The Bridge's construction work demanded a level of skill and precision never before attempted in Australia. And workers laboured without safety nets or safety equipment, often in high-wind conditions, 110 metres above the water. Tragically, sixteen people died during the Bridge's construction.
About 1,500 people worked on the Bridge during each year of its construction. Over the ten years of construction, the number of workers has been estimated to be as high as 4,000. These figures do not include the many thousands of others who laboured at its quarries, built its steel sections, or laid its asphalt roadway.
During its construction, the Bridge was often referred to as the Iron Lung, because so many families depended on the work it generated for survival.
