If the date of 1858 is correct, this is an extremely old bridge. Does anyone have a photograph of it?
Not to interject seriousness into this levity...
But bird's mess can be acidic and bad for metal. This issue emphasizes the importance of cleaning, maintenance, and fresh paint on bridges with extreme bird activity.
If you go to the San Antonio Riverwalk you might notice betting on the underside of the bridges. Of course, this has to do with people under the bridges...
Nice! A continuous pony truss - and a very old one at that! I would hate to see this one disappear. It is quite the rarity, I would think.
Do you have an e-mail address? Could you send me a P.M?
Thanks, John. I haven't had much chance to bridgehunt in that region. This design is almost non existent in Kansas, save for this example.
Awesome! Local support for bridges is paramount. So many preservation success stories begin with grassroots efforts.
This one has been altered a bit, but it is still a great pony truss. Nice find!
Well, that is too bad. Overall, Geary County has done a great job of preserving historic bridges. I would have liked to have seen this one.
What a great find! I would say that the Kansas Default Date of ca. 1910 is probably not far off in this instance.
I have found throughout my travels that locals often take great pride in their bridges.
Thanks, Nathan. I was very surprised when I first saw photographs of this bridge because I immediately thought of the New York example. I didn't recall seeing others like it, which made me think either a relocation job or a railroad standard design.
Compare this bridge with this one:
John? Nathan? Et.al? Thoughts?
Did a Boston Bridge Works product somehow find itself in the middle of Kansas? Was this a railroad standard design built by different companies?
I devised my theory before I realized that there were old limestone abutments under the newer concrete bents. These abutments might match the time period and spacing needed for this Bowstring. In this case, then perhaps this is the original location.
KSHS officially considers this bridge to be NRHP Eligible. I have attached a KHRI PDF above.
Thanks for the input. I was leaning towards possibility #1. I still consider this to be a highly significant bridge despite its alterations and possible relocation years ago.
I have seen photographs of bowstrings that were altered much more drastically than this one...
Upon further review, this Bowstring does not seem to match other WIBC Bowstrings, save for the use of Keystone Columns on the top chord. There is no lacing on any of the verticals or outriggers.
There are three possibilities here:
1. The bridge has been heavily altered.
2. This bridge represents an unusual variation of the typical WIBC design.
3. The bridge was not built by the WIBC.
I am retaining the WIBC category for now, but will note "likely fabricator".
I still have a strong suspicion that this bridge was moved from some other location - even if the move happened a very long time ago.
