The Millau Viaduct is one cable-stayed road bridge that aims to impress. It’s the 12th highest bridge in the world and the world’s number one tallest bridge with a single mast height of 343m (1,125 feet) – that’s taller than the Eiffel tower! British architect, Norman Foster and French structural engineer, Michael Virlogeux worked together to design this autoroute that stretches from Paris to Montpellier, and ended up costing a pretty penny (or €400 million worth of pennies). The bridge took a mere three years to complete and spans the valley of the river Tarn near Millau in Southern France and was given the 2006 IABSE Outstanding Structure Award. The bridge was born out of traffic necessity – during rush hour and holidays, the route from Paris to Spain was so busy that something needed to be done to alleviate the line-up of angry drivers. Now, drivers (who aren’t afraid of heights) can opt for a faster route that offers some pretty spectacular views high up in the clouds.
