> Facts and Figures About Milhau Viaduct > A Bridge Over the Baltic Sea > Controversial Project in Sicily dimarts, 21 de desembre de 2004
On December the 14th, the Occitan village of Milhau grabbed the attention of much of the media, thanks to the official opening of the highest bridge in the world, built in only three years.
The viaduct over the river Tarn, within touching distance of this village, located in the Languedoc region, is supported by seven pillars, the main one of which stands 343 metres high, some twenty metres higher than the famous and symbolic Eiffel Tower in Paris. The bridge project, designed by the British architect Norman Foster and managed by the French engineer Michel Virlogeux, is of enormous dimensions but with an appearance both elegant and delicate. Beyond the aesthetic appearance, the nearly 2.5 kilometre long Milhau viaduct, now part of the A-75 motorway, shortens the distance between Paris and the Mediterranean and allows the traffic in the area to flow more freely. (With the opening of the bridge, the distance between Perpignan and the French capital is reduced by about sixty kilometres). We should also say that the viaduct has cost 400 million euros and was built by the Eiffage company, who will have the right to collect the bridge tolls for 75 years.
Facts and Figures About Milhau ViaductThe world's tallest bridge is made of concrete and steel, is 32 metres wide and 4.2 deep. The platform reaches a height of 270 metres and has a gentle gradient of a little over 3%. The whole thing weighs more than 300,000 tons, and has been designed to resist gusts of wind of up to 250 kilometres per hour. It is estimated that an average of 10,000 vehicles per day will cross on its four lanes. This figure could reach 25,000 in the height of the summer.
A Bridge Over the Baltic SeaIn July 2000, the bridge linking Denmark with Sweden was opened. In fact, the colossal infrastructure includes a tunnel, an artificial island and a bridge over the Baltic Sea, at the Oresund Strait. The whole thing made it possible to link Copenhagen, the capital of Denmark, in the east of the country, with the city of Malmö, in the south of Sweden. With this 16 kilometre-long connection, the lands on either side of the Baltic became united again, thousands of years after being separated as a result of the end of the ice age.
Controversial Project in SicilyIn contrast to the construction of the Milhau viaduct, the project to unite the island of Sicily, the largest in the Mediterranean, with the Italian peninsula by a bridge over the Strait of Messina, which separates them, has met with fierce opposition. It is the object of criticism from ecology groups and a sector of the Sicilian population, who believe that the island has other priorities; nevertheless, it is planned that construction will begin at the end of 2005 and will conclude in 2011. The bridge will cost about 4,600 million euros and will be some 3.6 kilometres long.
