Here's where it was
Looking east. Beaver Dam Road is a farm road that crossed the river here, continued east for several hundred feet, then angled north. (You can see extant pavement in the distance.) The road was cut by the upgrade of US 41 to freeway status, relegating this section of road, and this bridge, superfluous.
