Before lunch or after?

Set to be completed early next year, this bridge will stick out 70 feet from the base, and will be suspended 4,000 feet above the Colorado River in the Grand Canyon. It's been tested to hold more than 35,000 tons, withstand 100 mph winds from eight different directions, and handle a magnitude 8 earthquake within 50 miles of its location.

Oh, I guess I didn't mention one other key point: the bottom and sides are made of 4-inch-thick glass. Would you walk on it?

Here are a few links on the bridge.
