The program involved upgrading Great Northern Highway between Muchea and Bindi Bindi in Western Australia’s wheatbelt. Brierty's work included reconstruction and widening, realignment of substandard sections, construction of new passing lanes, intersection upgrades and improvements to roadside amenities including:

  • Upgrading the Great Northern Highway, Brand Highway, Muchea East Road intersection to improve safety and cater for the anticipated increase in traffic and vehicle size after the new Livestock Centre established on Muchea East Road opens;
  • Improving traffic flows for vehicles entering and exiting the Chittering Roadhouse through the addition of turning pockets and an acceleration lane. This site will then be able to be a significant refuelling point for road trains;
  • Increasing road seal width in upgrade areas to meet current and future traffic requirements;
  • Lowering selected hill crests to increase length of vision and improve safety;
  • Realigning sections and adding passing lanes to reduce travel time and improve safety;
  • Upgrading selected side road intersections and driveway locations to improve visibility and safety;
  • Improving road reserve drainage;
  • Minimising the extent of vegetation clearing and re-establishing vegetation to offset losses; and
  • Installing and relocating services to accommodate roadworks as required

Upgrade works have greatly improved the safety and efficiency of the Highway as a major goods transport and tourist route.
