The Sydney Harbour Bridge is the main crossing of Sydney Harbour carrying rail, vehicular, and pedestrian traffic between the Sydney central business district (CBD) and the North Shore. The dramatic water vista of the bridge together with the nearby Sydney Opera House is an iconic image of both Sydney and Australia. The bridge is colloquially referred to as the Coathanger[1] because of its arch-based design, although this usage is less prevalent than it once was. The 75th anniversary of this iconic bridge was celebrated on March 18, 2007.
The bridge was the city's tallest structure until 1967. According to Guinness World Records, it is the widest long-span bridge in the world and is the largest steel arch bridge with the top of the bridge standing 134 metres above the harbour.[1]

The bridge's two ends are located at Dawes Point (in Sydney's Rocks area) and Milsons Point (in Sydney's lower North Shore area). It carries six lanes of road traffic on its main roadway, two lanes of road traffic (formerly two tram tracks) and a footpath on its eastern side, and two railway tracks and a bicycle path along its western side. The western side being 305mm larger that the east side.
The road across the bridge is known as the Bradfield Highway and is about 2.4 km (1.5 miles) long, making it one of the shortest highways in Australia. (The shortest, also called the Bradfield Highway, is found on the Story Bridge in Brisbane). At 48.8 m (151.3 feet) wide, it is the widest long-span bridge in the world (Guinness World Records, 2004). The bridge deck portion of the highway is 1.15 km (0.71 miles) long. It is concrete and lies on trimmers (beams that run along the length of the bridge). The trimmers themselves rest on steel beams that run along the width of the bridge. The trimmers and beams are visible to boats that pass underneath the bridge.
The arch is composed of two 28-panel arch trusses. Their heights vary from 18 m (55.8 feet) at the center of the arch to 57 m (176.7 feet) (beside the pylons).
The arch span is 509 m (1,559 feet) and the weight of the steel arch is 39,000 tons. The arch's summit is 134 m (415.4 feet) above mean sea level, though it can increase by as much as 180 mm (7 in) on hot days as the result of steel expanding in heat. Two large metal hinges at the base of the bridge accommodate these expansions and contractions and thereby prevent the arch from being damaged. The steel used for the bridge was largely imported. About 79% came from Middlesbrough in the North East of England, the rest was Australian-made. The granite used was quarried in Moruya, New South Wales, and the concrete used was also Australian made.
The total weight of the bridge is 52,800 tonnes, and six million hand-driven rivets hold the bridge together. The rivets were made at the Park Bridge Ironworks in Lancashire England.
The two pairs of pylons at each end are about 89 m (276 feet) high and are made of concrete and granite. Abutments, which support the ends of the bridge, are contained at the base of the pylons. They prevent the bridge from stretching or compressing due to temperature variations. Otherwise, the pylons serve no structural purpose and are primarily to visually balance the bridge itself. They were originally not part of the design but were added later to allay concerns about structural integrity — ironically, as the pylons do not actually touch the bridge (except at road level). Although inserted into the designs for their aesthetic value, all four pylons have now been put to use: a museum and tourist centre with a lookout of the harbour is contained in the southeastern pylon. The southwestern pylon is used by the New South Wales Roads and Traffic Authority (RTA) as a base for their CCTV cameras overlooking the bridge and the roads around that area. The two pylons on the north shore are now venting chimneys for fumes from the Sydney Harbour Tunnel. The RTA maintenance shed for the bridge is contained within the bottom of the southern pylon and the traffic management shed (tow trucks and safety vehicles used on the bridge) is contained in the bottom of the northern pylon.

[edit] Planning
There had been plans to build a bridge as early as 1815, when Francis Greenway proposed that a bridge be built across the harbour. Nothing came of this.
The building of the current bridge can be said to have started in 1890, when a royal commission determined that there was a heavy level of ferry traffic in the Sydney Harbour area, best relieved with the construction of a bridge. Vehicular access to the north shore was undertaken with a series of smaller bridges located further westwards in the harbour, but this was insufficient for the traffic in the Sydney/North Sydney area.
Designs and proposals were requested in 1900, but a formal proposal was not accepted until 1911. In 1912, John Bradfield was appointed chief engineer of the bridge project, which also had to include a railway. After travelling extensively to look at a number of bridges worldwide, he based his idea upon New York's Hell Gate Bridge. He completed a formal design — the now familiar single arch shape — in 1916, but plans to implement the design were postponed until 1922, primarily because of World War I.
