Tiderishi Ditch CR59 Pony Truss

In fairness, while these welded truss bridges are not historical, they aren't completely worthless. They are certainly much more interesting than the typical UCEBs constructed everywhere else.

It's satisfying to see that the art of building truss bridges isn't completely dead or obsolete. We've already lost most of the practical knowledge of how to build stone arches and other historical bridge designs; let's hope the same doesn't happen to truss bridges. While these modern Warren trusses are quite a bit different than the original designs from the days of Mr. Warren, they do carry on the tradition.

Historic preservation isn't just about saving old structures; preserving the working knowledge and techniques behind the structures is also important.

Of course, there's no point in photographing every one of these things. They are quite common in Ohio and a few other places. But there's no harm in showcasing a few of them as an example of how truss bridges still have a place in modern engineering.

As an aside, these modern bridges can produce a surprise or two. Maybe there's an original stone pier underneath, or maybe the design is rather unusual. Take, for example, this welded truss in Missouri:


I did a double-take when I looked closely at the girders and realized something didn't seem right. Indeed, it's actually a Howe truss -- not the Warren or Pratt that I would have expected. This might be the only metal Howe truss in Missouri that carries traffic. It's not historically significant by any means (built in 1995), but that doesn't mean it isn't interesting.

No offense and not to discredit your photo but these bridges are all over Ohio and have no historical value.
