Bussell Highway

Vasse to Margaret River


Our project to upgrade Bussell Highway between Vasse and Margaret River is complete. 

Around 5500 vehicles per day use the highway from Busselton to Margaret River, and this number increases during summer and holiday periods. Works completed on Bussell Highway have reduced the crash rate and improved safety.

Final works were completed in March 2016, and involved widening Bussell Highway from North Jindong Road to Marbellup Road to tie in at Vasse Bypass and included improvements to the intersections at North Jindong Road and Marbellup Road.

Previous works at the intersection of Wildwood Road and Bussell Highway were completed on 17 December 2015 and included:

  • Adding a dedicated right turn pocket on the highway for vehicles (from Busselton) into Wildwood Road;
  • Widening the bridge over the Carbunup River to provide room for the right turn pocket; and
  • Widening the highway on both approaches to the new, wider bridge.
  • Widening the sealed shoulders south of the bridge to 1.5 m.
  • Upgrading the storm water drainage system to divert discharge away from the river into detention ponds.

We met with residents of Carbunup in November 2012 to discuss their concerns with the Wildwood Road intersection. The issues raised resulted in us applying for and receiving funding through the Safer Roads Program to complete the project. We also met on site in August 2015 with Busselton Dunsborough Environment Centre representatives to discuss clearing requirements (limited to the eastern side of the highway) and revegetation program in the area. We thank residents and BDEC for their input into this important project.

Completed works

Bramley Forest Section and North Jindong Road to Carbunup

This section was completed in December 2014 and included:

  • Widening a 1.5 km section from North Jindong Road to Carbunup (north of Carbunup River bridge),
  • Widening works in Bramley Forest Section with a northbound passing lane past Tanah Marah Road intersection over a 2 km section of Bussell Highway, north of Bramley Brook to Burnside Road and
  • A right turn pocket into the Tanah Marah intersection.

The Bramley Forest section involved the acquisition of State Forest and National Park, along with State and Federal environmental approvals, and a commitment to a post-construction re-vegetation program. We sincerely thank local environmental groups for their ongoing involvement in the consultation process around the extensive environmental investigations required to retain environmentally significant vegetation.

These two sections followed on from the completion of the 1.5 km section of Bussell Highway between Bramley Brook and Osmington Road in April 2014, which included widening the highway and providing barrier protection from road side vegetation to reduce the risk of run off road crashes. Improvements to the intersection of Bussell Highway and Osmington Road were made by providing left and right turn pockets into Osmington Road.

Completed works: Chambers Road to Island Brook

This section was completed in 2012/13 and included the excavation of approximately 100,00m3 of material near Yelverton Road to lower the crest and improve sight distance for vehicles turning in and out of Yelverton Road.  The Island Brook Bridge was also widened to accommodate the new road formation.

Preliminary earthworks in the section between Carbunup and Island Brook utilised the material excavated from the Yelverton Road cutting.  This section included extensive realignment to eliminate a number of substandard curves.  Work on this part of the project was completed in February 2013.



We paid particular attention to maintaining and preserving vegetation in the road reserve corridor.  Other sections of the road corridors on Bussell Highway were reserved and roadside areas planted.

We had undertaken extensive environmental investigations and consultation with environmental groups and identified that vegetation in the Bramley Forest was environmentally significant on the western side.  The road improvement included road side barriers to ensure the existing environmentally significant vegetation was retained and greater protection from road side vegetation was provided to the road user.

As mentioned, the Bramley Forest section involved the acquisition of State Forest and National Park, along with the State and Federal environmental approvals, and a commitment to a post-construction re-vegetation program.  We worked closely with the Department of Environment and Regulation to develop an environmental offset for the permitted clearing required as part of this project.



  • Providing breakdown refuge areas and opportunities to safely pass other vehicles by adding overtaking lanes and
    widening the highway.
  • Reducing the number and severity of crashes by widening and realigning some sections of the road to provide a more forgiving road environment for any vehicles straying from the road.
  • Improving access, protection and sight distances for vehicles entering and leaving the mainstream traffic
    through key intersection upgrades.
  • Reducing both travel times for motorists and transport costs.
  • Enhancing industrial, agricultural and tourism opportunities for the South West Region by improving access to the
    Vasse Margaret River area.
  • A revegetation program that will provide greater and longer term environmental benefits to address the short term environmental impacts caused by vegetation clearing.


Community involvement

A Community Liaison Committee of local representatives helped Main Roads progress the plans for the improvements. The Committee has met both prior to, and after phases of development and provided valuable input into proposed designs and coordination of construction work. As a result, the completed works have been implemented in line with the group's recommendations.

We would like to thank community representatives for their involvement in this important regional project, and will continue discussion and consultation for the works planned in the remainder of the Bussell Highway program.
