Places - The longest bridge in Europe


The Vasco da Gama Bridge

The Vasco da Gama Bridge is a cable-stayed bridge that spans the Tagus River near Lisbon, capital of Portugal.

The bridge was opened to traffic on 29 March 1998 and it is the longest bridge in Europe, with a total length of 17.2 km.

Due to the bridge's length, it was necessary to take the Earth's curvature into account to site the piers correctly, otherwise a deviation of 80 cm (31 in) would be apparent at either end of the bridge.

The bridge has a life expectancy of 120 years, having been designed to withstand wind speeds of 250 km/h (155 mph) and hold up to an earthquake 4.5 times stronger than the historical 1755 Lisbon earthquake (estimated at 8.7 on the Richter scale).

The deepest foundation piles, up to 2.2 m (7.2 ft) in diameter, were driven down to 95 m (312 ft) under mean sea level.

The marker on this map shows the plane's position.
