 So they finally got the glass looping walkway that goes out over the Grand Canyon built. Apparently it opens to the public on the 28th of this month. It looks like a giant horseshoe that is tacked onto the side of the canyon wall. It is glass in the center so you can look straight down into the canyon. There are two huge beams that the glass stretchs between. Additionally there are high glass walls on edges of the walkway. It isn't a solid piece of glass though and is instead just panels.
