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.
