Market Street. In 1980, most of the eastern abutment was demolished as part of the construction of the Western Distributor. A section connected to the bridge remains, and the isolated easternmost plinth and lamppost can still be seen near the corner of Market Street and Sussex Street. In 1980, the eastern end of the bridge was initially connected via a ramp to the viaduct leading north to King Street, but this was demolished in 1981 when the rest of the viaduct was completed around the southern end of Cockle Bay. Only a narrow pedestrian and cycle path still connects the eastern end of the bridge to the viaduct and to King Street. A separate pedestrian bridge was constructed over the Western Distributor roadway to connect the eastern end of the bridge to Market Street at surface level. Between 1988 and 2013, the bridge carried the elevated Sydney Monorail, which travelled between Darling Harbour and the Sydney central business district. The monorail track rested on a pivot that allowed the track to remain stationary while the bridge swung underneath. The pivot allowed the monorail to continue to cross the bridge even when the bridge was opened. The construction of the monorail led to some changes to the bridge, including the electrification of the previously hand-operated brakes used to control the bridge's swing, and the relocation of the control cab six metres away from the middle of the bridge (so that the control cab would not hit the monorail track when the bridge is open). Upon the closure of the Monorail in June 2013 the hydraulic lifting rams and support infrastructure were removed, and the control cab was relocated to its original position in the middle of the bridge. Heritage listing As at 24 July 2001, Pyrmont Bridge is an item of State heritage significance for its aesthetic, historical and scientific cultural values. An essential link between the city and the inner western suburbs, Pyrmont Bridge is closely associated with the economic and social development of Sydney at the end of the 19th century. Pyrmont Bridge is closely associated with Percy Allen, PWD Engineer-in-Chief of bridge design, who was responsible for the introduction of American timber bridge practice to NSW and designed over 500 bridges in NSW. The quality of the carved stonework of the piers and portals added to the aesthetic appeal of the bridge. At the time of construction the
