Esta é a "The Grand Canyon Skywalk", ou a passarela aérea do Grand Canyon. trata-se de uma ponte de vidro suspensa à mais de 4000 pés de altura acima do Rio Colorado, no ponto mais alto do Grand Canyon. A construção começou em março de 2004. Em março de 2005 ela passou pelo teste final de sustentação, quando foi levada ao limite de sua capacidade que é de suportar o peso total de 71 Boeings 747 completamente carregados.A ponte foi projetada para resistir a ventos de mais de 120 Km/h, mesmo que eles mudem de direção (foram previstas 8 posições diferentes de vento) e a terremotos de até 8 graus na escala Richter. A obra demandou mais de 1 milhão de toneladas de aço. O efeito é surpreendente. É como se as pessoas caminhassem no vazio. (*)Colaboração da minha querida leitora teacher

Grand Canyon Skywalk
The Grand Canyon Skywalk opened last month — if you missed the worldwide media frenzy you must be living under a rock or in a hole.
The BBC, CNN, the New York Times, LA Times, Las Vegas Review-Journal — all the major media covered the opening ceremonies. And there were VIPs and travel industry types aplenty, from astronaut Buzz Aldrin to Viator’s very own Rod Cuthbert (read Rod’s blog post about the Skywalk opening ceremonies).
Rod had a great time at the event, and he remains an enthusiastic supporter of the Skywalk and its caretakers, the Hualapai tribe. Rod did have some concerns about the inevitable crowds the Skywalk would draw, and the ability of the organizers to cope with the rush of visitors.
Based on feedback we’ve received here at Viator, Rod’s concerns seem justified. Bigger than expected crowds are making their way to the Grand Canyon’s West Rim each day, and they’re finding they need to be well pr
The Grand Canyon Skywalk is a tourist attraction, commissioned by the Hualapai Indian tribe, unveiled March 20, 2007 and to be opened to the public on March 28, 2007, along the Colorado River on the edge of the Grand Canyon in the U.S. state of Arizona. The Skywalk charges $25 per person in addition to Grand Canyon West entry fees.The horseshoe-shaped glass walkway is suspended 4,000 feet (1 219 meters) above the canyon, a height that eclipses the world's largest skyscrapers.It protrudes 65 feet (20 meters) from the edge of the canyon, and its walls and floor are built from glass 4 inches (10.2 cm) thick. The Skywalk is able to hold 7 tons of weight, allowing for 800 people weighing 175 lbs. (80 kg) each to stand on the bridge; the allowed capacity, though, will be limited to only 120 persons. All visitors will be provided with shoe covers to protect them from slipping and to prevent scratching of the glass floor.More related :The Smallest Owl in The World - XenoglauxAn egg unexpected
