Cairns Western Arterial Road, Redlynch Connector Road to Captain Cook Highway duplication planning

Planning and design for the Cairns Western Arterial Road (CWAR) between Redlynch Connector Road and Captain Cook Highway aims to improve the safety and increase capacity of this section of the road.

In June 2019, the Queensland Government announced $12.45 million in funding to undertake planning and design for future upgrades on Cairns Western Arterial Road. 

The project aims to investigate the alignment for duplication of the single-lane section of Cairns Western Arterial Road, assess options and develop a cost estimate, Business Case and detailed design for the most suitable solution. 

Planning will include environmental and cultural heritage investigations, community consultation, traffic analysis, flood and drainage analysis, geotechnical analysis and detailed design.

The Department of Transport and Main Roads recognises the strong interest in this project from local government, residents, commuters, freight operators and tourism operators and will seek input from key stakeholders during the planning phase. This feedback will be used to inform planning and assessment of option.
