Harwood Bridge, Road bridge in Northern Rivers, Australia

Harwood Bridge is a steel structure that spans the Clarence River in northern Australia. It is made up of several large truss sections and smaller support spans that work together to cross the waterway.

The structure was completed in 1966 and replaced several ferry services that had previously transported people across the river. With its opening, an era of ferry travel on an important state road connection came to an end.

The bridge is the last of a standard steel truss design built by the Department of Main Roads in the 1950s and 1960s, following earlier examples at Hexham (1952), Karuah (1957) and Kempsey (1959). Its vertical-lift truss span once opened for river vessels, an operation now rarely performed.

Since December 2019 the old bridge no longer carries the Pacific Highway; through traffic uses the four-lane concrete bridge 20 metres to the east. The Harwood Bridge is kept for access to Harwood Island, and a grade-separated pedestrian footpath and cycleway runs along it. The vertical-lift span now opens only infrequently for river vessels.

Although a new concrete bridge was built in 2019, this older structure continues to be actively used. It remains an important access point for people and vehicles reaching Harwood Island.
