Photographer's Note

This is Central Viaduct Vasco da Gama Bridge

Central Viaduct was carried out using double pre-cast units with 78 m long weighing 2,200 tonnes placed on 81 piers. The foundation of each pair of piers are cast on 8 driven piles, with 1, 7 m diameter reaching sometimes 65 m deep on the river bed.
The deck is less than 14m above water level for most of its length but rises to 30 m over two navigation channels, the Barcas Channel and the Samora Channel with spans of 130 m to accommodate medium sized vessels.
The piers located on these two channels were also designed to withstand ship impact.
This central span is of 420 m and the side spans of 203 m.
