Oh I know this bridge. It crosses the nescochague east of Bloody bridge. I suspect you have been there also Guy. Remember where we parked for the Great Swamp hike? It is directly oppisite there across rockwood road toward and over the nescochague. It does look very old. I suspect it was used heavily during the massive lumber industry in the area in the early 1900's. But that is just an assumption. It could pre-date that.

So you are thinking it is this one just to the left of the arrow.

It most likely is that one. It tells us that logging was going on in the area near the canal. We need to find the Sawmill foundations
