The C-15 road, also called Eix Diagonal, is a 65 km long new road linking the cities of Vilanova and Manresa, in Spain. This road infrastructure has been Designed and Built according to a Public Private Partnership contract. PEDELTA has collaborated as bridge designer and specialist in 50 bridges, from the conceptual design to the construction engineering.
Most structures are concrete precast beams bridges, but our services have also included the design of a double box composite bridge, the demolition project for two overpasses with post-tensioned concrete slabs, one bridge widenign and the design of two curved post-tensioned U beams.
Design was carried out meeting the Spanish Code requirements. Traffic disruptions were a major concern mostly in the bridges crossing the AP-7 and C-32 highways and the viaduct crossing the High Speed Railway Line. Some bridges were additionally designed for a future lengthening, as the ones located in the N-340 road junction.
