We are progressing a project to upgrade a small section of the Bussell Highway, north of the Cowaramup townsite to improve safety for road users who are currently exposed to roadside hazards.
The upgrade will increase the road width, providing two 3.5 m lanes with 1.5 m to 2 m sealed shoulders on each side of the existing road. The sealed shoulders will also provide safer on-road cycling.
Several upgrades have been successfully completed across the South West region which involved constructing sealed shoulders to improve road environments similar to this one. This is the last section of Bussell Highway between Busselton and Augusta to have 1.5 m to 2 m sealed shoulders provided.
- Provide sealed shoulders on Bussell Highway north of Cowaramup between Treeton Road and Peake Street
- Provide a dedicated right hand turn from Bussell Highway into Treeton Road
- Install a 1.5 to 2 metre sealed shoulder along this section of Bussell Highway
Construction was due to commence in February 2020, however due to a number of drainage design complications and service impacts which have not been satisfactorily resolved, the project has been postponed for a further 12 months.
We have been working with a Community Reference Group since November 2018 to discuss the project and seek input into the design. The group has met three times and members have provided valuable local knowledge, with agreed outcomes including:
- Crash frequency has diminished at Cowaramup in recent years and the community is keen to see this continue.
- Avoid construction works during the busy summer tourist season (i.e. after January and before Easter).
- The tree canopy is very important to the local community. Efforts to minimise the loss of trees will be considered as a part of this upgrade.
- Improving sightlines at the Treeton Road intersection (note: the intersection required changes due to a large sub-division approval progressing on nearby land).
- Extension of the footpath near the doctor's surgery to Noble Grapes if possible.
- To achieve clear sightlines for safety, prune trees in the first instance, with removal of trees to be considered only if necessary.
Given the environmental impact, a formal assessment was not required, with the project approved through Main Roads' Corporate environmental approval process.
Flora and fauna surveys have been undertaken; some trees will need to be cleared but we have minimised the project footprint using steeper batters (the slope alongside the road), with barriers to be installed in some locations as a result.
- Improve safety to reduce likelihood and severity of accidents
- Safe, consistent and comfortable driving environment
- Improved right turn access into Treeton Road
