Alum Creek Bridge

Description 

It is very unlikely that this bridge still exists. The current CR 340 is nowhere near Alum creek, but does not cross anything bridge-worthy. Judging by the fact that the other listed bridge crossing Alum creek was on CR 347 that is now CR 332, it appears that Wilson county renumbered its' roads. The other possibilities for bridges on Alum creek that could have been the old 340 are CR 421 and 422. From looking at Google maps, both crossings are relatively out in the open, and there are no shadows that would be visible from the trusses if they were there.
