Surprise rural StreetView strikes again!
And as it happens, this one *just* came online on Google not too long ago (October).
This bridge has become a favorite of mine to photograph, it is close to my son-in-law and daughters' property. Their son who is in the USMC has admired this bridge since he was old enough to fish from it. I am gathering as much information and pictures about it to put together a book filled with the 4 seasons of pictures of the bridge as a Christmas gift. This bridge brings memories for so many.
National Register Nomination Form attached. Does not confirm a builder, claims early 20th Century. I agree with Tony, the Warren truss and also the fishbelly floorbeam pony truss look older. According to form, bridge was moved here in 1950.
Looks like an unusual longer-span example of this:

The unique design was marketed by King Bridge Company's Milo A. Adams who later formed his own company in Minneapolis. His works are known to have been built in Iowa and South Dakota.
This rare pinned Warren through truss is likely a good 20 years or more older than the given build date.
Definitely doesn't look like bridge photographers have to worry about traffic!
