Possible Naval Yard Bridge photo?

[Rhatkinson]

I would love to hear the opinion of the resident experts on whether this picture of the Washington Arsenal could (I stress could) show the Naval Yard Bridge in the background. On initial inspection, you would think not as the picture seems to be taken looking west (and thus towards the "Long Bridge".) However, there are some problems with that which make me think this picture is actually reversed. Check out the original:
   

and now look at it reversed/mirrored:
   

One main reason that I believe the mirrored shot may be accurate is that the East Potomac Park, which is separated from the arsenal by the Washington Channel (and was back in 1865 as well)
   
is not pictured. Rather, all you see is open water behind the arsenal. Check out the current view from East Potomac Park and see what you think. (I wish I could get a view from higher.)
