An 11-kilometre section of highway will be widened to 11 metres between Kojonup and Balgarup Road, including two, 2 metre sealed shoulders.

Project Update

Stage 1 pre-construction works have been completed and included clearing, earthworks and drainage improvements.

Stage 2 began in April 2020. Works will include road construction, safety barrier installation and pavement sealing.


To undertake these works, roadside vegetation on both sides of the highway was cleared however, the design has sought to minimise clearing where possible to 5.5 ha, with the majority considered to be in a degraded condition.

Our initial submission to the Australian Government’s Department of the Environment and Energy determined the proposed works to be a controlled action, due to potential impacts to threatened species and communities listed under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act).

In accordance with section 95A(3) of the EPBC Act, Preliminary Documentation related to the proposal was available for viewing and comment. One submission was received and a response finalised.
