This is a beautiful engineering masterpiece and I'd love to see it.


I think it's a scar and a blight on the surface of one of nature's masterpieces, and a shameless act of commercialization and exploitation to boot (you think it's FREE to walk around out there?).

Bah. My cynicism just grew another wart.

It looks quite exciting. But, I don't believe the OP that the structure jutting out over the canyon will support 72 million pounds, 72,000 maybe. And I don't believe that the structure jutting out over the canyon contains a million pounds of steel beams, not even a million pounds of materials. Please recheck the numbers or give a link.

Them crazy horse injuns been hangin' 'round the palefaces a bit too long. Exploiting and raping the holy land:

"They've been able to exploit their natural beauty and become a tourist destination," "and plans are on the drawing board to construct a tram from the canyon rim to the floor. Ditto for an anticipated high-end resort and a campground, which will house about 50 cabins and be able to accommodate 200 campsites and 200 recreation vehicles."

Trams from the rim to floor????
Gol dang firewater!!!
Hey, let's charge everyone five bucks to toss a rock into the canyon and see how long it takes to fill up!


I think it would be better to give all tourists a handful of hits of acid or shrooms and let them have some 'fun'.....a better trip than a tram!

Yes, I know that is odd, but a lot of people feel the same. The edge of a high building is creepy. Looking out a plane window is cool. Someone said it is because you're enclosed in the plane, so don't feel vulnerable. I don't know.

It's an ideal facility for the Indians to set up slot machines. - If someone gambles all and loses Sad he could just scale the wall and jump ... Wink

Funny thing about the Grand Canyon. One of the most awe-inspiring sights on the planet yet it holds little charm for those who live on its edge. A tourist draw & not much else. Make tips off the tourists, sell some postcards. The kids who attend the small school on the south rim are bored & prone to delinquency. The grandeur is lost on the locals. When I was there a longtime resident got hammered on beer & took the big fall. Not talking native indians here, but the white community.

If the residents can better their lot through this project, more power to them. This "skywalk" would be a relatively small impertinence on the environment -- there are already roads, rails, & lookout stations. You can look down on where mining companies took chunks out of the landscape. No sense pretending its pristine (LA smog & countless sightseeing helicopters out of Las Vegas).

But it will always be a wonder & well worth a visit.

Thanks for the links. The data in this thread do indeed match the links. It's still obviously not true. There could be a million pounds of steel beams somewhere in the area, but no way is there a million pounds of material in the sky walk shown. Further, there is no way that skywalk will support a load of 72 million pounds. This is sales talk and probably comes from some PR/sales person who had no basic understanding of any physical science or engineering (or it's bald faced fabrication).

A million pounds of steel I beams would be enough to build a major structure. If you stand in a large parking garage (at least 3 stories and 500 cars) and look around you at all the steel beams, that could be about a million pounds of steel. Now look at that picture of the sky bridge. It's mostly glass as well.

Further, it is cantilevered horozontally out over the canyon. It needs to be light, not heavy. It is designed to support 120 people. 72 million pounds. No way. Send this to a civil engineering web site and wait for the howl.

I would guess less than 2500 pounds of steel and a maximum load of 180,000 pounds. Perhaps some crazy PR guy multiplied the real numbers by 400.
