The
Glass Bridge Construction of the Skywalk began in March of 2004 and was
completed by 4th quarter of 2006. Glass Bridge is 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 requir ements 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 has gone into the construction of the Grand Canyon Skywalk.
