But the bridge had _no_ apparent protections even for those 3000 TEU ships. Port of Baltimore spent considerable (federal) funds dredging the harbor to make way for Panamax. A bog standard ring of rocks or concrete or steel piles could have dissipated enough energy to have a very different outcome. I’m just asking, should not the obligation for reasonable protection of the bridge be on the government or port authority?
