Salt mines in particular are of the safest kind in the whole world, they are super stable. It's a self supporting rock with enough plasticity that the whole thing doesn't crumble down.
If you ever have privileged info of a huge earthquake happening, going into a salt mine is probably not the worst idea.
Plus it rehabilitates your lungs to be in a salt mine for a long time.
What happens when they run out of salt? All the salt they put on the roads must end up back in the lakes but not in a way that is as easy to extract, right?
Out of many worries about this world and its future, running out of salt is really at the bottom of the list.
You can always extract it form the sea by mere evaporation like our ancestors did. Plus salt deposits in the ground all over the world are massive, we had salty seas for billions of years.
The largest salt mine in the world is under Lake Huron: https://www.compassminerals.com/who-we-are/locations/goderic...
My initial reaction was fear.
But then I wondered if modern mining engineering is a solved problem? In that they mostly know how to make safe tunnels?
Then I looked up how deep Erie is and it’s pretty shallow, with an average depth of 62 ft!

It what?
Like victorian doctors prescribed sea air for healing. When it didn't work they prescribed country air.
Would highly recommend the book "Salt" by Mark Kurlansky. I never realized how influential salt was to the course of human history.

Not sure why you're getting downvoted. People shouldn't get punished for asking questions.
