The Millau Viaduct is almost 2.5km long and crosses the valley of the River Tarn in south Central France. France’s A75 passes over the bridge and serves as an important route from Paris to Spain. The world’s tallest pylon can be found supporting this bridge, rising a whopping 245m over the valley below. This will not be the record holder for long, however, as the Baluarte Bridge in Mexico, scheduled for completion in 2012, will reach a height of 390m.
