As Leg I use to detonate two bombs.
However, could the canal still be used even if it had survive almost intact is a good question.
Then, what kind of ship will be able to travel through it?
I have not found any clear element but I just found this website (very interesting from what I read in French):

As I read one of the document (from 1953) it quickly became obvious that the canal need quite some level of care and that raise many questions. With the Twilight war the ability to exploit it correctly would probably have disappeared and even if the canal still existed, most ship might not be able to sail through it anymore.
Something to think about (a question to ask also about the Panama canal which, I think, is even more complex).
