The Millau Viaduct was built over one of the deepest, widest, and windiest canyons in the world. The two ginormous bridge deck pieces were slid together and assembled like a giant jigsaw puzzle.The Millau Viaduct, a cable-stayed bridge that spans the Tarn River Valley in southern France, is a bridge that is both tall (in structural height) and high (in deck height). The viaduct's bridge deck soars 270 m (890 ft) above the valley floor, placing the bridge among the twenty highest bridges in the world.
