Bradfield was appointed as Chief Engineer for the construction
of the Sydney Harbour Bridge. The four 89 metre high pylons
are made of concrete, faced with granite, quarried near Moruya.
Three ships were specifically built to carry the 18,000 cubic
metres cut, dressed and numbered granite blocks, 300km north
to Sydney. In July 1931 pylon construction advanced rapidly.
As the carpenters completed the scaffold, concreters and masons
set the masonry, then poured the concrete behind. The gangers
built the steelwork in the pylon towers. The day labourers laboriously
cleaned the granite with wire bushes. In January 1932 the masons
set the last stone in the pylons & timber towers supporting
the pylon cranes were removed.
