From what I can see from photos, the bridge that was hit by a container ship was more exposed than a bridge of its type should be. I don't see any large protection dolphins, which considering the danger of a ship collision, should have been placed long ago.
I may be missing the dolphins, but even if they were there, they weren't designed for the larger ships that serviced Baltimore. Time will tell how this all works out, but it's looking to me like some negligence will surface, and will be blamed on anyone but the officials that could have made a difference, but didn't want to spend the money, or were hoping nothing would happen while they were in charge.
I probably need to clarify about what a protection dolphin is. The local large bridges have them at each corner of the main supports to act as fender to prevent a ship from striking the columns. Each consists of a circular outside wall of sheet pile driven into the channel bed, the inside filled with select fill material and the top capped with concrete. They're substantial, and any ship would be stopped before striking the bridge supports.
