Coolawanyah Road and De Witt Road Intersection upgrade

Project overview

The Coolawanyah Road and De Witt Road Intersection Upgrade involves widening the intersection, resurfacing the road, upgrading culverts and installing additional streetlights to improve visibility and safety. The works will address issues identified in previous Road Safety Audits, including limited space for heavy vehicles, faded line markings and inadequate lighting. Updates to traffic islands and line markings will also be undertaken in line with audit recommendations.

Located at the entrance to the Karratha Industrial Estate (KIE), this intersection provides critical access to major businesses in the area and forms part of the RAV 10 Network used by heavy vehicles.

Construction commenced in January 2025, to enhance safety, functionality and access for local businesses and the wider community. Access to businesses will be maintained throughout the works, with detour routes in place via Mooligun Road and Orkney Road during all necessary road closures.

This upgrade is partially funded by the Australian Government through the Department of Infrastructure, Transport, Regional Development and Communications Sport and the Arts. This project represents a key initiative that will contribute to the continued growth and long-term success of the KIE.
