1877 Bowstring Bridge over, and 1823 Grist Mill on, Rough River near Falls of Rough, KY

The name of this bridge is Green Mill Farm Bridge.

Another bowstring bridge, the Rock Lick Creek Bridge, is just a mile away from this one.

"This is an outstanding example of a mid-1870s King Bridge Company cast and wrought iron bowstring truss bridge." [HistoricBridges] The design is a combination of a tied-arch and a truss.

Kentucky still boasts several rare bowstring trusses, some of which were fabricated by the King Bridge Company of Cleveland, Ohio. Let's explore two of them in the vicinity of Falls of Rough in our latest Journal post, Photographing Kentucky’s Rare Bowstring Trusses:

It is hard to imagine what kind of water wheel this mill used.

I downloaded a higher resolution copy of Hanchey's Flickr photo to confirm that this old bridge was pin connected. But there are very few pin connections. I have learned of an even older connection technology. They thread the end of the members and use nuts.

This photo illustrates that connection technique.
