Patoka River Bridge

This one used to have a through truss with it... That was built in 1887. Unfortunately it was replaced over 30 years ago with the slab. The pony is riveted and is probably built around 1910-20. It does appear that at least one cut stone substructure element does remain.

Ha! Doubt if this was built in 1887
