​​​​Great Northern Highway - Koodaideri Bridge​

  • Construction and realignment of 3.6 km of highway near Auski roadhouse.
  • Work is expected to be completed in June this year.
  • Improve safety for road users by eliminating the road/rail conflict.


Funded by Rio Tinto Iron Ore and managed by us, the bridge will improve safety and efficiency for the 721 vehicles per day that use this section of Great Northern Highway, 5 km north of Nanutarra Munjina Road intersection. 

The work will be undertaken by a Joint Venture between ACCIONA Geotech and Clough Projects (ACJV) at a cost of $23 million. 

The works also include the construction and realignment of 3.6 kilometres of Great Northern Highway and a new intersection at the Rio Tinto mine access road. 

There will be minimal impact to road users for the majority of the project, as the new bridge will be constructed off the existing alignment. ​

Road users can expect some minor disruptions during the construction of the tie-ins.​
