The access to the city of Cadiz from the Carranza Bridge or from the southbound motorway made it necessary to drive right through the city along the Andalusia Avenue in order to reach the Port and the Old Town.
Road traffic along this thoroughfare became easily congested even when passage over the José León Carranza Bridge, often jammed by heavy traffic as well, was possible. This is why the authorities of the Spanish Ministry of Public Works and Transport decided to fulfil the old aspiration of the city to build a new access that would reach Cadiz directly from Puerto Real, ending up on the other side of the city on the Bahía Avenue right by the Port and the Old Town.
