The Millau Viaduct is an enormous cable-stayed road-bridge that spans the valley of the river Tarn near Millau in southern France. It is the tallest vehicular bridge in the world, with the highest pylon’s summit at 343 meters (1,125 ft) — slightly taller than the Eiffel Tower. The speed limit on the bridge was reduced from 130 km/h (81 mph) to 110 km/h (68 mph) because of traffic slowing down, due to tourists taking pictures of the bridge from the vehicles. Shortly after the bridge opened to traffic, passengers were stopping to admire the landscape and the bridge itself.
