The "Remnant" of what was once a combination bridge consisting of an 1887 wrought iron through truss and this riveted Pratt pony that was added probably ca. 1915. Unfortunately, the more historic through truss was replaced about 1985 with a slab structure.

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
