Your tour of Sydney's sightseeing attractions would not be complete without visiting the remarkable Sydney Harbour Bridge, which is affectionately referred to by locals as the 'Coathanger'. This bridge dates to 1932 and is considered to be amongst the largest and most prominent bridges with a steel arch structure on the globe. This bridge enables people as well as goods to be transported daily so that it may be considered to be the city's lifeline. You will find that it is possible to walk or even cycle through this massive structure, but for a truly memorable experience, you will have the opportunity to join a BridgeClimb and ascend to the bridge's summit.
