Descriptif

La Paix footbridge is at the centre a soft mobility urban connection linking place des Nations to Perle-du-Lac park. It transits by Maison de la Paix, overslung from its base on the north side. Designed in two large sections, of slightly different dimensions, the bridge passes over the railway line with an intermediary support at the level of the RER train station, which breaks the span. The structure’s two abutments and double central pillar are in concrete whereas the four horizontal truss beams are metal. The general design of the bridge seeks to give a sculptural effect: a slanting form whose bends join diagonally two inflection points, which are the entrance to the train station in the centre and the staircase of the Sécheron park and ride facilities to the south. This design makes the walk over the footbridge differ greatly according to where you are, the two sides never having the same height. The view over the trains is partly hidden so that the eyes are caught by a unique longitudinal view opening up to the south of the town. The inner part of the bridge is covered with transparent glass panels that are illuminated at night with effects that play on the concept of transparency or perforation from which the structural design emerges evanescently.
