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, although quarterly flat-fee passes are available which are much cheaper for frequent users. Originally there were six toll booths at the southern end of the bridge, these were replaced by 16 booths in 1950. The toll was charged in both directions until 4 July 1970 when changed to only be applied to southbound traffic. 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. In January 2017 work commenced to remove the southern toll booths. In August 2020, the remaining toll booths at Milsons Point were removed. Pedestrians The pedestrian-only footway is located on the east side of the bridge.

These stairs are located near Gloucester Street and Cumberland Street. 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. Cyclists The bike-only cycleway is located on the western 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 western side of the bridge at Burton Street, Milsons Point. A wide smooth concrete strip in the centre of the stairs permits cycles to be wheeled up and down from the bridge deck whilst the rider is dismounted. A campaign to eliminate the steps on this popular cycling route to the CBD has been running since at least 2008. On 7 December 2016 the NSW Roads Minister Duncan Gay confirmed that the northern stairway would be replaced with a 20 million ramp alleviating the needs for cyclists to
