That is a fair question, and I would guess that there are at least two different issues in play.

The first is that the ship probably has little or no ability to steer until it is moving at a few knots (depending on whether it has thrusters; I suspect not.) Once it was moving down the channel, it could steer (assuming the steering gear worked, of course.)

The second is probably that no-one with the relevant authority realized how vulnerable the bridge was to the much larger ships that have come into service since it was built (yet someone apparently realized that the adjacent power transmission towers needed better protection; sometimes people are not good at connecting the dots.)

Oh I am sure someone connected the dots, just that no politician wants to spend $bil on infrastructure if they won’t take the blame personally for an immense failure like this
