Sydney Harbour Bridge was designed between 1911 and 1916 and the construction project commenced in 1923. Construction continued through the period of the Great Depression and was completed in early 1932 at a cost of £10,057,170/7/9d. The opening ceremony was on March 19, 1932.
The bridge is affectionately known as "the Coathanger" by many Sydneysiders. Its familiar arch, which supports the suspended carriageway, spans 503 m and and rises to 134 m above mean sea level. Enormous hinges support the ends of each arch and allow it to adjust and move with temperature changes.
The bridge has a total weight of 52,800 tonnes and is held together by six million hand-driven rivets. It is the world's largest (but not longest) steel arch bridge.
Sydney Harbour is a drowned river valley, eroded through sediments laid down some 250 million years ago when the Australian landmass formed part of the Gondwana supercontinent. The harbour is 19km long with a surface area of 55km². Its volume approximates 500 gigalitres which, as a conventional unit of measurement for large volumes of water, is known as a sydharb.
Access from the northern side is by the stairs in Broughton St., Milsons Point, not far from Milsons Point train station. From the southern end, access is via sheltered stairs from Cumberland Street in the Sydney Rocks area. There is also access from Circular Quay by taking a lift or stairs up to the Cahill Walk, which runs along the Cahill Expressway.
To log this cache all you need to do is post a photo, taken from the walkway at GZ, of whatever you think is the most impressive sight at the moment of your visit. It could be of yachts or tall ships, architecture, a panorama or a stunning night shot. In your log, explain why you choose the subject and if you've come from far away, write a bit about your journey.
Do not use old photos or photos taken from somewhere else. Obviously, you cannot find a cache before it was published. Sadly, some players don't play fairly, in the spirit of the game, and that insults those who do. Invalid "found" claims have been and will be deleted.
