Coincidentally, we saw six of those blades being transported west on I-80 Saturday while driving up to Omaha. Funny that these are going east.
I believe the far-right car is the last in that train. It was a huge train. I took pics from the Haymarket parking lot and it was going by, slowly, at the time. I then drove over to 1st & O street, parked, walked 200 yards up the walking path on the O street viaduct, and took that panorama, and the train was going by the whole time.
EDIT - to my knowledge, those are not being put up in or near Lincoln. There are several large wind farms along I-80 through Iowa, so I'm guessing they're going there.
EDIT II - we have two wind turbines in Lincoln, more for show than anything else I believe. They're up north of the Interstate on 70th street. You can drive to within half a block of them, and when they're in use the blade tips sound like jets whooshing by.
