Oh, it had guard rails... they fell away also... or were flattened by the track hoe that was on site before the news cameras.I have an innate fear of heights, and even driving on roads like that one. (Sheer drop-offs, no guard rails, etc.) Now my personal little inner gremlin feels justified.
Having traveled that route more than I like to remember, it's still there, the chain link is to try and keep it next to the hill, not to keep it from falling. It isn't even attached at the bottom....Don't look up when going westbound from Denver on I70. There's a LOT of rock held in place by what appears to be chain link fencing. At least there was last time I went that route.
