Abstract
Windbreak barrier for a suspension bridge comprising a substantially rigid flat structure, the top surface of which forms the roadway for the vehicles crossing the bridge, and a suspension system formed of catenary cables and of a plurality of vertical stays or hangers (P) to which is anchored the structure. The windbreak barrier comprises, on the one hand, aerodynamic elements consisting of a pair of horizontal wing surfaces (8, 9) having a symmetrical profile and forming part of a framework, and on the other hand, a vertical grille wall (910) having a transparency of the order of 70% and being mounted on the framework. The wing surfaces have a wing chord of 100 to 150 cm and a thickness, in correspondence of the highest point, of 20 to 30 cm.
