Rosa Brook Road changes ahead | Perimeter Road Project

Main Roads WA has issued their latest update for the ongoing Margaret River Perimeter Road Project, with a notice to residents and road users of changes to the Rosa Brook Road/Bussell Highway access point.

As part of the project works, Rosa Brook Road will be severed on the western side of the existing Margaret River Perimeter Road intersection.

From mid-January, traffic heading west on Rosa Brook Road from Rosa Brook or Nannup will no longer have access to Bussell Highway along Rosa Brook Road.

Traffic heading east on Rosa Brook Road from Bussell Highway will no longer have access to Rosa Brook or Nannup.

The new route linking Bussell Highway and Rosa Brook Road (east) will be via Margaret River Perimeter Road Stage 1.

Local residents can still access Rosa Brook Road from Bussell Highway up to the severance point at the western side of the existing Margaret River Perimeter Road intersection.

Detour signs and speed restrictions will be in place, with Variable Message Signs to be installed on Bussell Highway providing advanced warning of the new routes to road users.

Ultimately, Rosa Brook Road will only be linked to the Margaret River Perimeter Road from the east.

Rosa Brook Road (west) will have a cul-de- sac located to the east of Darch Road.

The western portion of Rosa Brook Road from Bussell Highway - near Yahava Koffeeworks - to the west of the Perimeter Road will continue to provide access to local residents and businesses.

Main Roads Delivery Manager John Szeliga said early consideration was given to a ‘staggered T junction’ at Rosa Brook Road that would have allowed access across the perimeter road.

This option was reviewed and found not to meet the required standards and Safe Systems criteria,” he said.

“John Archibald Drive will be built as part of Stage 2 of the project, providing a linkage to the Perimeter Road from the town site, and will service suburban traffic from the central residential areas in Margaret River.

“We sincerely thank [residents] for their ongoing patience and cooperation and welcome any queries about the project and new road routes.”
