I don't think the U.S. feds consider it a national security priority. The redundancy argument can be made for natural disasters, accidents, etc. -- stuff that can and has closed the bridge -- but not really for terrorism. The terrorist attack meme is pretty silly because if the terrorists can defeat the post 9/11 security to get on the bridge with enough explosives to actually destroy the span, you'd think they'd be smart enough to remember to blow up the other bridge that's within site of the first one.

I think we'll get a good sense soon of what the Congressional and administration's view of taking over DRIC will be. This seems like the golden PR moment for a federal lawmaker or for the administration to look like a savior. The administration is committed to infrastructure, so it's possible. Just haven't heard much federally since DRIC took off in 2002.
