Digging a bypass is not a days problem, that's a years problem. Everything about this problem is massive.

The shipping lane of the Suez canal is 20 m deep and 77 m wide. The maximum ship length is 400 m, so the turning radius required to get into the bypass is literally miles long.

It would be a lot shorter to "just" dig a canal in front of the ship and park it in there forever, but would still probably take too long.
