UP/C&NW Bridges over the Missouri River at Blair, NE

1883: (Bridge Hunter "Built 1883; superstructure replaced 1923-24; spans relocated to cross Wind River in Wyoming"; HAER) That would explain why the piers are still made with cut stone.
1924: (Bridge Hunter "Reportedly a second bridge is to be built adjacent to this one in order to increase traffic capacity, the line is single track at present."; no Historic Bridges; Satellite)

From the satellite image we can see that one of the three spans is over a flood plain.

We're looking southeast at the iconic bridge in Blair that spans the Missouri River and separates Iowa from Nebraska. Home to Union Pacific's Blair sub, we spent some time here waiting, but unfortunately we weren't able to see anything run on this stretch of track.
