Where in Europe is the longest bridge

The Vasco da Gama Bridge, named after the great Portuguese navigator of the era of the Great Geographical Discoveries, is located in Lisbon - the capital of Portugal. It is famous for its length of 17 km 200 m, it is the longest bridge in Europe.

Bridge construction


Construction of the colossal bridge took a year and a half, which was preceded by the same period of preparatory work. For such a huge construction period can be considered a record.
The name “Vasco da Gama” was not given over the bridge by chance, since the movement on it opened on April 29, 1998. This was the year when Portugal celebrated a great anniversary - the 500th anniversary of the discovery of a sea route to India from Europe, whose honor belongs to this Portuguese navigator.
The bridge was created in order to take on part of the transport load, which fell on the Bridge on April 25 - a suspension bridge that connects Lisbon with the city of Almada.In addition, it was necessary to connect the highways coming from the Portuguese capital.
Four large construction consortiums worked on the creation of the bridge. 3,300 people took part in the construction.

Characteristic of the bridge


The bridge consists of several sections: the northern access roads, the northern viaduct (488 m), the Expo viaduct (672 m), the main bridge (829 m), the central viaduct (6 351 m), the southern viaduct (3 825 m) and the southern access roads (3 895 m).
The Vasco da Gama Bridge is amazing not only for its size, but also for its beauty. The Tejo River, through which it is laid - the largest river of the Iberian Peninsula, gives a special charm to the bridge.
When designing such a long bridge, we had to take into account the sphericity of the planet. If this were not done, the height of its southern and northern extremities would differ by several tens of centimeters.
The bridge is of tremendous strength. In 1755, Lisbon was destroyed by a terrible earthquake, the magnitude of which modern scientists estimate at 8.7 points, but the Vasco da Gama bridge could withstand a stronger earthquake. The bridge will stand in the event of a hurricane, because it is able to withstand wind speeds of up to 250 km / h.
The creators of the bridge even took into account the impact on the environment. In order to minimize it, the lighting was designed so that at night the light of the lanterns would not fall on the water.
The six-lane road passes along the longest European bridge, and two more lanes are added during peak hours. In good weather, the bridge is allowed to travel at a speed of 120 km / h, and in bad weather - 90 km / h.
