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
The joints on this bridge are currently being replaced. A joint broke in April.
