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.[citation needed]
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. In 1958 tram services across the bridge were withdrawn and the tracks replaced by two extra road lanes; these lanes are now the leftmost southbound lanes on the bridge and are still clearly distinguishable from the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. Lanes 7 and 8 now connect the bridge to the elevated Cahill Expressway that carries traffic to the Eastern Distributor.[citation needed]
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 for use only by motor vehicles.[citation needed]
The Bradfield Highway is designated as a Travelling Stock Route which means that it is permissible to herd livestock across the bridge, but only between midnight and dawn, and after giving notice of intention to do so. In practice, owing to the high-density urban nature of modern Sydney, and the relocation of abattoirs and markets, this has not taken place for approximately half a century.[citation needed]
Tidal flow
The bridge is equipped for tidal flow operation, permitting the direction of traffic flow on the bridge to be altered to better suit the morning and evening rush hours' traffic patterns.[36]
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.[citation needed]
The bridge has a series of overhead gantries which indicate the direction of flow for each traffic lane. 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 static red "X" means the lane is in use for oncoming traffic. This arrangement was introduced in the 1990s, replacing a slow operation where lane markers were manually moved to mark the centre median.[citation needed]
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, because of the enormous traffic demands placed on the bridge outside these hours.[citation needed]
Tolls
The vehicular traffic lanes on the bridge are operated as a toll road. As of 27 January 2009 there is a variable tolling system for all vehicles headed into the CBD (southbound). The toll paid is dependent on the time of day in which the vehicle passes through the toll plaza. The toll varies from a minimum value of $2.50 to a maximum value of $4.[37] There is no toll for northbound traffic (though taxis travelling north may charge passengers the toll in anticipation of the toll the taxi must pay on the return journey). There are toll plazas at the northern and southern ends. The two eastern lanes (which continue over the Cahill Expressway at the southern end of the bridge) have their tollbooths at the northern end, while the other southbound lanes (for CBD traffic) are serviced by tollbooths at the southern end of the bridge. There is a bridge-long median strip between lanes 6 and 7 to separate traffic which has already paid the toll (at the northern end) from other southbound traffic (which must pay the toll at the southern end).[citation needed]
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 Roads and Traffic Authority to recoup the costs of the Sydney Harbour Tunnel.[citation needed]
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, to avoid the toll. The toll for all southbound vehicles was increased to $3 in March 2004.[citation needed]
Originally it cost a car or motorcycle six pence to cross, a horse and rider being three pence. Use of the bridge by bicycle riders (provided that they use the cycleway) and by pedestrians is free. Later governments capped the fee for motorcycles at one-quarter of the passenger-vehicle cost, but now it is again the same as the cost for a passenger vehicle.[citation needed]
In July 2008 a new electronic tolling system called e-TAG was introduced. The Sydney Harbour Tunnel was converted to this new tolling system while the Sydney Harbour Bridge itself had several cash lanes. The electronic system as of 12 January 2009 has now replaced all booths with E-tag lanes.[38]
Pedestrians

The pedestrian footway. Side fences were added to prevent people from committing suicide by jumping from the bridge.
The pedestrian-only footway is located on the east side of the bridge. Access from the northern side involves climbing an easily-spotted flight of stairs, located on the east side of the bridge at Broughton St, Kirribilli. 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.[citation needed]
The bridge can also be approached from the south by accessing Cahill Walk, which runs along the Cahill Expressway. Pedestrians can access this walkway from the east end of Circular Quay by a flight of stairs or a lift. Alternatively it can be accessed from the Botanic Gardens.[citation needed]
Cyclists
The bike only cycleway is located on the west side of the bridge. Access from the northern side involves carrying or pushing a bicycle up a staircase, consisting of 55 steps, located on the west side of the bridge at Burton St, Milsons Point. A campaign to eliminate the steps on this popular cycling route to the CBD has been running since at least 2008.[39][40] Cyclist access on the southern side is via the north end of the Kent St. cycleway and/or Upper Fort St.[citation needed]
Rail

The bridge lies between Milsons Point and Wynyard railway stations, located on the north and south shores respectively, with two tracks running along the western side of the bridge. These tracks are part of the North Shore railway line.[citation needed]
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 at 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 converted into a car park and firing range.[citation needed]
Maintenance