In November 1922 the NSW parliament passed laws that allowed the bridge's construction. Construction tenders for the bridge were requested the same year, and the British firm Dorman Long and Co Ltd, Middlesbrough won. To offset concerns about a foreign firm participating in the project, assurances were given by Bradfield that the workforce building the bridge would all be Australians.
The building of the bridge coincided with the construction of a system of underground railways in Sydney's CBD, known today as the City Circle, and the bridge was designed with this in mind. The bridge was designed to carry six lanes of road traffic, flanked by two railway tracks and a footpath on each side. Both sets of rail tracks were linked into the underground Wynyard railway station, on the south side of the bridge, by symmetrical ramps and tunnels. The eastern-side railway tracks were intended for use by a planned rail link to the Northern Beaches; in the interim they were to be used to carry trams from the North Shore into a terminal within Wynyard station.
[edit] Construction
The building of the bridge was under the management of Bradfield. Three other people were involved in the bridge's design and construction: Laurence Ennis, the engineer-in-charge at Dorman Long and Co was the main supervisor (Bradfield visited occasionally throughout the project, and in particular at the many key stages of the project, to inspect progress and make managerial decisions); Edward Judge was Chief Technical Engineer of Dorman Long and later became President of the British Iron and Steel Federation; Sir Ralph Freeman was hired by the company to design the accepted model in further detail. Later a bitter disagreement broke out between Bradfield and Freeman as to who actually designed the bridge. Another name connected with the bridge's design is that of Arthur Plunkett.
Serious initiatives started after the end of World War I. Tenders were called for in 1923 either an arch or a cantilever bridge would meet the requirements. Dr J.J.C. Bradfield was responsible for setting the parameters of the tendering process. He and his staff were to ultimately oversee the entire bridge design and building process. The Bradfield Highway, which is the paved section of the bridge and its approaches, still bears his name to this day.
The tender of Dorman Long and Co. Ltd., of Middlesbrough, England for an arch bridge was accepted. The Dorman Long and Co's Consulting Engineer, Sir Ralph Freeman, carried out the detailed design of the bridge. The design was similar to New York's Hell Gate Bridge built in 1916. The Hell Gate Bridge was a little shorter in span but was much lighter in construction as it only carried four railway tracks.
The construction project itself began in 1923, with the demolition of 800 homes. The owners of these homes received compensation, but their occupants did not.
The first stage of the bridge project was the building of two worksheds at Milson's Point to assist in building the bridge — the light and heavy workshops. Their purpose was to build the bridge's many parts.
The first sod for the bridge was turned that same year. In January 1925, the excavations to build the abutments and approach spans began. In October 1925, the building of the abutments and approach spans themselves began, and these were completed in September 1928. Construction of the bridge itself began in December 1928, with the construction of the bridge parts in the workshops.
Construction of the arch of the bridge began in 1929, with two separate teams building the arch on each side using creeper cranes. The first panel was erected on the southern side in March 1929. The southern end of the bridge was worked on a month ahead of the northern end, in order to detect any errors and to ensure that they did not happen on the northern side.
During construction the two halves of the arch were held up by numerous support cables. Once the arch halves were completed the cables were slowly released to bring the two halves of the arch together. This was finalised on the afternoon of 19 August 1930. Ennis and four associates personally witnessed this whilst standing on top of the bridge. Following a parting that occurred due to the contracting of metal in the evening, the ends were rejoined at 10 pm, and have remained joined since then. The support cables were then surplus to the design and removed. They were subsequently used to provide the support cables for the Walter Taylor Bridge, over the Brisbane River in the western suburbs of Brisbane, Queensland.
The road and the two sets of tram and railway tracks were completed in 1931. Power and telephone lines, and water, gas and drainage pipes were also all added to the bridge in that year. On 19 January 1932, the first test train, a steam locomotive, safely crossed the bridge. About 90 others also crossed the bridge in the months that followed as part of a series of tests to ensure the bridge's safety.
The construction worksheds were demolished after the bridge was completed, and the land that they were on is now occupied by Luna Park and the North Sydney swimming pool.
The standards of industrial safety during construction were poor by today's standards. Sixteen workers died during construction, mainly from falling off the bridge. Several more were injured from unsafe working practices undertaken whilst heating and constructing its rivets, and deafness experienced by many of the workers in later years was blamed on the project.
The total financial cost of the bridge was £10,057,170.7s.9d (double the original quote). This was not paid off in full until 1988.
