It’s located next to the site where Expo '98 stood and today stands Parque das Nações (Park of Nations). It's located on the eastern end of Lisbon which, until the beginning of the nineties, was the poor side of the capital, full of abandoned containers, garbage depots, junkyards, slaughterhouses, arms factories, refineries and gas terminals, in short, a rundown area in dire need of redevelopment. It´s a cable-stayed bridge (the longest in Europe and one of the largest of its kind in the world) made by reinforced concrete structure with main deck stayed to main pylons. The bridge meets the need for an alternative north-south traffic link to bypass Lisbon and reduce traffic congestion in the capital
