A Leap of Faith?
The Grand Canyon sky bridge reminds me of a scene in the movie Indiana Jones and the Last Crusade. One of the clues asked the seeker to step into what seemed like a deep chasm. In reality, there was a nearly invisible bridge that crossed the void. Indiana referred to this as a test of faith (he passed).
Your faith in Terra Firma might be tested too as you step out onto this glass-bottomed bridge suspended over the Grand Canyon. The Skywalk juts out over 65 feet from the canyon wall, and the bottom of the Canyon is a mere 3,600 feet down between your feet.
The Grand Canyon sky bridge is being constructed on land owned by the Hualapai Nation at Grand Canyon West. The glass and steel, horseshoe-shaped skywalk will jut out 70 feet from the Canyon rim. Visitors (the ones who actually can be coaxed to walk out on the thing) will look through glass walls and floor to the Colorado River far below.
It's engineered to be able to hold 71 loaded 747's, withstand 100mph winds and nearby large earthquakes. So though it sounds scary, it's designed to be very safe (just don't tell your thrill-seeking companions).
Opening day is being eagerly anticipated, but it might be awhile. The Grand Canyon sky bridge won't be completed by June '06. The Hualapai Tribe have announced a delay due to added features. The skywalk should be open near the end of 2006. Eyewitnesses report that two big holes in the ground are all that can be seen in fall/winter 2005.
UPDATE: It's open! Opening day was marked with Native American ceremony and lots of national press coverage. Even Good Morning America sent someone over the edge. Visit Grand Canyon Sky Bridge to learn more and reserve your tour. The total price will be at least $75 per person regardless of any other reports you've seen with lower prices. These reports are not taking entrance fees etc. into account. Be prepared to spend the $75.
Some things you need to know about visiting the Grand Canyon Skywalk:
The summer is HOT. The Hualapi lands where the Skywalk is located are only at about 4,000 feet elevation. If you must travel during the heat of the summer, the South Rim is a better choice. It is some 3,200 feet higher and comfortably cool (at least in the shade!) through the summer. South Rim air tours are always available too.
If you want the Skywalk experience, I recommend traveling during the spring or fall unless you can handle to the heat. Bring a hat and water during any season and a jacket if it's cool.
