The discovery of the unique structures Grand Canyon Sky Walk
Opening of the unique structure Grand Canyon Sky Walk held on March 20, 2007.
This is the world's first cantilevered glass bridge in the shape of a horseshoe, which hovers over the Grand Canyon at an altitude of more than 1 kilometer from the bottom of the gorge and at a distance of 21 meters from the edge of the abyss.
A person can enjoy a 720-degree review, nothing prevents.
Transparent floor of the bridge width of 10 cm and all of its open glass structure make it possible to "take a step off the edge of the Grand Canyon," a look at this amazing wonder of nature with a bird's-eye view and under the feet of height twice as large as the tallest skyscraper ... However, "GLASS "Bridge is misleading: it was used in the construction of more than 450 tons of structural steel. It can simultaneously be 120 tourists, but the authors of the project say that this number does not show the true "capacity", the strength and reliability of the Skywalk. According to them, the bridge can withstand the weight of 36,500 tons, and an earthquake of about 8 points at a distance of 80 km and the wind at a speed of 160 km / h
Skywalk bridge width is 3m in length - 42 m, height of walls - 1.5 m Today the Grand Canyon SkyWalk - the tallest building in the world and the world's first such facility, and reinforcing bars that hold the bridge - the largest in the world. Interestingly, the construction of this engineering marvel not used cranes.
