Keynotes on bridges in Spain since the mid-1980's

Spanish bridge engineering has developed creative and efficient answers to the challenges set by the extraordinary development of road and railway infrastructure during the last 25 years. This process provides continuity to the great tradition of good bridge engineering practice based on the ambition of overcoming such engineering challenges. These efforts also resulted in the exploration of new fields: typology, by generating new ideas to improve structural behavior; construction methods, by using new technologies (many of them perfected for other fields of activity) and by innovations using new specific methods for particular cases; structural materials by exploring the benefits of their new possibilities, deepening in the use of traditional composite steel-concrete structures and starting a very interesting process of using composite materials.

Consistent with the old aphorism “learning by doing” the lessons learnt from these daring tasks and experiences will remain in the back of these engineers' minds which will ensure continuity for future developments. At the present and in the near future, Spanish bridge engineering must face new challenges in design and construction in foreign countries, taking advantage of the experience gained during the past 25 years.