[edit] Opening of the bridge
The bridge was formally opened on 19 March 1932. Amongst those who attended and gave speeches were the State Governor, Sir Philip Game, the Minister for Public Works, and Ennis. The Premier of NSW, Labor politician Jack Lang, was to open the bridge by cutting a ribbon at its southern end.
However, just as he was about to do so, a man in military uniform moved forward on horseback and slashed the ribbon with a sword, declaring the bridge to be open "in the name of His Majesty the King and the decent and respectable citizens of New South Wales". He was promptly arrested. The ribbon was hurriedly retied and Lang performed the official opening ceremony. After he did so, there was a 21-gun salute and a RAAF flypast.
The intruder was identified as Francis de Groot. He was convicted of offensive behaviour (he was fined £5)after a psychiatric test proved he was sane. De Groot was not a member of the regular Army but his uniform allowed him to blend in with the real cavalry. He was a member of a right-wing paramilitary group called the New Guard, opposed to Lang's leftist policies. This incident was one of several that Lang had with the New Guard in that year.
A similar ribbon-cutting ceremony on the bridge's northern side by North Sydney's mayor, Alderman Primrose, was carried out without incident. It was later discovered that Primrose was also a New Guard member, but his role in and knowledge of the de Groot incident, if any, are unclear.
A message from a primary school in Tottenham, 340 miles (550 km) away in rural NSW, arrived at the bridge on the day and was presented at the opening ceremony. It had been carried all the way from Tottenham to the bridge by relays of school children, with the final relay being run by two children from the nearby Fort Street Boys' and Girls' schools.
Other features of the opening ceremony included a vast display of floats and marching bands — one quite remarkable by Depression standards. The public was allowed to walk on the highway.
There had been numerous preparatory arrangements. On 14 March 1932, three postage stamps were issued to commemorate the imminent opening of the bridge. One of these stamps, with a face value of five shillings, is worth several hundred dollars today.
Several songs were also composed in advance for the occasion. These have now been largely lost or forgotten.
The bridge itself was regarded as a triumph over Depression times, earning the nickname "the Iron Lung", as it kept many Depression-era workers employed.
[edit] Function
[edit] Access
From the Sydney CBD side, motor vehicle access to the bridge is normally via Grosvenor Street, Clarence Street, Kent Street, the Cahill Expressway, or the Western Distributor. Drivers on the northern side will find themselves on the Warringah Freeway, though it is easy to turn off the freeway to drive westwards into North Sydney or eastwards to Neutral Bay and beyond upon arrival on the northern side.
Pedestrian access from the northern side involves climbing an easily-spotted flight of stairs at Milsons Point. Pedestrian access on the southern side is more complicated, but signposts in the Rocks area now direct pedestrians to the long and sheltered flight of stairs that leads to the bridge's southern end. These stairs are located near Gloucester Street and Cumberland Street in the Sydney Rocks area.
The bridge can also be accessed from the south by getting on Cahill Walk, which runs along the Cahill Expressway. Pedestrians can access this walkway from Circular Quay by a flight of stairs, or a lift, alternately it can be accessed from The Botanical Gardens.
The bridge lies between Milsons Point and Wynyard railway stations, located on the north and south shores respectively, with two train lines running along the western side of the bridge. Milson's Point station is part of the North Shore line.
The Bradfield Highway is designated as a Travelling Stock Route which means that it is permissible to herd livestock across the bridge, but between midnight and dawn, and after giving notice of intention to do so. In practice, because of efficient methods of rail and road transport, and the relocation of the abattoirs and markets, such an event has not taken place for about fifty years.
[edit] Tolls
There is currently a toll of $3.00 for traffic headed into the CBD (southbound). No toll is charged for northbound traffic.
There are toll plazas at the northern and southern ends. The eastern-most southbound lanes (which continue over the Cahill Expressway after leaving the bridge) have their tollbooths at the northern end of the bridge, with the remainder being at the southern end of the bridge.
The toll was originally placed on travel across the bridge, in both directions, to recoup the cost of its construction. This cost was recovered in the 1980s, but the toll has been kept (indeed increased) by the State Government's main roads infrastructure department (the RTA) to recoup the costs of the Sydney Harbour Tunnel.
