Rising above the Tarn River valley, the Millau Viaduct represents an engineering triumph and a modern French landmark. At 1,125 feet above ground, it's the world's tallest bridge, with elegant pylons reaching skyward.

Suspended above the earth with only a narrow road beneath and boundless sky surrounding is both thrilling and daunting.
