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 stucture passed engineering  requirements by 400 percent, enabling it to withstand the weight of 71  fully loaded Boeing 747 airplanes (more that 71 million pounds). The  bridge will be able to sustain winds in excess of 100 miles per hour  from 8 different directions, as well as an 8.0 magnitude earthquake  within 50 miles. More than one million pounds of steel will go into the  construction of the Grand Canyon sky walk..................
