I could never walk it but I am fascinated by how it was built. Those were brave souls.

I agree. Went up to the observation deck of the Sears Tower once, it is all glass enclosed, still I could not get closer then 6 feet to the windows without the stomach starting to feel queasy. There is no way I could walk that trail.
I gather it was built in the early 1900’s so it was probably done mostly with manual labor and maybe a little dynamite.
