Well I never knew they had to rework those cables to remove excess vibes..
The ANZAC Bridge is the longest span cable-stayed bridge in Australia. The bridge is 32.2 metres (106 ft) wide and the main span is 345 metres (1,132 ft) long. The reinforced concrete pylons are 120 metres (390 ft) high and support the deck by two planes of stay cables. Initially the stay cables were plagued by vibrations which have since been resolved by the addition of thin stabilising cables between the stay cables.
