I agree with Roberts assessment-it looks like the stone piers had about a foot of concrete added to the tops after the removal of the previous bridge (probably a large truss), and intermediate concrete piers designed for two side-by-side bridges were added. It looks like the second bridge was never added, though, as it appears that the concrete surfaces have anchor bolts installed, but are otherwise unscarred.

There is a similar situation in Marinette WI / Menominee MI at a railroad bridge crossing the Menominee River - old stone piers, with newer concrete piers between them. I don't have any historical photos, but my guess is that the stone piers were built for an earlier truss bridge with longer spans. When the railroad upgraded the crossing to carry heavier loads, they opted for short plate girder spans with additional piers as a cheaper alternative.

There may have been another girder bridge, but that line fell into disuse, and the railroad found another place where it could use the girders.

An interesting story suggested by the piers. It looks as if there are a couple of older stone piers. The concrete piers look wide enough for a larger bridge. This plate girder probably wasn't the original.
