The Swing (Latrobe) Bridge, built in 1883 by the Victorian government, was the first movable bridge built in Victoria. Designed by John Grainger (the father of famous Australian pianist and composer Percy Grainger) this bridge opened by pivoting horizontally on a set of central piers. The bridge keeper would be summoned, day or night, to open the bridge by the whistle of ships travelling along the Latrobe River.
When the bridge was built, the ships could only go as far as McArdell's Gap, leaving a distance of one mile to the town. This prompted the building of a canal enabling shipping to travel right into town so that the load could be transferred to train at the nearby railway station.
The Sale Canal was built in three stages, beginning in 1886. Much of the work was done by hand, with pick and shovel. Technology did however come to the rescue eventually, involving the use of Chesney's patent automatic earth scoop and William Forbes' traction engine. 1890 became the year of the birth of the Port of Sale.
