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 structure 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 Skywalk

Still makes one wonder if you want to walk out on the bridge

Nice to know other Bridges
The bridge (or should it be called tunnel) goes under water to allow movement of ships . In order for ships to pass, this bridge is half under the water. You drive down in the water and then come out on the other side. Truly a marvelous piece of engineering!? This bridge is between Sweden and Denmark Picture taken from the side of Sweden.
