Millau Viaduct Bridge was founded to alleviate the kilometers-long of traffic congestionin every year that makes traffic jams happened as the tourists make their way in south during the summer, going the valley into a Millautown that became a popular jamming in the A75 auto route. The construction in this place was quite difficult as that region that is known having high winds and for the valley there is deep, causing in the long period of planning and research, investigating some appropriate routes and it takes 10 years in past for the first construction began in this area. This area becomes the highest bridge that has defeated Eiffel tower, this bridge has 2460 meters length and it touches the Tarn valley bottom for around 9 places. Created by French engineer Michael Virlogeux and Lord Norman Foster, Engslish architech, designed it well,this bridge fits into the perfect and luxury landscape naturally; a roadway that has curved and very steel is strongly supported that creates the look of a large ship and contained in 7 pillars that is thin..
The Millau Viaduct Bridge has a beautiful design. This bridge has 2460 meters length and comprises the eight spans: the 2 side spans has 204 meters and the 6 inner spans has 343 meters. The cross section contains of steel box that has the orthotropic deck, two inclined outer plates and two inner webs vertically. The construction for incremental launching requires vertical webs.And then,the triangular boxes in the outside makes a streamlining cross section that alleviates the wind effect on this bridge. The wind shields are installed perfectly on the beam in outside, it prevents the hihg-sided vehicle overturns. The edges there increase the aerodynamic path and its look. Due to its great design of height from the valley above, a girder in the center is the most amazing design to prevent the twin piers with only one cable plane.
The piers in Millau Viaduct area have varying cross-section. The dimensions are selected in a nice way that they can be formed easily. The four sided have constant dimensions, and the others have vary uniformly in each of the construction section. The permits construction is with the outer jumping forms and the inner forms that are stepwise lifted by tower crane. The sliding forms have made the correct installation of the built-in items difficult.
The Millau Viaduct Bridge is an important example for the series of cable stayed bridges. The structure with the impressive elegance was built in such an impressive landscape, where it crosses gracefully the valley in a great height.
