I’ve seen some crazy urban climbingvideos in my time, but this one takes the cake.  It was captured on a helmet cam and follows four teenagers as they scramble up the Moskovskyi (Moscow) Bridge in Kiev, while traffic rushes by below.  After a brief conversation in Russian at the beginning of the video, the teens simply begin scaling the steel cables that hold the bridge in place, without the use of any kind of climbing gear or safety equipment.  Eventually they reach the top, and even climb inside the main tower, which stands some 377-feet in height. 

Judging from the final shots of the video, I don’t know what would be scarier.  Climbing the bridge, or making your way back down.
