In my original posting for this bridge, I noted that barge traffic in both directions used the south navigation channel. On the day I took these pictures, barge traffic was using the north channel. I have no clue what influences a captain's choice of which arch bridge to go under. (Update: I have seen evidence that Lock and Dam #52 is still operational. During today's visit, they had to use the lock, which is on the north side of the river. During my previous visits the wickets were down so they had the option of using the south side of the river.)
I then put on the telephoto lens to get close up pictures. In the background of the middle picture you can see the Blue Hummer Bridge.
a Goggle satallite image, but it did not have the pier. So I switched to FlashEarth. All of the above pictures were taken from that pier. I then took pictures downstream and of the fort from the pier. While I was taking pictures, my wife went to check out the fort. But she was advised that it was closed because a fugitive was loose in the area. There is a bend in the river so that you can't see the railroad bridge in the downstream view.
