Grand Canyon's Skywalk




CNN.com

Skywalk to offer thrilling Grand Canyon view

By Adam M. Bright
Popular Science
Thursday, May 11, 2006; Posted: 11:31 p.m. EDT (03:31 GMT)

Take a stroll over the all-glass Skywalk, and you can hover above the Grand Canyon.

(PopSci.com) -- Step out onto the new Skywalk, and only a few sheets of glass will stand between you and a 15-second free-fall to the bottom of the Grand Canyon.

Set to open late this year, this horseshoe-shaped footbridge (commissioned by the Hualapai Indian tribe, which owns the land) will jut 65 feet from the cliff edge and suspend 3,800 feet above the canyon floor, a height more than twice that of the world's tallest skyscraper.

If you're a bridge, the Grand Canyon is probably the last place you'd want to be: 90 miles per hour vertical winds whip upward with tornado-like force, a condition endured by no other bridge in the world.

To secure the Skywalk, Lochsa Engineering in Las Vegas has cantilevered it atop the cliff with 94 steel rods that bore 46 feet into the limestone rock. As a result, it can support 70 tons of weight, equivalent to roughly 700 hefty men, although the maximum occupancy is set at 120 people.

Three oscillating dampers -- steel plates, each 3,200 pounds -- inside the hollow bridge beams act as shock absorbers, moving up and down to neutralize the vibrations from foot traffic and wind gusts. For further support, the walkway itself will be constructed of three-inch-thick, heat-strengthened glass and enclosed by five-foot-tall glass walls.

Too tame for you? Lochsa hints at future plans to ratchet up the thrill factor by turning a maintenance car designed to run on a track along the bottom of the Skywalk into a trolley ride for visitors.

It looks like the glass goes way above the head, that helps with fear of heights [a little]

Very neat idea, I like it!

I should be ashamed; I live in Arizona and I didn't know about this until I read the thread. Anyways, it's a great project and it'll contribute greatly to Arizona's tourism, for all those risk takers that wouldn't mind trying it out.

I might even try it next time I visit.

Just watch the number of tourists in Toronto drop severly, and Arizona's tourism skyrocket.

Glass floors freak me out. I barely stepped foot on the one in Toronto.

Though I did pay $600 once to walk the "halo" outside the observation deck at the Space Needle. Tied in of course.

Good idea !

Then I fell asleep in her arms.
That was happiness then.
