The solution of a multiple-span viaduct cable-stayed bridge, presented by the structural engineering group "Sogelerg", "Europe Etudes Gecti" and "Serf", and the architects "Foster + Partners" was declared the best. Detailed studies were carried out by the successful consortium, steered by the highways authority until
