The Sturt Highway is an Australian highway in New South Wales, Victoria, and South Australia. It is part of the Auslink National network and is part of the main highway route between Sydney and Adelaide.[1]


The Sturt Highway commences at its junction with the Hume Highway near Gundagai south west of Sydney. The Sturt Highway traverses due west roughly aligned to the Murrumbidgee River passing through the city of Wagga Wagga and the towns Narrandera, Darlington Point, Hay, Balranald, Euston, leaving NSW by crossing the Murray River into Victoria from Buronga to Mildura.

The Highway continues more or less due west through the northwest of Victoria before entering South Australia. This section of road was built in 1927 as part of the Murray Valley Road to provide a shorter, and all-weather, road connection between Mildura and Renmark.[2] This section of highway does not pass through many small towns and has not needed significant work to bypass them. This route was not popular with locals when it was built, as it is about ten miles north of an older road with rural service towns along it.[3]

In South Australia, the Sturt Highway passes Renmark, Monash, Barmera, Waikerie, Blanchetown, Nuriootpa and Gawler.

In Victoria and South Australia the highway carries the National Highway number A20, while in New South Wales it is route A20. The route changes to the M20 at Gawler and continues from Gawler Bypass Road south towards the A1 along the Northern Expressway.[4]


South Australia[edit]

None of the Sturt Highway was constructed as dual-carriageway, however work was recently completed to upgrade the highway to freeway standards between the Gawler Bypass and Greenock in the Barossa Valley. The 4 stages of this project are now completed, with the project being completed under budget, and an additional extension being completed in 2010.[5]

The Northern Expressway was built at the south-western end of the Sturt Highway, virtually extending it by 22 km from Gawler southwest to meet Port Wakefield Road (National Route A1) at Waterloo Corner as part of an AusLink/South Australian Government project to build a new dual-carriageway/freeway standard road as part of the North-South Corridor project. This will provide better access for road transport to Port Adelaide and the industrial areas west and northwest of the city.[6] Now completed this has essentially made the Sturt Highway dual-carriageway/freeway standard between Adelaide and the Barossa Valley.

Other projects in South Australia include: a number of overtaking lanes have also been added in recent years to help make it safer with the high volume of traffic.[7] Major 'S'-bend curves near Waikerie have been realigned, and further upgrades to the road are planned up to 2009.[8]


There is also the proposed Mildura Truck Bypass, to be funded by Auslink 2.[9]


The Sturt Highway is named after Charles Sturt, who explored south western New South Wales, the Murrumbidgee and Murray rivers and also parts of the deserts of central Australia in the 1820s and 1830s. The highway crosses the Murrumbidgee at Balranald having followed that river for much of the route from the Hume Highway, and crosses the Murray a total of four times:

  • At Mildura over a high arched bridge
  • At Paringa (near Renmark) over a lift-span bridge which used to have a railway through the middle as well as the road carriageway on each side
  • At Kingston over a high bridge from an embankment on the right bank to the cliffs on the left bank
  • At Blanchetown over another high bridge to cliffs on the right bank.
