The through truss in Jay County does indeed look very similar to the Oakwood span. The pony I'm not sure about as it looks like it might be of older vintage, despite the 1962 date (which, like you, I am skeptical about).

Wondering if they might have been involved with these two trusses in Jay County, about 30 miles South of Ft. Wayne...

Will do, Tony! Thanks!

Most of the bridges by Ruckman-Hansen seem to be smaller, 70-foot or so steel stringers built 1947-1952 like this bridge: https://bridgehunter.com/mi/lenawee/michigan-avenue/, although I think there was one medium sized pony they did in Indiana. So I would agree with your theory as the Oakwood span seems to be the only large span they did. Of course, we may just not have uncovered other large trusses they did too yet.

Without researching them, my guess is the Ruckman-Hansen were contractors that sublet fabrication for the trusses and stringers to another firm. I hadn't heard of them prior to this.

Paul, if I can ever be of any help with questions on anything bridge related feel free to email me at any time!

Nice find! Incidentally, Ruckman-Hansen built a handful of small stringer spans in southern Michigan at about the same time. This was the first instance I had seen of them building a larger bridge however.


I had created a category a while back for "Ruckman-Hansen" for several Michigan bridges without realizing that it was already listed as "Ruckman-Hansen Inc.". For this bridge I listed the builder as "Ruckman-Hansen Co." of Fort Wayne, Indiana, as stated in the newspaper article, and correspondingly switched all the other Ruckman-Hansen bridges over to this new format, which appears to me to be the most correct terminology associated with this company. The end result was that thanks to my not very efficient way of categorizing bridges constructed by this builder, we now have two empty duplicate builder categories: "Ruckman-Hansen" and "Ruckman-Hansen Inc." of Fort Wayne, Indiana. I don't see a way to delete categories so can you remove these two?

Thanks, apologies for the mix-up; lesson learned to be more careful in the future,
