Royal Gorge Bridge, Colorado

This suspension bridge, over the deep Royal Gorge in the Arkansas River, is one of the highest bridges in the nation, at 956 feet above the water level, and was constructed in six months in 1929. Today, the bridge is somewhat overwhelmed by the tourism industry surrounding it. Several western theme towns, gift shops and other attractions line the road to the gorge, and the bridge itself has tourist complexes on either end, with restaurants, rides, an aerial tramway, and more shops.
