Close to Las Vegas, The Grand Canyon Skywalk is a glass bridge suspended 4,000 ft (1, 219 m above the canyon; the horseshoe shaped bridge extends 65 ft (20 m) out from the edge. It has been commissioned by the Native American Hualapai Indian Tribe and opens to the public on March 28, 2007.
In such an environmentally sensitive area, the construction of the Grand Canyon Skywalk is not without controversy. The Grand Canyon dwarfs the actual Skywalk but there are fears regarding the impact of further development at the site. ABC recently broadcast a news clip about the project and here is a nice video clip from Staseman at YouTube.
