BRISBANE RIVER - STORY BRIDGE
Le Story Bridge est un pont franchissant le fleuve Brisbane dans la ville du même nom au Queensland, en Australie. Il constitue un tronçon de la Bradfield Highway et relie les quartiers de Fortitude Valley et de Kangaroo Point. Avant l'ouverture du pont du port de Sydney en 1932, le gouvernement du Queensland a demandé à John Bradfield de concevoir un nouveau pont à Brisbane. Le pont porte le nom de John Douglas Story.
Histoire
Dans les années 1920, le professeur Roger Hawken de l'Université du Queensland proposa la construction de plusieurs ponts sur le Brisbane pour soulager le trafic sur le pont Victoria et le détourner loin du quartier central des affaires de Brisbane. Le Pont Jolly Guillaume fut le premier des ponts du Plan Hawken à être construit. On avait envisagé d'abord la construction d'un pont transbordeur plus en aval, près de New Farm, mais le manque de fonds en empêcha la construction à cette époque. En 1926, la commission chargée des ponts recommanda le site de Kangaroo Point pour sa construction. Le pont a été construit sur des fonds publics pendant la Grande Dépression. Sa construction a commencé le 24 mai 1935, avec la première pelletée de terre par le Premier ministre du Queensland, William Forgan Smith. Jusqu'à son achèvement, il fut connu comme le Pont du Jubilé en l'honneur du roi George V. Il a été inauguré le 6 juillet 1940 par Sir Leslie Orme Wilson, Gouverneur du Queensland et a pris le nom de John Douglas Story.
La conception du pont a été fondée en grande partie sur celui du pont Jacques-Cartier à Montréal, terminé en 1930.
Le Brisbane est un fleuve australien situé dans le sud-est du Queensland et qui traverse la capitale de l'état, Brisbane. Il se jette dans l'océan Pacifique au niveau de la baie Moreton. Longueur : 344 km.

The Story Bridge is a steel cantilever bridge spanning the Brisbane River that carries vehicular, bicycle and pedestrian traffic between the northern and the southern suburbs of Brisbane, Queensland, Australia. It is the longest cantilever bridge in Australia.
The bridge is part of Bradfield Highway (15) and connects Fortitude Valley to Kangaroo Point. It is named for John Douglas Story.
History
Planning
A bridge downstream of the Victoria Bridge was part of a larger plan, devised by Professor Roger Hawken of the University of Queensland in the 1920s, for a series of bridges over the Brisbane River to alleviate congestion on Victoria Bridge and to divert traffic away from the Brisbane central business district. The William Jolly Bridge was the first of the Hawken Plan bridges to be constructed. Lack of funds precluded the construction of the downstream bridge at that time. Initially plans called for a transporter bridge further downstream near New Farm.
In 1926 Kangaroo Point was recommended by the Brisbane City Council's Cross River Commission. Subsequently the bridge was constructed as a public works program during the Great Depression. The cost was to be no more than pounds 1.6 million.
Construction
Before the opening of the Sydney Harbour Bridge in 1932 the Government of Queensland asked John Bradfield to design a new bridge in Brisbane.
The Queensland Government appointed John Bradfield on 15 December 1933 as consulting engineer to the Bureau of Industry who were in charge of the construction of the bridge. In June 1934 Bradfield's recommendation of a steel cantilever bridge was approved. The design for the bridge was based heavily on that of the Jacques Cartier Bridge in Montreal, completed in 1930. On 30 April 1935 a consortium of two Queensland companies, Evans Deakin and Hornibrook Constructions, won the tender with a bid of pounds 1,150,000.
Construction on the bridge began on 24 May 1935, with the first sod being turned by the then Premier of Queensland, William Forgan Smith. Components for the bridge were fabricated in a purpose-built factory at Rocklea. Work sometimes continued 24 hours per day. The bridge has only one pier on the northern bank but two piers on the lower southern bank, one to bear the weight (the main pier) and, further to the south, one to prevent the bridge from twisting (the anchor pier). There was no need for an anchor pier on the northern bank as the bridge was anchored into schist cliff face. The major challenge in constructing the bridge was the southern foundations that went 40 metres below ground level. It was not possible to excavate to that level as water from the level would rapidly seep in. So a pneumatic caisson technique had to be used. As men were working under pressures of up to 4 times normal air pressure, a decompression period of almost 2 hours was needed at the end of each shift to avoid the bends. An on-site air lock hospital successfully treated the 65 cases of the bends that occurred. On 28 October 1939 the gap between the two sides was closed. A concrete decking was then laid, covered by a Trinidad pitch topping. The bridge was painted and sodium lighting was installed. The bridge approaches were also prepared.
Naming
Until it was completed the bridge was known as the Jubilee Bridge in honour of King George V. It was opened on 6 July 1940 by Sir Leslie Orme Wilson, Governor of Queensland and named for John Douglas Story, a senior and influential public servant who had advocated strongly for the bridge's construction.
The Brisbane River is the longest river in south east Queensland, Australia, and flows through the city of Brisbane, before emptying into Moreton Bay. John Oxley was the first European to explore the river who named it after the Governor of New South Wales, Thomas Brisbane in 1823. The penal colony of Moreton Bay later adopted the same name.
Early travellers along the waterway admired the natural beauty, abundant fish and rich vegetation along its banks. From 1862 the Brisbane River has been dredged for navigation purposes. The river served as an important carriageway between Brisbane and Ipswich before a railway linking the towns was built in 1875. By the late 1920s, water quality in the river had significantly deteriorated. The river contains excess nutrients, hydrocarbons, pesticides, bacteria and is murky.
The river travels 344 km (214 mi) from Mount Stanley. The river is dammed by the Wivenhoe Dam, forming Lake Wivenhoe, the main water supply for Brisbane. The waterway is a habitat for the rare Queensland lungfish, Brisbane River cod and bull sharks. The largest ship built on the river was the Robert Miller. The 66,000 tonne vessel became un-moored in the 1974 Brisbane flood. While not the highest experienced along the river since European settlement, this flood was the most damaging. Major floods also occurred in January 2011 and multiple times during 1893.
Extensive port facilities have been constructed on the Fisherman Islands, now known as the Port of Brisbane. There are 16 major bridges that cross the river. The Clem Jones Tunnel, opened in 2010, is the river's first underground crossing for road transport. The CityCat ferry service collects and delivers passengers along the inner-city reaches of the river.
