|I've heard horror stories about these pile-ups. Hopefully, I won't witness any first-hand soon.
Unfortunately they are a reality of I-70.
The best one yet was about 4 years ago. I was in Aspen and getting ready to head home. Apparently a trucker decided to load up on cocktails in the early AM while they loaded her tanker with hot tar. She decided to speed down the hill and didn't make the curve at the bottom at about 6 AM. Spilled hot tar completely across I-70 and shut it down for about 8 hours. Massive traffic jam. Utterly no skiers made it to the hills that day. When I got to the part of I-70 that it is usually jammed with cars - clear sailing. The ski resorts lost uncounted millions that day..
Saw something similar there this past spring only it appeared to be the crumpled, twisted remains of some type of big pickup truck. Traffic was backed up to Golden. Didn't matter too much cause I-70 was also closed at the tunnel due to weather conditions. I was already in Empire and headed home due to high wind/Berthoud Pass avalanche closure so I just saw the whole traffic mess as I drove by.
