Old Mendooran Road Intersection Project

An independent road safety audit (RSA) has been conducted in the vicinity of the Old Mendooran Road Boothenba Road intersection and is now available to view below.

Dubbo Regional Council (DRC) engaged WaySafe, an independent and fully accredited road safety auditor following a Council resolution to commence the process to close the notorious section of Old Mendooran Road between Boothenba Road and the Golden Highway. The two resolutions of Council are as follows:

  1. That Council commence the process to close the section of Old Mendooran Road between Boothenba Road and the Golden Highway.
  2. That the alignment of the Boothenba Road and Old Mendooran Road intersection be redesigned to ensure the northern leg of Old Mendooran Road intersects Boothenba Road at 90°.

The RSA report concerning the Old Mendooran Road and Boothenba Road intersection and the adjacent level crossing identified two intolerable levels of risk which are as follows.

  1. The angle that Old Mendooran Road intersects both Boothenba Road and the level crossing is too acute, it being impossible for the driver of a heavy vehicle, and difficult for the driver of a light vehicle, to sight to the left along Boothenba Rd, and similarly along the railway line. This is exacerbated by sun glare, roadside vegetation, and a similar distraction for drivers eastbound on Boothenba Road.
  2. The look-through affect for southbound drivers on Old Mendooran Road on approach to Boothenba Road. The level crossing appears more centrally in the driver’s field of view and may distract from the Give Way control at Boothenba Road.


As part of the RSA findings, three options were presented including their associated risk level. These three options are provided below. The RSA report also assessed the road safety risk options for these three proposed options by assessing five main crash types (four of them globally recognised, with a fifth in Australia also considered important).

  1. Option One. Do nothing.
  2. Option Two. Realign the Old Mendooran Road approaches to Boothenba Road and the level crossing, forming a staggered ‘T’ intersection at Boothenba Road.
  3. Option Three. Realign the northern Old Mendooran Road approach to Boothenba Road, to provide a 90° junction, and close the section of Old Mendooran Road south of Boothenba Road, including the level crossing. This would see Old Mendooran Road terminating at Boothenba Road, traffic heading to/from the Golden Highway using Boothenba Road.

Important Crash Type Option One Option Two Option Three
Head-on Improbable + serious = MEDIUM Improbable + serious = MEDIUM Improbable + serious = MEDIUM
Right angle Probable + serious = INTOLERABLE Occasional + serious = HIGH Improbable + serious = MEDIUM
Run off road, side impact into rigid object Occasional + serious = HIGH Occasional + serious = HIGH Improbable + serious = MEDIUM
Crashes involving vulnerable road users Improbable + serious = MEDIUM Improbable + serious = MEDIUM Improbable + serious = MEDIUM
Rear-end crashes Occasional + serious = HIGH Occasional + serious = HIGH Improbable + serious = MEDIUM

 

In line with the Council resolution in January 2021 and the RSA findings, Council staff will progress with Option Three, which based on the RSA report has the lowest level of risks compared to the other two options, especially Option One, which is the existing road condition. Council staff will now seek conceptual and detailed designs of the new alignment before making applications for external funding to complete the work.

As an interim solution, with grant funding from Transport for NSW (TfNSW), Council recently installed line marking, transverse rumble strips, advanced warning signs and enlarged Give Way signs for southbound approaching traffic on Old Mendooran Road.
