This video was e-mailed to me today with the following text:
This 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.
Hell I think it looks like 275 everytime we get a good rain. Anyways, enjoy.
