This simple through girder bridge crosses the Whitewater River near the town of Dover.
The bridge is a single span through girder, resting on stone abutments. However, both abutments have been encased in concrete.
Unfortunately, the bridge is surrounded by private property and only a few photos were able to be taken. I am hoping to get back here soon.
The author has rated the structure as being locally significant, because it is a very common design through this area.
The photo above is an overview looking west along the bridge.
