The joints on this bridge are currently being replaced. A joint broke in April.
Just to verify, all of the photos displayed are, in fact, of the I-24/I-69 bridge over the Tennessee River (Calvert City, KY). Photo #1 may be compared with the sunset image I've uploaded, taken this past Sunday (5-13-2012) from below the Kentucky Lake Dam (compare the hi-tension towers in the back ground).
I think photo #1 is the bridge at Paducah
With all respect, I am pretty certain that the caption of photo #4 (Ben Tate-August-2013 " As seen from Cumberland River US 62 Bridge") should read "....US 62 Tennessee River Bridge"
Maybe someone could correct the caption.
