It is understood that at least 50% of the funding for the project has been come from the EU’s European Fund for Regional Development.
Once operational, the port will be able to handle containers in a separate area from where cruise ships are berthed.
Because of its geographical position between the Europe-Africa and US-Mediterranean trade lanes, Cadiz is styling itself as the gateway to Southern Europe.
Port authority president Rafael Barra said the project would “enhance container traffic and contribute to the environmental recovery of the bay”.
He added: “With this project, we complete the port development plan launched in 2000 to focus on the specialisation of the docks and the reorganisation of traffic.”
