Sydney Harbour Bridge

They started building the Mackinac Bridge in 1957. The bridge was finished and allowed traffic to cross it in 1957.

This depends entirely on what defines "biggest".

The Sydney Harbour Bridge is the largest steel arch bridge in the world, though not the longest, with the top of the bridge standing 134 metres above the harbour. At 48.8 m wide, it is the widest bridge in the world (as of 2004).

However, the Hornibrook Highway, which was the first bridge to connect Brisbane with the Redcliffe Peninsula, used to be the longest road bridge in Australia. The 2.8km two-lane Hornibrook Highway was opened on 4 October 1935, and featured a single central arch where the channel of the river runs, allowing for fishing craft to pass underneath. Deterioration of the bridge through the years necessitated the building of a new bridge, and a replacement three lane bridge, the Houghton Highway, was opened in 1979. A second bridge running oarallel to the Houghton, the Ted Smout Bridge, was completed in 2010. The Hornibrook Highway has now been dismantled.

The Sydney Harbour Bridge is in Sydney, Australia.

Usually concrete supports are built IN the water, either resting on the sea floor or actually dug down into it. Then there are a lot of different methods for connecting the land on Side A with the first in-water support, then the second in-water support, then finally to the land on Side B. The part of the bridge that has air underneath it and no support directly underneath is called the "span".

The total length of the Sydney Harbour Bridge including approach spans is 1149 metres and its arch span is 503 metres. The top of the arch is 134 metres above sea level.

It is the widest single-span bridge in the world.

It also is designed in a unique pattern that is not used anywhere else in the world.

Yes. The Sydney Harbour Bridge is commonly nicknamed The Coat-hanger because of its distinctive arch style.

Over 800 homes as well as the Dawes Point Battery. These were demolished to make way for the Bradfield Highway that connects to the Sydney Harbour Bridge.

Arch bridges are one of the world's most ancient bridge forms. The arch gives the bridge its essential strength. Between the engineer of the Sydney Harbour bridge, Ralph Freeman, and the designer, JCC Bradfield, this was seen as the best option for the purpose.

Freeman felt that since the purpose of the bridge was to cross a wide harbour which often saw some fairly wild weather, the arch shape would be the most stable.

Originally, the bridge's designer, JCC Bradfield, proposed a suspension bridge, then a cantilever bridge, which was the first proposal accepted. After that, Bradfield turned his sights towards an arch bridge, after travelling overseas and seeing the developments in light steel which made a steel arch bridge such a possibility.

Yes there were many attempted suicides on the bridge within the first 6 months of opening and a few did survive the jump.

The most famous of falls from the Sydney Harbour Bridge was a worker during the construction, Vincent Kelly. He fell 50m from the road deck landed feet first only breaking three ribs.

The Sydney Harbour Bridge is seen as an iconic symbol of Australia. Its distinctive coathanger shape is instantly recognisable, and is possibly one of the things tourists expect to see. In this way, it probably helps contribute to the tourism industry. It is one of Australia's most recognisable landmarks.

More significantly, the Sydney Harbour Bridge connected the northern and southern sides of the Harbour. This contributed considerably to the urban and residential growth and development of Sydney in the post World War II years. In turn, this boosted the city's economic development.

Credit for the construction of the Sydney Harbour Bridge largely belongs to engineer Dr J. C. C. Bradfield (who also oversaw the construction of Brisbane's Story Bridge), while the firm that built the bridge was Dorman Long and Co Ltd, Middlesbrough, Teesside.

Sir Ralph Freeman, of Freeman Fox & Partners, was the designer of the Sydney Harbour Bridge.

Another civil engineer involved in the Sydney Harbour Bridge project was J. F. Pain, who was awarded the Manby Premium for a paper on the Sydney Harbour Bridge. He led a group of about forty engineers working for Freeman on Sydney Harbour bridge.
