We've all seen a lot of bridges and it seems as if the ones I've noticed have a wide concrete pier around where the towers go into the water. I had assumed this was to prevent exactly this sort of thing. Maybe container ships have grown to the point that the above water part can hit the tower before the underwater part runs aground.
Going forward, maybe the replacement should be a tunnel, or a bridge such that the towers are located on land or in shallow water, such that a ship will not be able to reach this vulnerable structure under any circumstance.
Added: The span had some bit of pier around it, but the supports are very close to the edge. This was a disaster waiting to happen.
