Was hoping to get more information from the state engineer about this bridge, and they have no historical data on this bridge.

A slam-dunk as far as I'm concerned with this being a WIBCo. span.

This very similar one I visited in Morrow County, Ohio a couple years ago dates to 1874:

Thanks, I was just curious, trying to learn as much as possible as I go along.

Details that identify this bridge as a WIBC bridge include:

-Use of cast iron splice plate between end post and top chord beam.

-Threaded rod and nut connection for the diagonal member connection with the top of the end post.

-Threaded rod and nut connection for the bottom chord connection with the end post.

-Use of rolled Tees for built-up vertical members (as opposed to paired angles) and the use of one set of lattice between the tees.

While other bridge builders might have used one or two of these features, the use of all of these together make it nearly certain to be WIBC.

May I ask what stands out that makes this a Wrought Iron Bridge Company Bridge?

Looks like a relocated and very good unaltered example of a Wrought Iron Bridge Company bridge.
