Technical heritage of Madrid’s bridges, Spain

Abstract

Madrid’s bridges trace a path through the evolution of construction technologies over the past five centuries. Since Madrid became the capital of Spain in the sixteenth 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. The authors propose a chronological analysis of materials and techniques: masonry bridges, iron bridges, reinforced concrete, prestressed concrete, composite bridges and modern designs. Studying them from a technological point of view offers a previously unseen view of their major significance in heritage. The individual value of each one is added to the overall historical and cultural value. This paper helps 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.
