Grand Canyon Skywalk: All Glass, 4,000 Feet Above the Canyon Edit

If your Grand Canyon helicopter tour from Vegas isn’t thrilling enough, you may want to check out the GC from a glass skywalk that towers above the canyon.  We need more of these.
“The view may terrify you, but there’s no cause for alarm. The Skywalk, which juts out into the air some 4,000 feet above the Grand Canyon floor, promises to be as safe as a trip to the fridge. The super-strong structure is anchored to four bedrock footings with 88 steel rods. Altogether, the steel and glass Skywalk can support 34,000 tons (think 71 fully loaded Boeing 747s). It’s designed to handle 100-mph winds and withstand a magnitude-7 earthquake. ” - Wired

From the Destination Grand Canyon Website:
The Glass Bridge Construction of the Skywalk began March of 2004 and is estimated to be completed by early 2006.

Upon completion, the 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 stucture 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.

Design-tested by a world-renowned team involved in such projects as:

The Palms Hotel Casino
