MOUNTAIN BRIDGE, MIDLANDS ROAD — CLOSURE
Given that Mountain Bridge on the Midlands Road between Dongara and Mingenew has been closed to vehicles greater than 10 tonnes since 7 February this year — (1) Who decided to close Mountain Bridge and when was the minister informed? (2) What alternative routes are available to vehicles greater than 10 tonnes and what arrangements have been made for Transwa bus customers on the Midlands route? (3) When will the bridge be repaired, and is it dependent on a pile driver becoming available? (4) What heritage issues and Indigenous or native title issues need to be resolved before the bridge can be rebuilt? (5) Has the damage to the bridge been caused by trucks transporting iron ore from Morawa to Geraldton? Ms A.J.G. MacTIERNAN

AnswerView source ↗

I thank the member for notice of the question. (1) Main Roads limited the bridge to as-of-right vehicles only following an inspection of the bridge by the Main Roads regional manager on 19 February 2008 due to deterioration of a number of piles. A further restriction to vehicles of greater than 10 tonnes gross mass was imposed on Friday, 29 February following a further inspection. These restrictions will be lifted today as propping works have been carried out by a Main Roads day labour bridge crew to allow the bridge to return to normal service. That is another affirmation of our attempts to rebuild Main Roads’ capacity, which was destroyed under the previous government. (2) The Main Roads regional office has been liaising with transport operators, including the Public Transport Authority, on these matters since the bridge restriction was enacted on 19 February. In addition, a notice has been posted in the local papers. PTA services through Mingenew were rerouted depending on customer needs. (3) The final extent of the repairs will be determined following an inspection that will be undertaken today. I repeat that a temporary device has been put in place, which has enabled us to open it up. (4) Section 18 of the Aboriginal Heritage Act requires that clearances be provided for permanent repair work. We are currently finalising an agreement with the Yamatji Land and Sea Council. We have gained an exemption under section 18 for the temporary works in order to secure the structural integrity of the bridge. (5) The assessment is that the damage is not due to trucks transporting iron ore from Morawa to Geraldton; rather, it is due to general deterioration of the bridge.
