dismount. At the same time the NSW Government announced plans to upgrade the southern ramp at a projected cost of 20 million. Both projects are expected to be completed by late 2020. Access to the cycleway on the southern side is via the northern end of the Kent Street cycleway and/or Upper Fort Street in The Rocks. 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. In 1958, tram services across the bridge were withdrawn and the tracks they had used were removed and replaced by two extra road lanes; these lanes are now the leftmost southbound lanes on the bridge and are still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 a terminus at the underground Wynyard railway station is still visible at the southern end of the main walkway under lanes 7 and 8, although around 1964, the former tram tunnels and station were converted for use as a carpark for the Menzies Hotel and as public parking. One of the tunnels was converted for use as a storage facility after reportedly being used by the NSW police as a pistol firing range. Maintenance 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. The most noticeable maintenance work on the bridge involves painting. The steelwork of the bridge that needs to be painted is a combined , the equivalent of sixty football fields. Each coat on the bridge requires some of paint. A special fast-drying paint is used, so that any paint drops have dried before reaching the vehicles or bridge surface. One notable identity from previous bridge-painting crews is Australian comedian and actor Paul Hogan, who worked as a bridge rigger before rising to media fame in the 1970s. 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 of steel below the deck. Workers operated from self-contained platforms below the deck, with each platform having an air extraction
