​Pinjarra Williams Road Improvement

We are continuing works along Pinjarra Williams Road, which provides a key link between the Wheatbelt and the coast. This includes mines around Boddington requiring access to the ports of Fremantle and Bunbury.

Scope of works

The existing two lane road has a narrow seal width, narrow gravel shoulders and steep batters. To improve safety and reduce the risk of serious crashes, the road needs to be widened. It is planned to undertake works in a series of stages over several years to address these concerns by:

  • Widening the existing road pavement and constructing sealed shoulders
  • Improving safety of road verges by flattening slopes and removing roadside hazards

In addition, the works will support economic growth by enabling the effective movement of goods to support industry in the region.

Works east of Dwellingup, which included widening the road pavement, drainage culverts and bitumen sealing, are anticipated to be completed by the end of June 2019. Works will also include an improvement to the recovery zone width.

Works west of Dwellingup were completed in early 2018 and included adding a passing lane westbound and improving the recovery zone widths.


The referral for the upgrade of Pinjarra Williams Road has been published on the Department of Environment and Energy website for public comment.