Maintenance crew painting the bridge
The Sydney Harbour Bridge requires constant inspections and other maintenance work to keep it safe for the public, and to protect from corrosion. Among the trades employed on the bridge are painters, ironworkers, boilermakers, fitters, electricians, plasterers, carpenters, plumbers, and riggers.[24]
The most noticeable maintenance work on the bridge involves painting. The steelwork of the bridge that needs to be painted is a combined 485,000 m2 (120 acres), the equivalent of sixty football fields. Each coat on the bridge requires some 30,000 l (6,600 imp gal) of paint.[24] A special fast-drying paint is used, so that any paint drops have dried before reaching the vehicles or bridge surface.[16] One notable identity from previous bridge-painting crews is Australian comedian and actor Paul Hogan, who worked as a bridge painter before rising to media fame in the 1970s.[6]
In 2003 the Roads & Traffic Authority began completely repainting the southern approach spans of the bridge. This involved removing the old lead-based paint, and repainting the 90,000 m2 (22 acres) of steel below the deck. Workers operated from self-contained platforms below the deck, with each platform having an air extraction system to filter airborne particles. An abrasive blasting was used, with the lead waste collected and safely removed from the site for disposal.[24]

Between December 2006 and March 2010 the bridge was subject to works designed to ensure its longevity. The work included some strengthening.[41]
Since 2013, two grit-blasting robots specially developed with the University of Technology, Sydney have been employed to help with the paint stripping operation on the bridge.[42] The robots, nicknamed Rosie and Sandy,[43] are intended to reduce workers' potential exposure to dangerous lead paint and asbestos and the blasting equipment which has enough force to cut through clothes and skin.[44]
Tourism

South-east pylon
Even during its construction, the bridge was such a prominent feature of Sydney that it would attract tourist interest. One of the ongoing tourist attractions of the bridge has been the south-east pylon, which is accessed via the pedestrian walkway across the bridge, and then a climb to the top of the pylon of about 200 steps.[14]
Not long after the bridge's opening, commencing in 1934, Archer Whitford first converted this pylon into a tourist destination.[45] He installed a number of attractions, including a café, a camera obscura, an Aboriginal museum, a "Mother's Nook" where visitors could write letters, and a "pashometer". The main attraction was the viewing platform, where "charming attendants" assisted visitors to use the telescopes available,[45] and a copper cladding (still present) over the granite guard rails identified the suburbs and landmarks of Sydney at the time.[46]
The outbreak of World War II in 1939 saw tourist activities on the bridge cease, as the military took over the four pylons and modified them to include parapets and anti-aircraft guns.[47]
In 1948 Yvonne Rentoul opened the "All Australian Exhibition" in the pylon. This contained dioramas, and displays about Australian perspectives on subjects such as farming, sport, transport, mining, and the armed forces. An orientation table was installed at the viewing platform, along with a wall guide and binoculars. The owner kept several white cats in a rooftop cattery, which also served as an attraction, and there was a souvenir shop and postal outlet.[48] Rentoul's lease expired in 1971, and the pylon and its lookout remained closed to the public for over a decade.[49]
The pylon was reopened in 1982, with a new exhibition celebrating the bridge's 50th anniversary.[50] In 1987 a "Bicentennial Exhibition" was opened to mark the 200th anniversary of European settlement in Australia in 1988.[51]
The pylon was closed from April to November 2000 for the Roads & Traffic Authority and BridgeClimb to create a new exhibition called "Proud Arch". The exhibition focussed on Bradfield, and included a glass direction finder on the observation level, and various important heritage items.[52]
The pylon again closed for four weeks in 2003 for the installation of an exhibit called "Dangerous Works", highlighting the dangerous conditions experienced by the original construction workers on the bridge, and two stained glass feature windows in memory of the workers.[53]
BridgeClimb
In 1950s and 1960s there were occasional newspaper reports of climbers who had made illegal arch traversals of the bridge, invariably by night. In 1973 Philippe Petit walked across a wire between the two pylons at the southern end of the Sydney Harbour Bridge. Since 1998, BridgeClimb[54] has made it possible for tourists to legally climb the southern half of the bridge. Tours run throughout the day, from dawn to night, and are only cancelled for electrical storms or high wind.[citation needed]
Groups of climbers are provided with protective clothing appropriate to the prevailing weather conditions, and are given an orientation briefing 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 takes three-and-a-half-hours, including the preparations.[citation needed]
In December 2006, BridgeClimb[54] launched an alternative to climbing the upper arches of the bridge. The Discovery Climb allows climbers to ascend the lower chord of the bridge and view its internal structure. From the apex of the lower chord, climbers ascend a staircase to a platform at the summit.[citation needed]
Celebrations
Since the opening, the bridge has been the focal point of much tourism and national pride.[citation needed]
50th Anniversary celebrations (1982)
In 1982 the bridge celebrated the 50th anniversary of its opening. For the first time since its opening in 1932, the bridge was closed to vehicles, and pedestrians were allowed full access for the day.[11] The celebrations were attended by Edward Judge, who represented Dorman Long.[citation needed]

