Why fly across the Grand Canyon when you can walk:
It is one of the great natural wonders of the world -- and it will soon to be joined by an engineering marvel.
A fantastic glass bridge arcing 60-feet out over the grand canyon -- giving visitors an unobstructed view 4000-feet straight down.
It's being built on Hualapai tribal land, so even the vista on the canyon rim is currently unavailable to tourists. It took nearly a decade of negotiations to get everyone on board, but the hope is tourism will boost the tribe's resources.
