It wasn't a matter of "switch and mate" type construction that could
be easily paved over and forgotten. The Sydney tramways were
controlled for much of their early life by the Railways Department,
and so they built railway points buried in the street. There was a
largish pit under the blades to contain the tie bars etc to joint the
dual blades together and this HAD to be pulled out sooner or later to
enable a good long term road only surface to be created. Take a look
at the pointwork at the Sydney Tramway Museum, it has the big pits.
Even where the straight running track is still under the tar, the
points were always entirely removed.

I don't spend much time in Sydney anymore but about 10 years ago I was up
real early in the morning and was on the top of the ramp on the corner of
the main train station and there was a huge amount of special work visible
in the street in the slanting light. It was quite visible, rivalling the
special work at the Breakfast Creek Bridge in Brisbane which was also very
visible through a thin layer of bitumen 10 years ago.
