The Grand Canyon Skywalk

1
The Grand Canyon Skywalk The glass bridge which
is suspended 4,000 feet above the Colorado
River on the very edge of the Grand Canyon. The
construction began in March of 2004. 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 than 71
million pounds.) The bridge is 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.
