scientists haven't perfected transparent aluminum yet (Scotty only gave us the formula some 20 yrs ago), so glass is the next best thing. plastic would be stronger, but solar radiation, extreme desert heat and foot traffic would ruin plastic pretty quick.
I thought it was going to be enclosed. From that picture it looks like its just a catwalk What keeps suicidal maniacs from jumping and children from falling over the side?
It looks like a waist high rail is the only thing keeping people from falling. I can't even tell if there is glass between the posts that hold the rail up. If not, there is a enough space for a horse to fall though there! Dosn't the government have any safety standards for indian reservations? Walkways over highways have better safety measures then that!
I'm sure we'll see the elegant walkway adorned with 6ft chain link before long. I'm not 100% certain how the US <-> Native American Sovereignty rules work, it does give them a lot of lee-way but I can't see public endangerment as one of those flexible items.
I was thinking more along the lines of th 10 foot chainlink with a hooked top, like can be seen on top of the empire state building and in many prisions and mental hospitals
who lives closest to that place? maybe he could go and take a closer look at it and make some pictures for us to examine... like the view, materials etc. would be cool...
I'd go myself, but it just happens, that i live half the world away.
I wonder if the design incuded provisions for working on the bottom? Maybe some kind of rails along the inside edges of the steel frame to allow some sort of rolling platform to be used. It would be interesting to know!
