[Tolerance Sucks Rocks]

Colorado often closes I-70 that sits at the bottom of a huge, long cliff - where rock and mud slides, avalanches are common .. Pro-tip , should have built it on top of the cliff..

Glenwood Canyon, by any chance? I drove through there, twice. Very scenic, but you can get rockfalls onto the roadway.

Glenwood Canyon rock fall killed his wife and 2 children in 1995 ..

2010 - Art Daily motored through the same canyon only two hours before another cascade of rock punched holes into a bridge and blocked the highway.

This time, no one died.

Glenwood Canyon, drive several times weekly.

Beautiful stretch of road, that can be prone to rock slides, mudslides, and flash floods with the slightest bit of rain or snow. The Official Detour is about a four hour scenic drive.
