Olivia Tan I studied the Millau Viaduct. The Millau Viaduct was opened in 2004 and is located near Millau, France. Millau is a commune located in Southern France at the junction of the Tarn and Dourbie rivers. The purpose of this bridge was to complete the A75 autoroute (highway) in France and to cross the Tarn River. Prior to being built, traffic had to descend down to the river, which caused a lot of traffic. This bridge connects two plateaus and creates a high-speed route from Paris through Clermont-Ferrand and eventually to Barcelona. The Millau Viaduct is a cable stayed road bridge, which is a bridge with one or more columns that have cables supporting the deck. This bridge is a fan style cable stayed bridge where all of the cables are connected at the top of the columns. Constructions lasted from October 2001 until December 2004 and cost €400 million. The bridge uses 127,00 meters cubed of concrete, 19,000 metric tons of steel and 5,00 metric tons of pre-pressed steel for the cables. The construction team faced trouble crossing the river and spanning the huge gap from one plateau to another. To fix these problems, they used seven pillars instead of two or three. The length of the bridge is 2.4 kilometers, the clearance above the river is 270 meters, each section of the bridge is 342 meters long, and the pylons range in height from 75 meters to 235 meters and the bridge is 343 meters tall. The Millau Viaduct is the tallest man made bridge in the world, has the tallest pylons in the world, and is 19 meters taller than the Eiffel Tower media type="googlemap" key="http://maps.google.com/maps?f=q&source=embed&hl=en&geocode=&q=millau+bridge&sll=41.921188,-87.636907&sspn=0.011,0.015471&ie=UTF8&hq=bridge&hnear=Millau,+France&ll=44.422011,3.15033&spn=0,358.019714&t=h&z=9&iwloc=A&layer=c&cbll=44.077006,3.023023&panoid=B361ky55M2OoBB8nDRb0lQ&cbp=12,352.54,,0,19.73&cid=12370756247981880768&output=svembed" width="425" height="350"media type="youtube" key="FzoI6L1XXOk" height="385" width="480"
