17 April, 2004 Royal Gorge Bridge Canyon City, CO. - Hanging 1,053 feet above ColoradoÕs wild Arkansas River, the Royal Gorge Bridge is the world's highest suspension bridge and a legendary feat of engineering renowned the world over. Built in 1929 for $350,000, the cost today would easily exceed $15 million. But for those who venture across it, whether walking or driving, the experience is priceless. (Photo by Walter G.