After the decision to build the Sydney Harbour Tunnel was made in the early 1980s, the toll was increased (from 20 cents to $1, then to $1.50, and finally to $2 by the time the Tunnel opened) to pay for its construction. The Tunnel also had an initial toll of $2 southbound. After the increase to $1, the concrete barrier on the Bridge separating the Bradfield Highway from the Cahill Expressway was increased in height, because of the large numbers of drivers crossing it illegally from lane 6 to 7 , in order to avoid the toll. The Toll for all southbound vehicles was increased to $3 in March 2004.
Use of the bridge by bicycle riders (provided that they use the cycleway) and pedestrians is free. Motorcyclists must pay the full-price toll for passenger vehicles. Previous governments had capped this toll at one-quarter of the passenger vehicle cost, or 50 cents.
[edit] Tidal flow
This refers to the arrangements for altering the direction of traffic flow on the bridge, during the morning and evening rush hours. The bridge has a series of overhead gantries which indicate the direction of flow for each traffic lane. The bridge has eight lanes in total, numbered one through eight from west to east. Lanes three, four and five are reversible. One and two always flow north. Six, seven and eight always flow south. The default is four each way. For the morning rush hour, the lane changes on the bridge also require changes to the Warringah Freeway, with its inner western reversible carriageway directing traffic to the bridge lane numbers three and four southbound. It is possible to see odd arrangements of flow during night periods when maintenance occurs, which may involve completely closing some lanes. Normally this is done between midnight and dawn, due to the enormous traffic demands placed on the bridge outside these hours.
A green arrow pointing down to a traffic lane means the lane is open. A flashing red 'X' indicates the lane is closing, but is not yet in use for traffic travelling in the other direction. A red 'X' means the lane is in use for oncoming traffic. The whole arrangement was introduced in the 1990s replacing a slow operation where lane markers were manually moved to mark the center medium.
[edit] Tourism
The South-east pylon for many years operated as lookout and tourist attraction, containing a number of telescopes and antiquated arcade games which operated on pennies, long after that currency had gone out of operation. The couple that ran this tourist venue also kept a number of white cats which gave the interior of the pylon a memorable odour. The pylon has recently been renovated and returned to its tourist function.[2]
Since 1998, BridgeClimb[3] has made it possible for tourists to climb the southern half of the bridge. Tours run throughout the day, from dawn to dusk and are only cancelled for electrical storms or high wind. Night climbs are also available. Groups of climbers are provided with protective clothing appropriate to the prevailing weather conditions and are given an orientation before climbing. During the climb, attendees are secured to the bridge by a wire lifeline. Each climb begins on the eastern side of the bridge and ascends to the top. At the summit, the group crosses to the western side of the arch for the descent. Each climb is a three-and-a-half-hour experience.

In 1958, tram services across the bridge were withdrawn and the tracks they had used were removed and replaced by two extra road lanes; these lanes are now the leftmost southbound lanes on the bridge and are still clearly distinguishable from the other six road lanes. The original ramp that took the trams into their terminus in the underground Wynyard railway station is still visible at the southern end of the main walkway under lanes 7 and 8 although the tunnels have been sealed off. Lanes 7 and 8 now connect the bridge to the elevated Cahill Expressway that carries traffic to the Eastern Distributor. The Bridge originally only had four wider traffic lanes occupying the central space which now has six, as photos taken soon after the opening clearly show. The width of the lanes now is so small that buses passing each other in adjacent lanes do so a few inches apart.
In 1988, work began to build a tunnel to complement the bridge. It was determined that the bridge could no longer support the increased traffic flow of the 1980s. The Sydney Harbour Tunnel was completed in August 1992. It is intended only for use by motor vehicles. Before it was officially opened for use, the tunnel was made open for pedestrian access, with persons on that day able to walk down the tunnel's roadway.
In 2006, the first complete repainting for many years commenced. A reason for the decision was the concern that weight of the many layers of paint acquired over the years might be having a destructive effect on the bridge's structure. Because of the previous regime of continuous maintenance painting with lead-based paint, precautions had to be taken to prevent falling paint from contaminating the harbour. This required that each section being painted be sealed off and blasted to remove old paint, then extracted by vacuum.
Security on the bridge has been introduced, due to the heightened risk of terrorist attack.

Since the opening, the bridge has been the focal point of much tourism and national pride. It has also been the scene of about 40 suicides, many of which took place within months of the bridge's opening, during the Great Depression.
In 1982, the bridge celebrated the 50th anniversary of its opening. Once again, the bridge was closed to vehicles and pedestrians allowed full access for the day. The celebrations were attended by Edward Judge, who represented Dorman Long.
