No, but it is worth considering what might be possible for a malicious actor in the near future, considering how disastrous this single collision is (which could have been significantly worse in lives lost had it been in the middle of the day).
As it turns out had this happened in the middle of the day we might have been able to avoid all of the casualties. The harbor pilot managed to call shore early enough to have the bridge closed before the ship hit, so the only casualties were an extremely unlucky pothole crew who didn't get the warning in time.
The bridge closure was so fast because there were already police on the bridge for traffic control around the repair crew.
Had it happened during the day, police may not have made it to the entrances in time. Or, if during rush hour, there may not have been time for the bridge to clear even if the entrances were closed.
