The Arnhem Highway is the major land transport route between the Stuart Highway and Kakadu National Park. In addition, the Arnhem Highway services the towns and communities of Humpty Doo, Marrakai, Corroboree, Jabiru and Arnhem Land.
The project upgraded the Arnhem Highway to improve flood immunity at the Adelaide River floodplain including:
- construction of approximately 6.6 kilometres of new road alignment on the existing road corridor, between chainages 30.2 and 36.8km, to a finished road level of approximately 4 metres above the floodplain, including a series of multi-span bridge structures along the length of the floodplain; and
- ground improvements and drainage works between chainages 25.1 and 27.9km at Beatrice Hill.
This project will improve road reliability for road users between the Stuart Highway and Mount Bundy.
The project will provide the following benefits:
- improved flood immunity at the Adelaide River floodplain
- increased route reliability and accessibility on the Stuart Highway
- reduced duration and frequency of road closures, through improved pavement strength and flood immunity
The Australian Government has committed up to $62.30 million towards this $77.88 million project.
Construction works commenced in September 2019 and completed in April 2022.
