Mackenzie River bridge construction

Climate Resilience was engaged by RedFox Advisory to provide detailed wet weather risk for contract contingency and project delivery planning for the new Mackenzie River crossing in Central Queensland. 

The information was used to demonstrate the need for an accelerated decision on award and on program, to ensure completion prior to the onset of the 2023-24 wet season.

In addition, a hydrological assessment included estimation of a low flow rating curve from height only data, for reconstruction of historical frequency at key levels across the site. Prior studies hadn’t included several occasions where backwater flow from the Dawson River could inundate the site.

The project was opened to the public on 19 November 2023 with no wet weather, or river flow allowance exceedance.
