Millau Sky Bridge

The Millau Sky Bridge is the world's tallest bridge, a skyway span dwarfing the Eiffel Tower by more than 50 feet. This stunning road bridge has been celebrated as a work of art combining the strength of cement and steel with the "delicacy of a butterfly."

Stretching 1.6 miles through France's Massif Central Mountains, the bridge will enable motorists to take a drive 891 feet above the Tarn River valley.
Designed by British architect Norman Foster, the steel-and-concrete bridge with its streamlined diagonal suspension cables rests on seven pillars -- the tallest measuring 1,122 feet, making it 53 feet higher than the Eiffel Tower.

Colorado's Royal Gorge Bridge, towering 1,053 feet above the Arkansas River, is the world's tallest suspension bridge, and the Kochertal viaduct in Germany was the highest roadway, at 607 feet until the Sky Bridge was constructed to dwarf them all.

The Bridge cost $523 million to build so expect to pay to cross it! But the good news is the old valley road still runs under it giving one of the most spectacular views available for nothing.
