The Millau Viaduct is part of the expressway connecting Paris and Barcelona and features the highest bridge piers ever constructed. It is taller than the Eiffel Tower. The Millau Viaduct is not straight, because a straight road could induce a floating sensation as you drive across it. So, a slight curve remedies that feeling. The bridge was entirely privately financed and cost 394 million euros. Designed by the French structural engineer Michel Virlogeux and British architect Norman Foster, it is the tallest bridge in the world with one mast\’s summit at 343.0 meters above the base of the structure. It is also the 12th highest bridge in the world, with a 270 meters drop from the bridge road to the valley below. The 2460 meters long bridge is a stunning architectural and design feat.
