If it was merely a bridge, it could be rebuilt. The difficulty is Ryde
tunnel, which is almost a quarter of a mile in length and prone to
flooding. That wasn't a great problem in the days of steam, but when the
system was electrified, the only way to avoid constant short circuiting
was to raise the base of the tunnel by about a foot, hence the very
restricted headroom.

You'd think by now they could just install some decent pumps. The
water seepage can't be much worse than what the tube experiences despite
the sea being nearby. Isn't it rumoured that most central london tube
stations would flood within a day if all the pumps were switched off?
