Imagine the task of taking it down. I doubt they could just blow it up
because of all the sediment that would put into the river - and
ultimately into the Chesapeake Bay.

I don't think it's possible for it to rise anywhere near that high... on
second look at the pictures I did just notice the high water marks that
do go very high! I sometimes go boating there (there is a public boat
ramp at the south end) and I'll have to take notice how much room is
under the bridge from its highest water marks.

The object in the forground of one of the pictures looks like an old pump
previously used to pump water from the canal at the bridge. Is there another one
installed on the bridge?
