Opened in Sydney, Australia in 1932 after being built by 1400 men over 8 years, this bridge has a staggering 6 million hand driven rivets. It's the world's largest steel arched bridge and the first 3 coats took 272,000 litres of paint ! And you can now legally climb up and over it. However, I just wanted to take the more unconventional photographs of this icon of Sydney, linking north and south over the bay, And by the way, the top of the arch rises and falls by 18cm depending on the temperature.
