It's a common theme for Google Maps to mis-name streams when they get close to their confluences.
On the subject of the NBI, is anyone opposed to merging the 96 NBI data?
It seems fairly spot-on to me.
It looks like Google maps has misnamed this waterway.
USGS calls it Big Creek:

So this is probably the bridge Luke found in the 96 NBI.
Looking at Bing maps, it appears there are other former crossings on this stream, the bridges long gone, except for what appears to be a pipeline? bridge at 40.926256, -91.550704.
The 1996 NBI lists a closed bridge dating to 1903 over Big Creek:

Span length seems to match IMO.
This one's for you, esp. those residing in Henry County. Can you help crack this case? The 97th mystery bridge takes us to Iowa, to Henry County, to a historic bridge over Skunk River that is unknown- no history, no record and no photos. Can you help solve this case?
