The Juan Bravo overpass over the Paseo de la Castellana thoroughfare in Madrid was the winning tender proposal in response to a call for tender issued by Madrid’s City Council. Its composite structure was a total innovation in Spain. Prestressing the concrete deck slab prior to its connection to the steel box girders was a world innovation.
The design makes use of two materials which had never been used before in Spain: white high-strength concrete and Corten structural steel with its increased resistance to atmospheric corrosion.
The highly industrialized construction process used many prefabricated elements so to avoid causing disturbance to the neighborhood.
The innovative formal arrangement combined the structural essence with a formalization of classical roots in a quest for an inherent beauty with a lot of overtones.
