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.
Congratulations to the dual bus driver .... This is better than at
Daytona.
Wear your seatbelt!
