Royal Gorge Bridge
The bridge, as its name gently implies, crosses the Royal Gorge canyon of the Arkansas River near Cañon City, Colorado. It was never meant for transportation purposes but was designed as a tourist attraction for the visitors of the canyon.
From 1929 to 2001 it held the record of the highest bridge in the world, and after it was eliminated from first place in the world, it remained with the title of the highest bridge in the U.S.
