The state government has announced it would be spending another $50 million in upgrading and maintenance of narrow roads, in the south-west.
Roads minister Luke Donnellan said at least 40 kilometres of arterial roads, that were too narrow for two-way traffic, would be upgraded.
The initial list included Myamyn-Macarthur Road and Foxhow Road, Hamilton, and the Hopkins and Glenelg Highways.
