Skywalk - Look down 4000 feet below your feet

I couldn’t decide if I should have put this piece in Online Humor or Unusual Technology. Unusual won because while the picture is amusing, the thought of walking 70 feet into the Grand Canyon and 4000 feet above the Colorado River on a see through floor is a bit unusual.

The bridge is built with more than a million pounds of steel beams with a glass bottom and sides and is designed to hold up to 72 million pounds. In addition the bridge is said to withstand an 8.0 magnitude earthquake (50 miles away). The bridge includes dampeners that are aid to minimize (not stop) the bridge's vibrations.

In May of 2002 A Magnitude 3.3 earthquake struck 14 miles southwest of Grand Canyon Village. The area near Grand Canyon Village is one of the most seismically active areas in Arizona. Although seismic hazard is low in much of Arizona, it is significantly higher in the Yuma and Flagstaff­Grand Canyon areas. Yuma is designated as having a high hazard level because it is close to active faults in the Imperial Valley in southern California and northern Mexico that have generated numerous magnitude 6.5 to 7.0 earthquakes during the last 150 years.

Grand Canyon has announced the Skywalk's official public opening date will be March 28th 2007
