The pedestrian bridge, located over the high speed railway between Madrid and Barcelona, was built in 2001. It is a full GFRP structure using standard pultruded profiles. An important issue was to find an appropriate structural form to span the required 38 m of length using standard GFRP profiles.
The final structure is a double-tied arch of 38 m span-length having a rise of 6.2 m and 3 m wide. The total weight of the bridge is approximately 19 T. It is likely to be the longest span bridge in the world using this type of structure, i.e. the arch with GFRP standard profiles. The pedestrian bridge was awarded with the international Footbridge Award 2005 (category innovation) in Venice.
The range of applications of advanced fibre-composite materials is very wide, particularly when minimum maintenance, lightness, transportation facilities, short erection times, no magnetic interaction or quick erection times are required. Initial cost due to material supply and design is higher when compared with traditional steel-based solutions, however, considerable savings are made in construction and maintenance.
