The arched span of the Harbour Bridge has the length of 503 meters, the steel arch weighs 39,000 tons, it rises to 134 metros above the sea level, while its height can increase by approximately 180 mm on hot days, due to the expansion of heated metal.

Before the construction of the Harbour Bridge, the area of the city on the left Bank of the river Paramata in its mouth was almost isolated from the city center.

The plan to build a bridge between Davis point and Wilson point of Sydney arose in the mid-nineteenth century. In the next five decades, 24 project of bridge structures and one tunnel project were offered. However, in 1904, they all were rejected. An Australian, John Job Crewe Bradfield, the chief engineer of the Department of public works, engaged in the development of this problem. He gave the preliminary recommendations, on the basis of which specifications were prepared for the International competition of arch bridges with granite coast supports of 1922. The project of the London engineer sir Ralph Freeman of the “Dorman Long” won that competition. The construction under the guidance of Bradfield began in 1926 and ended six years later. The Harbour Bridge was opened in 1932 and by the time of its completion cost $ 20 million. Today drivers going to the southern part of Sydney, pay $ 2 for travel, covering the cost of the bridge maintaining.
