It is certainly a reasonable question to ask that after the Sunshine Skyway Disaster (which is relevant unlike the I-35 collapse which is not) why were all major bridges that span port access not retrofitted with "massive dolphins" if the piers were in the water. Most other East Coast ports do not have this narrow an entry (Savannah has piers on land, Philadelphia's narrowest bridge on the approach has a center span 400 longer, both Norfolk and Charleston don't have any bridges at all on approach). In the grand scheme of costs and how much the Federal budget is, this would be pretty small amount of money.

Definitely a question which needs to be addressed. As is typical, commentary is to the extreme in terms of the number of bridges this could happen to even if, for various reasons some listed above, it is unlikely to happen. How about addressing the most vulnerable and work back.
