Grand Canyon Skywalk - "My vision was to enable visitors to walk the path of the eagle…" said David Jin, creator of the Grand Canyon Skywalk. The glass bridge juts out 70 feet from the edge of the cliffs above a 4000-foot drop to the bottom of the canyon on the West Rim.
The Ledge at the Willis Tower Skydeck, Chicago - Visitors can step outside the tallest building in the Western Hemisphere into boxes made completely of glass. These glass balconies (as they're also known) sit 1353 feet in the air off the side of Chicago's Willis Tower.
