The main span of the bridge was 1100 feet. MV Dali is approx 160 feet wide, and IRCPS ('COLREGs') Rule 9 states a vessel proceeding along the course of a narrow channel or fairway is obliged to keep "as near to the outer limit of the channel or fairway which lies on her starboard side as is safe and practicable.", so it would be normal practice under a bridge span wide enough for two vessels to pass, to aim for a point that's considerably off-center.
The vessel would have been carrying considerable way, and in water much shallower than the beam, would require at least six ships lengths to stop from typical manoeuvring speeds, assuming full astern was available, and there was enough lateral searoom to accommodate the severe slew to one side that is typical of a single screw vessel going hard astern. If the engine failed, low speed steering would be compromised by the lack of forced water flow over the rudder.
Re: WatchfulEye's video link: The observed thick smoke from the funnel implies the engines were rapidly commanded to full speed, and no pilot or watch officer in their right mind would go full ahead towards a near hazard in restricted waters. Its likely that the slew into the bridge pier was mostly due to going full astern with insufficient distance to stop. Dammed if you do, dammed if you don't.
