Arrábida Bridge - Porto / Portugal

The Arrábida Bridge is an arch bridge over the Douro River that connects Porto (through the Arrábida area) to Vila Nova de Gaia (by the Candal node), in Portugal.
Since the 1930s it was necessary to create alternative connections to the old bridges (bridges D. Maria Pia and D. Luís) in order to respond to the growing flow of road traffic.
At the time of its construction in 1963, the bridge had the largest reinforced concrete arch of any bridge in the world.
The total length of the platform is 614.6m, having a width of 26.5m. Its span of 270 m, and 52 m of shaft, this arch consists of two parallel hollow ribs, 8 m wide, connected to each other by longitudinal and transverse bracing. It had two lanes and two side lanes for pedestrians and cyclists. In the 90's the number of road lanes was changed.
The engineer responsible for his design and construction was Edgar António de Mesquita Cardoso, who had the collaboration of the architect Inácio Peres Fernandes and the engineer José Francisco de Azevedo e Silva
