This bridge was a very unique find, sitting in a field near Egan, Illinois.
It appears the landowner has preserved the structure, for reasons unknown. However, one can get a good idea of how a stone arch works by visiting this structure.
The celing is exposed, and a clear path to the structure has been created. The bridge was likely built to cross a cattle pass or possibly, a small stream.
Otherwise, the bridge is a typical type of stone arch, with mortar solidifying the joints. It was likely built in the mid to late 1890s to replace a trestle span.
It is recommended to recieve permission before accessing the bridge. Overall, the bridge appears to be in excellent condition.
The author has ranked this bridge as being locally significant, due to the common design.
