I just saw this Bridge yesterday while looking for The Town of Columbia, WI. On one of the main Roads into Columbia, WI there is a Railroad Grade that goes into the abandoned Town of Sidney, WI very close to Neillsville, WI. The Grade comes up to the old Highway 10 (Now County Trunk B). And there used to be a overpass over Old Highway 10 (Now County Trunk B). That Grade goes all the way to the Railroad Bridge across Wedges Creek.
I've seen both names used. Feel free to change the name/feature crossed.

Pretty sure the name of the waterway here is "Wedge's Creek."
My recent research failed to find information on this bridge. However, the one other double truss along the Omaha Road route is of identical length and was confirmed to have been built out of recycled trusses of the 1881 bridge at Hudson, Wisconsin. I suspect it may be a similar situation here.
