To elaborate on Mike's description the truth is the entire stone arch was encased in concrete in 1958 in addition to railing replacement. See my photos here: https://historicbridges.org/bridges/browser/?bridgebrowser=m...

Some notes:

This is an interesting example of a bridge having one set of historical railings replaced with another, as the original balustrade railings (shown in the postcard) were replaced with the Michigan-distinctive "R4" railings (shown in the StreetView) when the bridge was repaired in 1958. This does appear to still be the same bridge otherwise, however - the Fenton Mill Pond has a couple hundred photos to go through, and the bridge can be seen in some of them.

MDOT also de-commissioned Business Route 23 through Fenton on December 7, 2006. The history of that particular route has some odd nuances as well, and those are documented on the Michigan Highways link that I've added.
