Got this in an email and thought it was wild! It might be old footage(I don't know), but none the less, it's pretty extreme.
This 3150 m long tunnel in Russia is the longest in-city tunnel of Europe.
There is a river running over it and water leaks at some points. When the
temperature reaches -38 degrees like it did this winter, the road freezes
and the result is the attached video taken during a single day with the
tunnel camera.
I wouldn't like to be on that bus..
I think I'd stay home... what do you think?
