Proposal and construction

The idea for the Sydney Harbour Bridge was proposed as early as 1815, when Francis Greenway, an English architect, suggested the construction of a bridge over the harbour. However, it wasn’t until the early 20th century that the idea gained serious momentum.

In 1914, the New South Wales government appointed engineer Dr. John Bradfield to develop a plan for the bridge. Construction finally began in 1924, with the excavation of the foundations.

Timeline and cost

Building the Sydney Harbour Bridge was a monumental task that took several years to complete. Over 2,000 men worked tirelessly for eight long years to bring the vision to life. The bridge’s construction cost a total of £4.2 million, a substantial sum at the time.

The team used an impressive 53,000 tonnes of steel and an incredible six million hand-driven rivets to assemble the bridge’s structural components.

Architectural features

The Sydney Harbour Bridge boasts several remarkable architectural features that contribute to its iconic status. The most significant feature is its distinctive arch design, which stretches 503 meters (1,650 feet) across the harbor.

This design was chosen as it allows for ships to pass beneath the bridge without obstruction. Additionally, the bridge features four granite pylons, which not only provide aesthetic appeal but also add structural strength and stability to the overall design.

Materials used

To ensure the strength and durability of the bridge, a significant amount of high-quality materials were utilized in its construction. For the main structural components, 53,000 tonnes of steel were employed, ensuring the bridge could withstand the immense weight and forces it would experience throughout its lifetime.

The bridge’s deck, made from concrete and steel, provides a stable and secure roadway for vehicles and pedestrians alike.

Opening and significance


The Sydney Harbour Bridge was officially opened to the public on March 19, 1932. The opening ceremony was a momentous occasion, with thousands of people gathering to witness the historic event.

Captain de Groot incident

However, the inauguration of the Sydney Harbour Bridge was not without its quirks. One particularly memorable moment occurred when Captain Francis de Groot, a member of the right-wing New Guard movement, rode on horseback and dramatically slashed the ribbon with his sword before the Premier had the chance to do so.

Although de Groot’s actions were quickly overshadowed and he was removed from the scene, the incident became part of Australian folklore, adding an amusing twist to the bridge’s opening ceremony.
