IORY - OH-109 Overpass

This one was kind of tricky to ID as an encased plate girder aside from the "squares" in the concrete on the fascia (the squares being formed by the girder stiffening ribs). As for Monroe County, MI and also a couple in Lenawee County if you check HistoricBridges.org you will find I had those Michigan examples listed as metal girders. I unfortunately do not know how to automatically add a HistoricBridges.org link on Bridgehunter pages I can only do it manually and I don't have time to link 7000+ pages. James did make me a workaround system to automatically generate a BridgeHunter link based on distance which allows me to offer automatic links from HB.org to BH.com but that won't work in reverse as I cannot figure out how to create a similar tool for HistoricBridges.org, nor add the needed linkage in Bridgehunter in an automated manner, as I am nowhere near as skilled at coding as James was. So you will just have to remember to check HistoricBridges.org manually!

Interesting...I hadn't realized that this was a steel girder bridge, I just assumed that it was a rather artistic concrete girder....but then I just did a quick flyby visit when I took a picture of it. Strange that the design differs from the IORY overpasses over 424 and 6 when the dimensions are very similar.

Now that you mention it, I think this bridge in Monroe County on the same rail line also has encased steel girders: https://bridgehunter.com/mi/monroe/bh94320/
