The United States, the Grand Canyon of the Colorado scenery is magnificent, but visitors can hardly walk to the edge of the canyon overlooking the valley from the top of the valley, the canyon landscape panoramic view. In order to allow tourists to see the panoramic view of the Colorado Grand Canyon, some people have tried to build a bridge in the narrow gorge. However, after measurements, it was found that the wind speed above the Grand Canyon was so powerful that it reached 160 kilometers an hour. Any bridge could not resist this strong wind and even the bridge could be completed, it would be as awkward as the noodles. As a result, the dream of bridge viewing shattered. This can not be achieved, renewable a plan. A group of skilled engineers are right
