Emergency bridging strategy
Main Roads WA, as the lead State road authority, has a responsibility under State emergency management arrangements for the restoration of the road network, including the clean-up and reconstruction of bridge assets during recovery operations. It was identified that there were limited emergency bridging options in the State that would be readily available in the event that a bridge was damaged or destroyed during an incident. In 2012, Main Roads WA established a team to develop a strategy to address these deficiencies. The strategy included the refurbishment of a Bailey bridging system owned by Main Roads WA and the supplementation of this with a larger span system. The strategy also included training of Main Roads WA staff in the use of these systems and the production of contingency plans for bridges where the use of the emergency bridging systems was not feasible. This paper outlines the result of the work carried out including: the emergency bridging options assessed; the condition assessment and refurbishment of the Bailey bridging system; the acquisition and utilisation of a Mabey Compact 200 bridging system; emergency bridge storage arrangements and training of staff; and the development of other contingency arrangements including contingency plans.
