Wide centrelines

Wide centrelines provide greater separation between traffic traveling in different directions, giving drivers and riders more room to recover if they make a mistake.

Flexible median safety barriers

Flexible median safety barriers help prevent head-on crashes as they are designed to flex when struck, slowing your vehicle and absorbing the impact of the crash.

Improvements to intersections

Intersection upgrades, such as traffic lights and roundabouts, make it safer for people to turn on and off the state highway at key locations.

  • Traffic lights help people who are walking, cycling or scooting to cross the road by providing dedicated crossing facilities.
  • Roundabouts can reduce the number of people killed or seriously injured by typically at least 60%, because they manage both vehicle speeds and crash angles.


‘Jug handle’ turnaround bays give people a safe place to turn around without crossing two lanes of traffic.

Left-in/left-out highway access

Restricting some side road entry and exits to left-turning traffic movements, either as a result of median barrier past entrances or new road layouts, means that people won’t cross oncoming traffic on busy highway stretches.

High performance road markings

High-performance road markings help drivers to stay in their lanes, especially on foggy mornings, at night or during wet weather.


Speed management is a proven, effective way to save lives and prevent debilitating injuries. Safer speeds make a substantial difference to creating safe and sustainable communities.
