Description

The Sydney Harbour Bridge is a powerful symbol of the city, connecting its northern and southern shores while exemplifying engineering excellence. Completed in nine years and opened on January 19, 1932, the bridge was designed for a future that Sydney’s then-small population could hardly foresee. Today, it accommodates an average of 160,000 vehicles daily, far exceeding the 11,000 it handled at opening, demonstrating the foresight of its creators.

This iconic structure features a massive two 28-panel through-arch design made of 52,000 tonnes of steel, secured by six million rivets. The pylons rise 89 meters high and are anchored by deep bearings, marking a significant engineering achievement recognized as both a National Engineering Landmark and an International Historic Civil Engineering Landmark. During its construction, photographer Henri Mallard documented the process extensively, creating a silent film that has been preserved with insights from supervising engineer Frank Litchfield. The bridge remains a lasting testament to Sydney’s growth and innovation.
