New Removable Bridge over the Bay of Cadiz

摘要

The construction of the new Bridge over the Bay of Cadiz is necessary to break the secular isolationrnof the city. This brand new infrastructure must also be respectful and compatible with the localrnshipyard industry, which has many high-tech facilities inside the bay, employing nowadays morernthan 6000 workers. Regarding the possibility of the construction of ships or offshore structures withrnextraordinary dimensions, the new bridge will have a removable span, with 140 m horizontalrnclearance and no vertical clearance limitations. This original structure, which is in a very advancedrnstage of construction, will have a single 150 m long steel span with variable depth (between 3 and 8rnm) and a 33,2 m wide orthotropic plate. The structural detail design and construction of the bridgernis presenting many challenges in relation to its dynamic behaviour, fatigue control, durability andrnquality control of the manufacturing processes.
