❓ Mr Marshall asks about the Dawesville deviation project's completion timeline and noise mitigation measures. Mr Cowan, on behalf of the Minister for Transport, provides details on the project timeline, use of noise-reducing asphalt, noise monitoring plans, and potential construction of noise walls if noise levels exceed acceptable limits.

After six years of planning, tenders have been called for the Dawesville deviation. How long will the project take to finish and what precautions are being undertaken to keep down traffic noise for the benefit of local residents? Mr COWAN

I thank the member for some notice of this question. The Minister for Transport has provided the following response. The contract period for the Dawesville deviation is 24 weeks. It is expected that the road construction contractor will commence work in mid October 2000 and the project will be completed and open to traffic in April 2001. The Dawesville deviation will be constructed using open graded asphalt, which is recognised as a lower noise-producing road surface than the standard chip seal surface. In addition, a commitment has been given to undertake annual monitoring of traffic noise from the Dawesville deviation, commencing immediately after the opening of the road. The noise monitoring will be used to calibrate the Main Roads noise prediction model and to assess the longer-term noise reduction effectiveness of open graded asphalt. Should the noise monitoring and subsequent modelling indicate that traffic noise from the deviation exceeds Main Roads’ criteria of 63 decibels - the member for Armadale quite often exceeds that level in this House - noise walls will be constructed at appropriate locations along the road within 12 months of completion of the modelling.
