[1] 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.

In 1920, the mill board sought permission from the state government to bridge the Maroochy River and this was granted on 10 May 1920.

[1] 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 problem had been addressed since the early nineteenth century by providing bridges with a moveable section.

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.

In 1956 land at the River Bridge depot was purchased from the Maroochy Co-Operative Society Limited and the store buildings on it sold for removal.

In 1961 diesel locomotives were purchased which necessitated strengthening bridges and laying heavier rail along the tramways.

[1] The Tramway Lift Bridge over Maroochy River was listed on the Queensland Heritage Register on 7 February 2005 having satisfied the following criteria.

It was a key factor in the development of Nambour and the Maroochy Shire and important in the growth of the sugar industry in Queensland.
