Yeah - putting twice as much traffic on an already congested commute is going to be a nightmare.
It was the Oso, Washington landslide. They just had the 10 year anniversary and finished a nice memorial at the site. It wiped out a very rural neighborhood up in the mountains alongside a river. 43 people died, 49 houses destroyed.
I don’t think too many people “commuted” along that road, but those trying to get to doctor visits, etc. and getting food and supplies up to the upstream towns was a hassle.
I just looked - the 2-lane highway was reopened 6 months to the day of the slide. However, a one-lane gravel road was completed after 3 months. I don’t know if that was open to everyone or maybe just critical things. Obviously still lots of construction going on. The slide took out 600 feet of the road. The road was at the tail end of the slide run out.
Thanks for the information on the Iso Landslide. I may have heard about it when it happened. I’m sure it was reported her on FR at the time, but don’t recall. Landslides are devastating. I can’t even imagine what those poor people went through, and those that are left will be grieving for those they lost, for the rest of their lives.
