NBI gives 1910 build date, likely for abutments. Wooden superstructure probably dates from the rehab year of 1976.

Oh yeah, probably. Time and again I've combed through NBI database lists and found where a bridge's type changed but its build year was kept the same.

I believe the NBI's 1910 date for this bridge applies only to the concrete abutments, while the superstructure, which is a typical wooden slab, likely dates from 1976. It was and remains fairly common in Michigan for small-scale timber bridges to be built on top of the substructure from the previous bridge, and it is also fairly common for the NBI to count the substructure date as the build date for the entire bridge.
