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 isolation of the city. This brand new infrastructure must also be respectful and compatible with the local shipyard industry, which has many high-tech facilities inside the bay, employing nowadays more than 6000 workers. Regarding the possibility of the construction of ships or offshore structures with extraordinary dimensions, the new bridge will have a removable span, with 140 m horizontal clearance and no vertical clearance limitations. This original structure, which is in a very advanced stage of construction, will have a single 150 m long steel span with variable depth (between 3 and 8 m) and a 33,2 m wide orthotropic plate. The structural detail design and construction of the bridge is presenting many challenges in relation to its dynamic behaviour, fatigue control, durability and quality control of the manufacturing processes.
