Kamilaroi Highway safety upgrade - Baan Baa to Turrawan

Kamilaroi Highway Safety Upgrade Baan Baa to Turrawan

Following a Route Safety Review of the Kamilaroi Highway, the NSW Government is funding $26.4 million to boost safety on a 17km stretch between Baan Baa and Turrawan under the Safer Roads Program. Between July 2012 and October 2019, there were 18 crashes recorded, resulting in four fatal crashes, seven serious injury and four moderate injury crashes. A high proportion of these crashes (7) involved vehicles crossing the centre line of the road; recorded as either run off road to the right, or head-on crashes. These alarming numbers triggered significant investment under the Saving Lives on Country Roads program to implement treatments that will reduce the incidence and severity of cross centreline crashes in this location.

The Kamilaroi Highway safety upgrade from Baan Baa to Turrawan will be built in four stages.

Project information

The NSW Government has developed the Saving Lives on Country Roads program to help address the disproportionate number of fatalities on country roads by delivering a number of safety improvements for high risk country roads.

In 2014, Transport for NSW, in collaboration with Centre for Road Safety, completed a Route Safety Review of the Kamilaroi Highway. This review identified the need to review the road network infrastructure and enhance road user behaviour campaigns, especially those targeting driver behaviour, speeding and fatigue between Baan Baa and Turrawan.

The crash history for Baan Baa to Turrawan features a high incidence of cross centre line and run off road into an object crashes, so the NSW Government has funded this important safety project to increase the separation of oncoming vehicles, alert drivers when they leave a lane and provide a more forgiving road environment for when people make mistakes.

Safety treatment works recommended and approved for installation include lifesaving flexible barriers, wide centre lines, audio tactile line marking and other safety devices to help prevent run off road and head on crashes.

As a result of an extensive community consultation process, it was identified that there is a need for the inclusion of overtaking lanes to compensate for lack of overtaking opportunities. Dual overtaking lanes have now been incorporated into the final design and are planned for installation during section two.

Following consultation with the freight industry it was also noted that this section of the Kamilaroi Highway is a common thoroughfare for Over Size Over Mass (OSOM) vehicles. Because of this, we have incorporated a 2.5m sealed shoulder into the design to allow vehicles carrying wide and heavy loads to pull over which will be constructed as part of stage 2.

Other safety measures incorporated into the project include:

  • wide centreline and flexible centre wire rope barrier to reduce the likelihood of head on crashes
  • designated offline school bus turning bay near the Turrawan Road intersection to improve safety for school children and other travellers
  • addition of dual overtaking lanes
  • 5m wide sealed shoulder providing more room for vehicles to recover whilst remaining on a sealed surface
  • rumble strips on centre and outside lines to reduce the likelihood of head on crashes and run off road crashes
  • widened clear zone on roadside to improve visibility and reduce run off road into an object crashes
  • raised retroflective pavement markers to improve delineation

The Kamilaroi Safety Upgrade will be carried out in 4 sections:

  • section 1: Upgrade of 4km stretch south east of Turrawan Road
  • section 2: Incorporation of overtaking lanes towards Baan Baa
  • section 3: Upgrade of road from overtaking lanes north to Section 1 works near Turrawan Road
  • section 4: Upgrade of road south of the overtaking lanes to Baan Baa

Section one of the project is nearing completion. Current works include:

  • culvert extensions and road widening
  • roadside vegetation removal to provide clear zones for improved vehicle recovery
  • installation of a designated offline school bus stop and turning bay near the Turrawan Road intersection to improve safety for school children and other travellers
  • Continue the development of Section 4 at the Baan Baa end.
  • Review some of the major box culverts to see if the preferred treatment can be retrofitted over the existing structures.
  • Undertake early works in Section 2 where the overtaking lanes will be installed.
  • Install the center wire rope barrier and edge barriers where applicable in section 1.