Australia's bicentennial celebrations on 26 January 1988 attracted large crowds in the bridge's vicinity as merrymakers flocked to the foreshores in order to view the events on the Harbour. The highlight was the biggest parade of sail ever held in Sydney, with square-riggers from all over the world, surrounded by hundreds of smaller craft of every description, passing majestically under the Sydney Harbour Bridge. The day's festivities culminated in a fireworks display in which the bridge was the focal point of the finale, with fireworks streaming from the arch and roadway. This was to become the pattern for later firework displays.
During the millennium celebrations in 2000, the Sydney Harbour Bridge was lit up with the word "Eternity", as a tribute to the legacy of Arthur Stace a Sydney artist who for many years inscribed that word on pavements in chalk in beautiful Copperplate writing.
In May 2000 the bridge was closed to vehicular access for a day to allow a special reconciliation march — the "Walk for Reconciliation" — to take place. This was part of a response to an Aboriginal "Stolen Generation" inquiry, which found widespread suffering had taken place amongst Australian Aboriginal children forcibly placed into the care of white parents in a little-publicised state government scheme. A large number of Australians walked the bridge in a symbolic gesture of crossing a divide.
During the Sydney 2000 Olympics in September and October 2000, the bridge was adorned with the Olympic Rings. It was included in the Olympic torch's route to the Olympic stadium. The men's and women's Olympic marathon events likewise included the bridge as part of their route to the Olympic stadium. A massive fireworks display at the end of the closing ceremony ended at the bridge. The East-facing side of the bridge has been used several times since as a framework from which to hang static fireworks, especially during the elaborate New Year's Eve displays.
[edit] 75th Anniversary
In 2007, the 75th anniversary of its opening is being commemorated with an exhibition at the Museum of Sydney, called "Bridging Sydney" [3]. An initiative of the Historic Houses Trust, the exhibition features dramatic photographs and paintings with rare and previously unseen alternative bridge and tunnel proposals, plans and sketches.
On 18 March, 2007, the Sydney Harbour Bridge celebrated its 75th anniversary. The occasion was marked with a ribbon-cutting ceremony by the Governor of New South Wales, Marie Bashir and the Premier of NSW, Morris Iemma. The bridge was subsequently open to the public to walk southbound from Milsons Point or North Sydney. Several major roads, mainly in the CBD were closed for the day. An Aboriginal "smoking" ceremony was held at 7pm.
Approximately 250,000 people (50,000 more than were registered) took part in the event. Bright yellow souvenir caps were distributed to walkers. A series of speakers placed at intervals along the bridge formed a sound installation. Each group of speakers broadcast sound and music from a particular era (eg. King Edward VIII's abdication speech; Gough Whitlam speech at Parliament House in 1975), the overall effect being that the soundscape would "flow" through history as walkers proceeded along the bridge. A light show began after sunset and continued late into the night, where the bridge was bathed in constantly-changing, multi-coloured lighting, designed to highlight structural features of the bridge. In the evening the bright green caps were replaced by orange caps with a small, bright LED attached. The bridge was closed to walkers at about 8:30 PM.
[edit] New Year's "Bridge Effect"
Towards the end of each year since 1998, the Sydney Harbour Bridge has what is referred to coloquially as the "Bridge Effect", in which fireworks and a light display using a framework and rope lighting are used to complement the fireworks on New Years Eve. In the months leading up to December 31 (usually from late October), the scaffolding and framework are clearly visible, as is the outline for the design, which leaves the Sydneysiders speculating as to how the effect is to be realised.

The question mark doubled up as the curved end of the coathanger.

- Prophetic observation of Sydney Cove by Erasmus Darwin, grandfather of Charles Darwin, from his poem 'Visit of Hope to Sydney Cove, near Botany Bay' (1789)
"I open this bridge in the name of His Majesty the King and all the decent citizens of NSW."
- Francis de Groot 'opens' the Sydney Harbour Bridge, (1932). His organisation, the New Guard, had resented the fact that King George V hadn't been asked to open the bridge.
"To get on in Australia, you must make two observations. Say, "You have the most beautiful bridge in the world" and "They tell me you trounced England again in the cricket." The first statement will be a lie. Sydney Bridge [sic] is big, utilitarian and the symbol of Australia, like the Statue of Liberty or the Eiffel Tower. But it is very ugly. No Australian will admit this."
