Volgograd Bridge, Russia: During a violent storm in May 2010, the roadway began to shake and oscillate, in a similar manner to the Tacoma Narrows Bridge before it collapsed in 1940. The rippling roadway caused cars to be thrown into the air and careen into the opposite lane. Authorities blamed it on an earthquake, but seismologists disagreed. Where: In the southern Russian city of Volgograd, crossing the Volga River. Stats: 4.5 miles long.
