Tramway Lift Bridge over Maroochy River  The Tramway Lift Bridge over Maroochy River is a heritage-listed railway bridge at Store Road, Nambour, Sunshine Coast Region, Queensland, Australia. It was built in 1921. It was added to the Queensland Heritage Register on 7 February 2005. The Moreton Central Sugar Mill opened for crushing in 1897. The lift bridge was part of the Moreton Central Sugar Mill Cane Tramway that connected the mill with cane farms, which developed over many years and was in use until late 2003. It was a key factor in the success of the mill and the development of Nambour. Extending the tramway network proved expensive due the nature of the terrain and there were consequent difficulties with the supply of cane to the mill, though by 1905, when the first locomotive, a Krauss 0-6-0 tank locomotive, was purchased, there were of permanent tramline in use. In 1911 a branch line was constructed to the Maroochy River and although the eastern section of the tramway network continued to be extended, lines on the western side were sold to Maroochy Shire in 1914. Two short sections of line on the north side were laid, but a shortage of steel and labour during and after WWI delayed further work. Much of the line was temporary, being laid down for the crushing season. In 1917 a lift up bridge was constructed over Petrie Creek. In 1920, the mill board sought permission from the state government to bridge the Maroochy River and this was granted on 10 May 1920. The new bridge was also a lift bridge and was completed by August 1921. The lift mechanism was necessary as the bridge carried tramline, which had to be level with the land on either side of the river. This made the bridge too low to allow boats to use the waterway. This problem had been addressed since the early nineteenth century by providing bridges with a moveable section. Moveable bridges fall into three types; the bascule bridge, in which two sections hinge upwards, the swing bridge in which a span rotates away from the river, and the lift bridge. In this type, the moveable span is located between two towers and can be raised vertically by means of a system of cable, pulleys and counterweights. The span remains horizontal when lifted, so that river traffic can pass beneath. In larger bridges, engines control the span's movement, though the Maroochy bridge is hand operated. Lift bridges generally are now an uncommon type and this is believed to be the only remaining example of a tramway bridge with a lift span in Queensland.
