagram without support moments. Their high geometric stiffness enables the bridge to carry even asymmetrical live loads with minimal deformation.
The jury’s conclusion:
“The project demonstrates a careful approach to the existing natural and landscape values and stands out for its high-quality design. The filigree, organically shaped bridge girder not only integrates harmoniously into its surroundings but also merges convincingly with its structural function. The railing offers a clearly legible line for users without feeling restrictive.”
