The 3,150 meters long Lefortovo tunnel in Russia (near Poland) is the longest in-city tunnel in all of Europe. It is nicknamed 'The Tunnel of Death.' See for yourself why. There is a river running over the tunnel and water leaks through in some areas. When the temperature reaches 0 C (32 degrees F) like it does during the winter in Russia , the road freezes and becomes a sheet of black ice. The result is the attached video, which was taken during a single day with the tunnel surveillance camera. Congratulations to the dual-carriage (articulated) bus driver - imagine the passengers in the back! What a ride! The next time you complain about traffic, remember this video ... Yikes, Russian engineering! .. Or ... Perhaps it's the vodka..?
