Dear Mr Lissenburg
SOUND WALL – DINGLEY BYPASS
I refer to your recent correspondence to the Hon Ben Carroll MP, Minister for Roads and Road
Safety, on behalf of Friends of Karkarook Park regarding a sound wall for the Dingley Bypass
at Karkarook Park. Your letter was referred to the Department of Transport (DoT) for
response.
Under DoT’s Traffic Noise Reduction Policy, consideration is given to provide noise mitigating
measures for eligible sections of arterial roads and freeways for noise-sensitive buildings.
As indicated in previous correspondence, parks and open spaces do not fall into this category.
DoT may consider short gaps of open spaces as part of proposals to provide continuous noise
mitigating measures where such gaps are likely to provide sound tunnel effect for abutting
noise-sensitive buildings.
The section of Dingley Bypass abutting Karkarook Park is over 750 metres long and is not
considered to be a short gap between two eligible segments of this road abutting noise sensitive
buildings.
Regarding your suggestion to use any excavated surplus material from Suburban Rail Loop
Project to provide earth mounds along the Dingley Bypass as a noise mitigating measure,
the use and disposal of any surplus material from this project is a matter for the Suburban Rail
Loop Authority to manage.
Notwithstanding the above, there are no plans to consider noise mitigation works as this
section of arterial road is not eligible for consideration under the policy.
I trust this clarifies the matter. Thank you for taking the time to write.
Yours sincerely
