The design is characterized by its streamlined simplicity and clear visual language, according to the principles of the 'Ligne Claire", a style that has its origins in the Belgium of Tintin creator Hergé. The two freestanding arches literally form the climax of the bridge and are clearly visible to the millions of travellers who pass the Brussels ring road every year in a southward direction. A subtle choice is the configuration of the hangers under both arches. They have a common virtual vanishing point 80 metres above the middle of the bridge. This geometric principle ensures that the hangers never cross each other optically. An additional consequence of this configuration is that the optimal pressure line of the arch is influenced by it; the arch becomes more tapered than the more common parabolic arches which have vertical cables. The arcs become more slender upwards as the pressure in the arc decreases. The birth of the arches, on the other hand, is broadly set to provide lateral stability to compensate for the absence of cross-links between the arches.
