The new pedestrian and cycling bridge supposed to link the streets Ayala and Marqués de Zafra in Madrid, over the underpass in Manuel Becerra square, was recently inaugurated. FHECOR Ingenieros Consultores designed this footbridge and drafted the Construction Project for the Madrid City Council. The construction works, which lasted four months, have been carried out during both day and night shifts, in order to minimize interferences with road and pedestrian traffic. The structure is composed of steelwork elements and spans 16,60 m with a clear width of 6,00 m, where pedestrian and cycling flows are segregated. The main structure is geometrically simple and consists of two T-shaped full stem built-up beams. There have been also designed a set of steel slats in the external soffit of the main beams. These slats, with variable geometry along the length of the beams, suggest the shape of an “M”. Secondary structure consists of steel joists between the two main beams connected to a composite slab. This connection allows reducing the dropped depth of the structure, strictly limited by the clear height of the underpass, thanks to the composite behavior of these elements.
