Towering above the Tarn River valley, the Millau Viaduct is a marvel of modern engineering. At 1,125 feet, it’s the tallest bridge globally, with slender pylons piercing the clouds. Its views are breathtaking, but for those afraid of heights, crossing it is daunting. The sensation of gliding high above the landscape, with open sky all around, is both thrilling and nerve-wracking.
