Barwon Highway
The Barwon Highway is one of the shorter state highways of Queensland, Australia, connecting the Goondiwindi Region and the Shire of Balonne. It starts at the Carnarvon Highway in Nindigully, 44 kilometres south of St George, and travels east for about 155 kilometres until it reaches Goondiwindi, where it terminates at the Leichhardt Highway.
The highway travels north of and roughly parallel to the Barwon River, after which it is named. The river forms part of the border between Queensland and New South Wales.This highway is part of State Route 85, which extends for over from Bribie Island to Nindigully, duplexing with the Brisbane Valley Highway from the D'Aguilar Highway to Esk, the New England Highway from Hampton to Toowoomba, the Gore Highway from Toowoomba to the Leichhardt Highway, and the southern section of the Leichhardt Highway to Goondiwindi.Stock route
Like many Australian roads, the Barwon Highway follows a declared stock route. The road reserve for most stock routes is wider than for other roads. When seen from the air the substantial width of the western end can be clearly seen due to the difference in colour between roadside brigalow scrub and adjacent cropland.Upgrades
Pavement widening
A project to widen sections of pavement on the highway, at a cost of $6.75 million, was expected to complete in June 2022.
