Duncan Road is a generally northeast-southwest former highway in the northeast of Western Australia and northwest of Northern Territory which links the Victoria Highway with Halls Creek. The highway is approximately 443 kilometres (275 mi) in length, is confusingly designated as National Route 80 from Nicholson to Halls
Creek and snakes its way through the Western Australia / Northern Territory borders numerous times from Victoria Highway to Buntine Highway in a north-south direction.
It then heads westwards towards Halls Creek, and since the change of National Route 80 heading north to Timber Creek from its original alignment westwards, which has been replaced as National Route 96, National Route 80 has been retained in the West Australian section from Nicholson to Halls Creek.
The highway was decommissioned in July 1976. There are no facilities or fuel centres for the length of the 443 kilometre road.
