The concept art for the Grand Canyon Skywalk was arresting . But the real glass pathway , jutting 70 - feet out over the drop-off edge , 3/4 of a Admiralty mile over the river bed , promises to be far more so . What does it take to bring a labor of this order of magnitude to life ? A million pounds of steel , and 90 gross ton of tempered glass , apparently . Here are some of the first shots of the walkway ’s construction , good manners of the LA Times ’ feature on the structure .
I ’m not sure I have the guts to take the air out over it . My faith in engine room and materials science simply does n’t extend that far . You ?
