the modern practice is layers of defense; in addition to building a bridge that doesn't fail at a single point of failure, you also generally design what's around a bridge pier to stop or at least slow down the ship (by, say, running aground onto a bed of rocks around a pier) For a bridge such defenses are called dolphins.

Naval ships do have alternate ways to steer, but that does not mean they have alternate power to the Rudder.
I find it all very odd.

But they will drag it out for sure and cripple the economy up there. Nothing gets done in a hurry these days.

Corps of Engineers, not exactly military.

The complexity of this salvage operation suggests the main shipping channel will be closed for weeks if not months. ...On Monday evening, US Coast Guard Rear Admiral Shannon Gilreath told reporters that salvage operations underneath the water are even more complicated than initially imagined:
"These girders are essentially tangled together, intertwined, making it very difficult to figure out where you need to potentially cut so that we can make that into more manageable sizes to lift them from the water."
At the same press conference, Governor Wes Moore said: "We're talking about something that is almost the size of the Statue of Liberty ... and the scale of this project, to be clear, is enormous. And even the smallest (tasks) are huge."
