George Chaffey Bridge, Toll bridge in Mildura, Australia.

George Chaffey Bridge is a prestressed concrete road bridge carrying the Sturt Highway across the Murray River between Buronga, New South Wales, and Mildura, Victoria. Its main crossing is 331 metres long and 9.8 metres wide over nine spans, built by the Department of Main Roads. The Victorian approach runs 500 metres and includes an 80.4-metre floodway bridge; the New South Wales approach is 1.3 kilometres long with three floodway bridges.

The first Mildura Bridge opened on 22 October 1927, designed for road and rail though tracks were never laid; its lift span and two truss spans now sit in the Mildura Marina. The current bridge, named after engineer George Chaffey, opened on 12 March 1985, funded by the Australian Bicentennial Road Development Programme at a cost of $14 million.

The bridge takes its name from the Canadian engineer George Chaffey, who brought irrigation techniques to the region and transformed it into an agricultural zone. His legacy remains visible in how the area developed around water management and farming.

The George Chaffey Bridge carries the Sturt Highway across the Murray River between Buronga, New South Wales, and Mildura, Victoria, and is free to cross. The main span is 331 metres long and 9.8 metres wide, with a 1.3-kilometre New South Wales approach that includes three floodway bridges and a 500-metre Victorian approach with a six-span floodway bridge.

The old Mildura Bridge, opened in 1927, was built to carry both road and rail traffic, but tracks were never laid. Two of its truss spans and its lift span now stand in the Mildura Marina, where they can be seen today.
