Europe's longest bridge

Vasco of Gama Bridge the longest of Europe photographed from one of the pontoons of the Tagus River Walk in the Park of Nations in Lisbon Portugal and still today one of the longest in the world. 
(It has the same length as the road-rail tunnel-bridge linking Denmark and Sweden).
 Its vastness forced engineers to factor in the curvature of the Earth during its construction. That makes it a superb feat of engineering, made up of several sections supported by pillars, built at a cost of one billion US dollars.
  It was inaugurated on March 31, 1998 after only 18 months of construction, and just in time to carry visitors from southern Portugal, Spain, and other parts of Europe to Expo98.

Vasco da Gama Bridge (Ponte Vasco da Gamma) is the longest bridge in Europe, crossing the Tagus River from Parque do Tejo in Lisbon on the north side of the Tagus to Montijo on the southern side. The bridge is 17km long, 10km of which is over the water. It was built as an alternative route over the Tagus to Ponte 25 de Avril.






Ponte Vasco da Gamma took 18 months to build, opening in 1988 in time for the Expo 98 World's Fair that celebrated the 500th anniversary of the discovery by Vasco da Gama of the sea route from Europe to India. The bridge has a life expectancy of 120 years, and is designed to withstand earthquakes and 250 km/h (155 mph) winds. The entire costs are covered by tolls.

On completion, Vasco da Gama Bridge was considered one of the largest and most successful civil engineering projects of the 20th century and was awarded the 1st prize by the prestigious institution Ibero-American Architecture and Civil Engineering in 2000.

This picture shows a view from the banks of the Tagus River next to Parque do Tejo just south of Vasco da Gama bridge. Within this pleasant park is a statue to Catarina de Bragança who played a pivotal role introducing tea to England. Further along the shoreline you can see the Park of Nations and the Torre Vasco Gama (Vasco Gama Tower), a very popular tourist attraction with a panoramic viewing platform at the top.
