2. Millau Viaduct Bridge, France

Rising 1,125 feet above the Tarn River valley, the Millau Viaduct Bridge is among the most audacious technical triumphs in contemporary bridge building. Designed by structural engineer Michel Virlogeux and architect Norman Foster, this architectural wonder is the tallest bridge in the world—with its highest point rising to a startling 1,125 feet (343 meters) above the valley floor. For people with acrophobia, or fear of heights, the bridge's amazing height and graceful architecture make it both breathtaking and maybe intimidating.
Despite its great size, the seven thin piers and cable-stayed construction of the tower give an amazing lightness. Seeming to float above the clouds on hazy days, the bridge spans a total length of 8,071 feet (2,460 meters), adding to both its beauty and terrifying aspect. Crossing this engineering wonder can be extremely intimidating for those who have a phobia of heights, particularly if view is clear enough to observe the great drop to the valley below.
The building of the bridge was an amazing accomplishment using creative materials and techniques. Its sleek look and harmony with the surroundings depend on its steel rather than more conventional concrete deck composition. Although some would find the height difficult, the bridge's strong safety measures and stable construction guarantee a safe crossing for all kinds of vehicles, hence it is a necessary component of the A75 autoroute from Paris to Barcelona.
