Great Northern Highway - Koodaideri Bridge

We are constructing and realigning 3.6 km of highway near Auski roadhouse to improve safety. Construction is due to finish in September 2020.
Great Northern Highway - <em>Koodaideri Bridge</em>


Funded by Rio Tinto Iron Ore, we are managing the construction of Koodaderi Bridge. This project 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. 

Works include:

  • Construction of a bridge over the proposed Rio Tinto Iron Ore Koodaideri Rail line
  • Construction and realignment of 3.6 km of Great Northern Highway
  • A new intersection at the Rio Tinto mine access road

The work will be undertaken by a Joint Venture between ACCIONA Geotech and Clough Projects (ACJV) at a cost of $23.5 million. 

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.