Bicentennial Australia Day celebrations (1988)
Australia's bicentennial celebrations on 26 January 1988 attracted large crowds in the bridge's vicinity as merrymakers flocked to the foreshores to view the events on the harbour. The highlight was the biggest parade of sail ever held in Sydney, 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.[citation needed]
Sydney New Year's Eve (1993–present)
Main article: Sydney New Year's Eve
The Harbour Bridge is an integral part of the Sydney New Year's Eve celebrations, generally being used in spectacular ways during the fireworks displays at 9:00 P.M. and midnight. In recent times, the bridge has included a ropelight display on a framework in the centre of the eastern arch, which is used to complement the fireworks. As the scaffolding and framework are clearly visible for some weeks before the event, revealing the outline of the design, there is much speculation as to how the effect is to be realised.
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 despite the fact that he was illiterate.[citation needed]
The effects have been as follows:[citation needed]

The numbers for the New Year's Eve countdown also appear on the eastern side of the Bridge pylons.[citation needed]
Walk for Reconciliation (2000)
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 Generations 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. Between 200,000 and 300,000 people were estimated to have walked the bridge in a symbolic gesture of crossing a divide.[55]
Sydney 2000 Olympics
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 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.[citation needed]
Formula One promotion (2005)
In 2005 Mark Webber drove a Williams-BMW Formula One car across the bridge.[56]
75th anniversary (2007)

Walkers with LED caps on the bridge's 75th Anniversary

The commemorative hats given to walkers
In 2007, the 75th anniversary of its opening was commemorated with an exhibition at the Museum of Sydney, called "Bridging Sydney".[57] An initiative of the Historic Houses Trust, the exhibition featured dramatic photographs and paintings with rare and previously unseen alternative bridge and tunnel proposals, plans and sketches.[citation needed]
On 18 March 2007, the Sydney Harbour Bridge celebrated its 75th anniversary. The occasion was marked with a ribbon-cutting ceremony by the governor, Marie Bashir and the premier of New South Wales, Morris Iemma. The bridge was subsequently open to the public to walk southward 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 7 pm.[citation needed]
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 (e.g. King Edward VIII's abdication speech; Gough Whitlam's 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, the bridge being 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 p.m.[citation needed]
Breakfast on the Bridge (2009–10)
On 25 October 2009 turf was laid across the eight lanes of bitumen, and 6,000 people celebrated a picnic on the bridge accompanied by live music.[58] The event was repeated in 2010.[59] Although originally scheduled again in 2011, this event was moved to Bondi Beach due to traffic concerns about the prolonged closing of the bridge.[60][61]
80th anniversary
On 19 March 2012 the 80th anniversary of the Sydney Harbour Bridge was celebrated with a picnic dedicated to the stories of people with personal connections to the bridge.[62] In addition, Google dedicated its Google Doodle on the 19th to the event.[63] The proposal to upgrade the bridge tolling equipment was announced by the NSW Roads Minister Duncan Gay.[64]
Quotations

The "International Historic Civil Engineering Landmark" plaque presented to Sydney Harbour Bridge by the American Society of Civil Engineers in 1988
There the proud arch Colossus like bestride
Yon glittering streams and bound the strafing tide.
—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 "opening" the Sydney Harbour Bridge, (1932). His organisation, the New Guard, had resented the fact that King George V had not been asked to open the bridge.[citation needed]
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.
—James Michener assessing the Sydney Harbour Bridge in his book "Return to Paradise", (1951).
...you can see it from every corner of the city, creeping into frame from the oddest angles, like an uncle who wants to get into every snapshot. From a distance it has a kind of gallant restraint, majestic but not assertive, but up close it is all might. It soars above you, so high that you could pass a ten-storey building beneath it, and looks like the heaviest thing on earth. Everything that is in it – the stone blocks in its four towers, the latticework of girders, the metal plates, the six-million rivets (with heads like halved apples) – is the biggest of its type you have ever seen... This is a great bridge.
—American travel-writer Bill Bryson's impressions of the Sydney Harbour Bridge in his book "Down Under", (2000).[65]
