Infrastructure projects are underway in the Northern Territory to upgrade major transport corridors. In Central Arnhem, a $21 million contract was awarded to Allan King and Sons to widen and seal a 14-kilometre stretch of the Central Arnhem Road. This work is part of a larger $350 million upgrade programme aimed at improving safety and connectivity for remote communities and industries.

Simultaneously, in Central Australia, a 27km section of the Plenty Highway has been upgraded to a dual-lane sealed road. This project, part of the $217.5 million Outback Way Corridor Upgrade, included the construction of a concrete causeway, floodways, and culverts to support the mining, agriculture, and tourism sectors.
