Motorists to save 20 minutes travel time on South West trip with new highway nearing completion

Motorists heading to the South West will save nearly 20 minutes travel time with a new highway set to open at the end of the year.

The Bunbury Outer Ring Road, will be named the Wilman Wadandi Highway, after the traditional owners of the land where the new highway is located.

At a cost of $1.4 billion, the 27-kilometre, four-lane highway is the biggest road project ever delivered in the South West.

The announcement of the formal name of the new road comes as the project passes the 86 per cent completion milestone.

The highway connects Forrest Highway to Bussell Highway, bypassing Bunbury, shaving 18 minutes travel time off the commute to and from the South West.

Transport Minister Rita Saffioti said the Wilman Wadandi Highway will make the journey down south more efficient for commuters.

"It will also help to address congestion on local Bunbury roads by removing vehicles that previously used the local road network to reach places like Busselton, Dunsborough and Margaret River," she said.

"The project has delivered a major injection for the local economy by creating thousands of jobs, while more than half a billion dollars has been spent to date with local businesses."
