But why is it so expensive?

It requires a tall 500m viaduct which has to cross various obstacles,
rebuilding another mile and a half of track and building two new tube
stations, which go for £10-20m each.

Presumably they're so cheap only because they're *not* tube stations?
Real "tube" (ie, deep-level underground) stations would, I have thought,
cost rather more than £20m each. I assume these new Met stations will
be fairly cheap and cheerful suburban stations, not much fancier than on
the DLR. Of course, they will have to have lifts, level platforms, etc,
to comply with modern statndards.
