This view of the south western pylon of the Sydney Harbour Bridge at Dawes Point is from a ferry on Sydney Harbour. The pylons are 90 metres above the water level and this perspective gives an idea of how big they actually are. The four pylons and surrounds are made of concrete that is covered by grey granite, quarried near the south coast town of Moruya. The pylons were placed on each corner of the bridge, mainly for aesthetic reasons. The Sydney Harbour Bridge design had to be functional and pleasing to the eye.
