Buckingham Bridge, Brookton Highway
264. Hon ALISON XAMON to the minister representing the Minister for Transport:
I refer to the temporary replacement of Buckingham Bridge on Brookton Highway crossing Canning River.
(1) What remediation measures will the minister undertake to correct the heavy siltation occurring at the bridge?
(2) Was the temporary bridge designed and intended to cope with the increased river flow as a result of the winter rainfall?
(3) What modelling of potential stream flows through the bridge was used when designing the temporary bridge?
Hon SIMON O’BRIEN replied:
I thank the honourable member for some notice of this question. I will be brief.
(1) Minor siltation took place on 28 February prior to the completion of the protective works. None has taken place since that time.
(2) Yes.
(3) Standard waterways analysis using data for the catchment area was provided by the Water Corporation.
