Technical heritage of Madrid's bridges

Resumen

Madrid's bridges trace a path through the evolution of construction technologies over the past five centuries. Since Madrid became capital of Spain in the 16th century, bridges have taken centre stage in the growth of the city. Firstly, they crossed its rivers; later, they crossed other obstacles and connecting routes. Over time, they display a succession of materials, types, and technological solutions. They include unique works and key historical figures in the history of construction. We propose a chronological analysis of materials and techniques; masonry bridges, iron bridges, reinforced concrete, pre-stressed concrete, composite bridges, and modern designs. Studying them from a technological point of view offers a previously unseen view of their major significance in our heritage. The individual value of each one is added to with overall historical and cultural value. This article helps to highlight the individual and collective relevance of Madrid's bridges, and it is also a chance to take a look back over the technical development of bridge engineering up to the present day.
