Here’s another one from Damn Interesting, that is… well, you know (thanks, Deane, for the new compulsively readable link.) A new tourist attraction is being built at the Grand Canyon that features a glass walkway that juts 70 feet out into nothing, 4,000 feet (about 1200 meters) above the canyon floor. $25 will buy a walk — or crawl — around the horseshoe-shaped structure. I get the heebie jeebies just looking at pictures of the thing.
The engineering firm designing the thing is way overbuilding it; it will be able to hold up to 72 million pounds, to deal with the people load, the wind load, possible seismic activity, and of course the occasional jerk who feels the need to jump up & down on the end of the thing to see if he can make it bounce.
The Skywalk is slated to open this August, but the park is having trouble finding someone willing to write an insurance policy to cover it.
