Tunnel in Russia.....

This video is from a tunnel in Russia that 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 -20 degrees like it did a few winters ago, the road freezes and the result is the attached video taken.

 

It was taken during A SINGLE DAY with the tunnel cameras.  Congratulations to the dual bus driver...This is better than turn 4 at Daytona. Remember-- this is only ONE day of video.
