hmmm....southeast NE might be next on the list, then!!
Nick, it is funny you mention Nebraska. I honestly think that Nebraska might be the most underrated state in the USA when it comes to historic bridges.
I have never lived in Nebraska, but I have driven through it many times. Thus, I have been able to visit a few historic bridges there. Nebraska has some nationally significant bridges, but many of them are in very rural areas that are not always easy to access. The southeastern part of the state seems to be the most truss-rich area of the state from what I can tell. Kansas just keeps us all so busy...
This one disappointing. Town of Odell, Nebraska 2 miles to the north more interesting.
There is definitely some good stuff up there. Unfortunately, Nebraska did demolish one of its most significant bridge is back in 2001 when they destroyed the O Street Viaduct in Omaha. This was the last known remaining Whipple truss in Nebraska.
The state still has some very unusual bridges built by the King Iron Bridge Company. It also has quite a few Bowstring Bridges too. Unfortunately, I am not as familiar with Nebraska as I am with Kansas. I just haven't had the time to research Nebraska records or do aerial scanning. I have found quite a few Kansas Bridges thanks to Historic Aerials and Google Earth. In fact it was historical Aerials that led me to the abandoned Kansas River Bridge off of Rosencutter Road just south of Manhattan.
I am glad that you have been getting into North Central Kansas as well. There are still some great bridges up there as well with most of them being Pony trusses. As you know I was farther west in Norton County recently and there are some really awesome Pony trusses out there. They are small but they are also extremely unusual and rare.
