The Millau Viaduct (Le Viaduc de Millau) is a giant bridge in France that spans over a deep valley. The highest pier is 246 meters. The bridge is present in the default FSX scenery though the pylons unfortunately are missing.
Depart from Larzac, Millau (LFCM) and fly heading 310 or just follow the road beside the airport that will lead you to the bridge.
