North West Coastal Highway and Madigan Road

Road Train Assembly Area

We are constructing a new road train assembly area along the North West Coastal Highway, to allow road trains to break down and assemble safely.
North West Coastal Highway and <em>Madigan Road</em>


We are building a new Road Train Assembly Area (RTAA) on the corner of Madigan Road, adjacent to North West Coastal Highway. 

The RTAA will allow road trains to break down and assemble safely and away from residential buildings. It will also ensure that heavy vehicle operators have an opportunity to manage fatigue issues. The passing lane provides a safe opportunity for overtaking, and addresses traffic congestion on North West Coastal Highway.

As part of this project, we will:

  • Construct the RTAA with 36 triple Road Train breakdown bays and lighting. 
  • Widen Madigan Road to improve access and incorporate drainage improvements
  • Construct an addition 2.1 km overtaking lane on North West Coastal Highway between Karratha and Roebourne.

There will be minimal impact to road users during the construction of the Road Train Assembly Area as work will be undertaken off the existing Madigan Rd alignment. 

Road users can expect some disruptions during the construction of the Overtaking Lane on North West Coastal Highway, with some traffic management in place.
