Dang! Weird that I hadn't seen anything about it online. I don't have TV (just netflix and youtube), but I usually see stuff like that on the Facebook page of the local news.
Most of the roads here are it as well. Road is shut down, you wait. Might be a few hours, might be a week, all depending on what happened.
Really surprises a bunch of folks down here when even a minor highway gets taken out, be it flooding, land slides, wrecks, Evel Knievel listening to too much Grateful Dead...
We got mountains on the right, and water on the left, with a bunch of tight spots up and down. And a boat load of towns up in the valleys that only realistically have one way in or out, in the best of times.
