The goal of the design was to preserve the form and dimensions of the historic suspended chord beams for the motorway bridge but, on account of the increased span, to add inclined supports, thus forming a frame system. An additional aim was to allow pedestrians to experience the bridge. For this reason, the pedestrian areas were developed by reversing the suspended chord beams into an arch from which a light steel walkway is hung. The inner side of this walkway is supported by the beams of the motorway bridge The bridge thus results from the reversal of two complementary structural systems.
