Notes
The main cable-stayed bridge is a prestressed concrete structure with a double plane of stay cables and conceived as an integral framed structure between the expansion joints. Piers, towers, deck main girders and stay cables lay in two parallel planes. Piers and towers are box concrete sections; main girders of deck are solid section. All construction is concreted in situ.
The approach viaducts have double columns piers while the deck is made of parallel simply supported precast girders with 40-meter spans.
