Bridges+Presentations

Vasco da Gama Bridge is 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. Transforming this public dump into a quality area, decontaminating 330 hectares of land and cleaning up 5 kilometers of river front took four years .



Vasco da Gama Bridge crosses the Tagus River (Rio Tejo) about 20 km upstream from the 25th April Bridge, located in the heart of Lisbon. It opened a second north-south corridor and is part of a new road corridor to Spain

Why a second bridge over the Tagus River: need for an alternative north-south traffic link to bypass Lisbon and reduce traffic congestion in the capital.
