Without propulsion and steering, a maneuver the crew is probably trained to use is drop anchors in an attempt to slow the vessel. That does not provide controllable steering, and it is a very inefficient braking system, but it's pretty much the only onboard option remaining.
Downside of that is, the anchors are at the bow, not the stern. So if they drag hard enough or catch on the bottom, the momentum will cause the stern to swing out in some direction to pass the bow which is being restrained, at some degree of inefficiency, by an anchor or anchors, effectively altering the direction of the vessel's course fairly quickly. Kinda like a staked-out running animal hitting the end of its chain.........only on a massively larger scale of energy at work.
The rate of that bridge dropping is more a result of support of its continuous truss being removed, and the expected progressive failure, as it is not capable of self-sustaining support without its engineered ground support.
If it was all ship speed and momentum from beginning to end of collapse, it would be expected that highway bridge would have been forced, dragged, carried, propelled, something, many many yards downstream by high speed impact, rather than doing the nearly vertical drop as the ship ended its low speed movement.

I heard some other news programs and they were talking about, some of people who were starting investigation already wondered why the anchors were never dropped
