Mudies Creek
Project overview
The Australian and New South Wales Governments are jointly investing $133 million in a vital infrastructure upgrade to construct a new road crossing over Mudies Creek at Whittingham, south of Singleton.
The Mudies Creek project will deliver a 28-metre-long bridge designed to withstand a one-in-100-year flood event. This new structure will be built five metres higher than the existing road level, significantly improving travel reliability and safety along the Golden Highway during severe weather and flooding.
Project background
The Golden Highway is a 313-kilometre-long rural highway, mostly with single lanes, connecting the New England Highway at Belford in the Hunter Valley to the Newell Highway at Dubbo via Denman, Merriwa and Dunedoo.
The upgrade at Mudies Creek is part of a package of work being delivered on the Golden Highway, between Whittingham and Dubbo, to improve safety, traffic efficiency, network reliability and freight access.
Major work as part of the Golden Highway package includes intersection improvements, road rebuilding, shoulder widening, overtaking lanes, rest area improvements and flood immunity projects.
The NSW Government is providing $109 million funding, with an additional $24 million funding from the Australian Government, for the work at Mudies Creek.
