National Highway Upgrade Programme Projects on the Great Northern Highway

Funding Program:National Highway Upgrade Program
Transport Mode:Road
Expected Start/Finish:Mid 2016 - Mid 2017
Estimated Project Cost:$40,250,000
Australian Government Contribution:$32,200,000

Project Description

In Western Australia, the National Highway Upgrade Program projects are focussed on the Great Northern Highway to support existing freight-based infrastructure investment. The projects are:

  • New Norcia Bypass; and
  • Kumarina (North and South), Karalundi and Munarra Floodways

The New Norcia Bypass involved construction of a 5.6 kilometre long sealed bypass of historic New Norcia with a nine metre wide seal, including tie-in works at either end. In addition, a new 80-metre long, nine-metre wide, bridge was constructed at Moore River East. A scenic lookout was incorporated into the design as an opportunity for tourists to view the town and surrounding landscape.

The Floodways project upgraded four floodways, one located at Karalundi, two at Kumarina (north and south), and one at Munarra in the Mid West - Gascoyne region of the state.


The projects contributed to the productivity of the Great Northern Highway by providing a safer operational environment for 53.5 metre long road trains. In particular, the New Norcia Bypass will contribute to enabling road trains to travel further south (closer to Perth), providing signifiicant efficiencies for the freight sector.


The Australian Government is contributing $32.2 million towards the $40.25 million program.


Construction on New Norcia Bypass commenced in May 2016 and was completed by July 2017.

Construction on Floodways commenced in April 2016 and was completed in February 2017.
