The Millau Viaduct is the world’s highest road bridge, peaking at a height of 1,125 ft (343 m) and stretching across 8,071 ft (2,460 m).

After more than a decade of planning and construction, the bridge was inaugurated by French president Jacques Chirac in 2004. How much did it cost to build? Discuss
