Not sure... even with an infinite budget, you need time to build your repair solutions. It's possible that for no amount of money can you repair it before it suffers complete collapse without doing risky things that may cause loss of life.

Yup, as the classic saying goes "nine women can't make a baby in one month". There's a minimum time for things even without budget constraints.

Speaking with absolutely no expertise in the matter, I would guess it’s on the verge of collapse due to lack of maintenance or fatal design flaw. It’s probably no longer a matter of fixing more like a total rebuild would be required?

The article also says the NSF has been looking to divest since 2006 in favor of other projects and had a signed agreement to transfer operations to UCF. It's not simply a matter of whether or not it's still useful, but whether it's worth the cost relative to other facilities.
