This viaduct is located at the back of Bicentennial Park, in the inner west suburb of Annandale. The viaduct was built in 1922 to carry the freight railway line between the Darling Harbour and Rozelle Goods Yards. It now carries the Metro Light Rail line, a tram between Central railway station and Lilyfield. The writing on the brick wall is not graffiti but a dog memorial wall. The dogs are commemorated with photographs, names and quotes at a place where dogs and their owners congregate.
