John and I had the exact same thought a couple of days ago.

An article on the construction of the new bridge confirms that they were relocated:

The second Omaha bridge had four 250-foot, eleven-panel Whipple trusses, and two tracks. The first Plattsmouth bridge's two Whipple spans were moved to a Des Moines River bridge, UP moved Pegram trusses to Idaho, and C&NW moved spans from the first Blair bridge to Wyoming. Some chance that these two spans are from Omaha?

Surprised nobody has commented about this bridge. The bridge shows evidence of widespread alteration, since there are a massive number of empty river holes on the portal and sway bracing. My first guess would be that the bridge was narrowed... which also makes one wonder if the bridge was relocated and reused at this location. It would be interesting to know. Finally, taking into consideration the alterations, what I can see of the bridge leads me to believe that this bridge may be the work of famous engineer George Morison. The large lattice portal and sway bracing, Whipple truss configuration, and the arrangement and composition of some of the truss members are what suggests this possibility.
