The Sydney Harbour Bridge, the world’s largest steel arch bridge, is an architectural landmark that spans one of mankind’s finest natural harbors.
It was opened on March 19th 1932 and it was affectionately known as the ‘Coathanger’ since then becasue of its shape. The bridge is made of steel and has 6 million hand-driven rivets. The surface area that needs painting is equal to about 60 sports fields’ surface area.
To absorb the expansion caused by the hot Sydney sun, the Bridge has enormous hinges. You’ll see them at the foot of the pylons on either side of the bridge.
The southern end of the bridge is in the area of The Rocks at Dawes Point, and the northern end is in the lower North Shore area at Milsons Point.
The bridge has road, rail, cycling and pedestrian traffic and it is central in celebrations, succh as Olympics or New Year’s Eve, when it is lit with lights.
In last several years it has become popular with climbers, there are few tour companies providing organized climbing on top of the bridge to enjoy the view.
