The Glass Bridge Construction of the Skywalk began March of 2004 and is estimated to be completed by 4th quarter of 2006. Glass Bridge will be suspended 4,000 feet above the Colorado River on the very edge of the Grand Canyon. On May 2005, the final test was conducted and the structure passed engineering requirements by 400 percent, enabling it to withstand the weight of 71 fully loaded Boeing 747 airplanes (more that 71 million pounds).
