I have driven down US 31 by this spot hundreds of times in my life and never knew about the abutments. And the talk about old SR 218 alignments piqued my interest. So I went to USGS Earth Explorer (http://edcsns17.cr.usgs.gov/EarthExplorer/) and did some searching. The oldest aerial image they had available was from 1952. I've attached the relevant bit of that image. I drew SR218's modern alignment in yellow. The two curves on its west end aren't actually there in the 1952 image; the road appears to go straight through. I drew in US 31 in green.
If it was the original bridge to those abutments, then it was pre-1900. Too bad they didn't just leave the old bridge standing for posterity's sake.
Funny you posted that Anthony, I was just explaining the reroute to my family a couple of days ago after a visit by the President and Vice-President to Grissom and Kokomo. The former Bunker Hill Naval Air Station was abandoned after World War 2 and reverted back to farm ground, but nearly 10 years later it was reopened by the Air Force. Later, it was given the Grissom name after Virgil "Gus" Grissom of astronaut fame. Indeed the old SR 218 once passed right through the current base. Perhaps it was after Grissom became a SAC base in the 60's when they moved the highway? Now you see, the base itself is very old, so who knows exactly when they realigned it? Perhaps that mystery can be solved someday.
One could assume that this bridge was lost when Grissom AFB was established. SR 218 was rerouted to the North around the perimeter of the base, and that section of CR 600 was essentially disconnected.
