Interesting data point:
After posting that I tried to think of other ports in the US that both serve deep water large shipping, have to go under a bridge to get there, and have a relatively new bridge. New York and SF are obviously old bridges, as is the Delaware Memorial Bridge (over the Delaware River).
The San Diego-Coronado Bridge looks to have extra pylons/fenders added to it at some point.
Most other large ports I can thing of are either not behind a bridge, or the bridge has been there for 50ish years. So I'm not sure how prevalent anti-ship pylons are going to end up being in new construction. Looking at NY and S harbor on satellite views, this might be a good use of some of those infrastructure funds. Dropping the Golden Gate or Verrazano Narrows Bridges would be a much bigger deal economically than Baltimore is.
