Birth, development and future of the extradosed bridge

The extradosed bridge ideas dates back to 1988, when Mathivat presented the concept. Since then, this structural type has been used worldwide. The first extradosed bridge was the Odawara Blueway Bridge completed in Japan in 1994. Although the principle was originated in France, it is fair to say that the bridge would not have spread, so far and so quickly around the world, without Japan's efforts to put the principle into practice. In this paper, the progress of the extradosed bridge from its birth to the today state of the art is analysed. Finally some thoughts on the future trends on design of this structural type are presented. (C) 2019 Asociacion Espanola de Ingenieria Estructural (ACHE).
