Frightening moments when survivors try to pull themselves to safety after a Minneapolis bridge collapses. In the middle of a rush hour traffic, it all came to a stop. With cars falling off in what seem like a disappearing act. As authorities try to figure out what really happened, all one can do is pray for the survivors, victims' families and injured victims.  http://www.cnn.com/2007/US/08/02/bridge.witnesses.ap/index.html?eref=rss_mostpopular
