Sydney Harbour Bridge and its great steel arch

Sydney Harbour Bridge carries road, rail and foot traffic across Sydney Harbour in Australia, its vast steel arch framing the city and waterfront skyline.

Few structures define Sydney as clearly as the great steel arch that carries road, rail and foot traffic across the harbour between the central city and the North Shore. Sydney Harbour Bridge opened in 1932 as a single-span steel arch linking the central business district with suburbs to the north, and its sweeping curve has become one of the most recognisable pieces of infrastructure in Australia. Built as a steel through-arch bridge, it rises high above the water and sits close to Sydney Opera House, creating a paired landmark at the entrance to the city’s inner harbour.

A steel arch binding two shores

Sydney Harbour Bridge is a steel through-arch bridge crossing Sydney Harbour, also known as Port Jackson, between the central business district and the North Shore.steel-arch bridge across Sydney Harbour The arch spans about 503 m (1,650 ft), making it one of the longest steel-arch spans of its type, and the total length of the bridge, including its approaches, reaches around 1,149 m (3,770 ft).total length 1,149 m From the water to the top of the arch is about 134 m (440 ft), a height that gives the structure prominence on the harbour skyline and provides clearance for shipping below.height of top of arch 134 metres

The bridge deck is broad enough to carry multiple transport routes side by side. Along its width, Sydney Harbour Bridge accommodates railway tracks, a multi-lane roadway, a pedestrian walkway and a cycleway, all sharing the same steel structure across the harbour.railroad tracks, a highway, and two pedestrian walkways The deck itself is carried by hangers rising from the arch and supported on massive concrete abutments at either end, faced in granite and flanked by pylons that stand high above the roadway.granite facing used on pylons & piers The result is a single broad crossing in steel and stone that joins the city centre to the northern shore in one continuous span.

Construction and engineering in the early twentieth century

Plans for a major bridge across Sydney Harbour were discussed for more than a century before construction began, but the project finally moved ahead in the early twentieth century. Work on the bridge started in the 1920s and continued for almost a decade, with the steel arch built out from both shores until the two halves met high above the water.construction was started at the same time on both sides The bridge was officially opened to traffic on 19 March 1932, an event marked by a large civic ceremony and formal ribbon-cutting by the New South Wales premier Jack Lang.formally opened on 19 March 1932 by New South Wales Labor Premier Jack Lang

The structure is made from tens of thousands of tonnes of steel, held together by millions of rivets driven by hand over the course of the project.total weight of steelwork 52,800 tonnes As a steel through-arch, Sydney Harbour Bridge was among the largest of its type when completed, with a main span of 503 m and a width that placed it among the broadest long-span bridges in the world.span of 1,650 feet and 160-foot width The approaches and arch together required extensive foundations and supporting structures around the harbour foreshore, using large volumes of concrete and excavated rock to anchor the steelwork securely on both sides.rock excavated for foundations

Crossing the harbour: traffic, views and the city around

Sydney Harbour Bridge serves as a major transport link between the central business district and the northern suburbs of Sydney, carrying rail services, motor vehicles, cyclists and pedestrians across the harbour in one movement.primary transportation link between Sydney and its suburbs on the northern side From the deck, views open out towards Sydney Opera House, Circular Quay, the inner harbour and the residential districts lining the shoreline. The pedestrian walkway on the eastern side and the cycleway on the western side provide linear routes along the bridge, with the steel framework rising overhead and the harbour spreading out below.pedestrian walkway on the eastern side of the bridge and a cycleway on the western side

At either end of the arch, pylons faced in granite rise above the road level and frame the bridge, giving it a sense of mass and monumentality besides its purely structural elements.granite facing used on pylons & piers Below, the harbour narrows where the bridge crosses, bringing ferries, private vessels and harbour traffic close to the steelwork and its foundations. In combination with Sydney Opera House nearby, the bridge’s arch has become an integral part of the city’s waterside silhouette, visible from many viewpoints along the shoreline and from the surrounding hills.

Visiting Sydney Harbour Bridge: what travellers from Western Europe should know

• Sydney Harbour Bridge stands over Sydney Harbour between the central business district and the North Shore in Sydney, Australia, with access from both shores by city streets and public transport.
• The pedestrian walkway on the bridge involves a sustained, gently rising path above road level, while approaches on both sides include stairways and long ramps.
• The bridge crosses a working harbour with exposed positions along the deck and elevated walkways, so conditions on the span can feel more open than in the streets below.
• English is the official language in Australia and the currency is the Australian dollar.
