Frequently asked questions

About the project

What is the Cairns Western Arterial Road, Redlynch Connector Road to Captain Cook Highway, duplication planning project?

The Department of Transport and Main Roads (TMR) is undertaking a $300 million project to duplicate Cairns Western Arterial Road (CWAR), between Redlynch Connector Road and Captain Cook Highway, to provide a four-lane dual carriageway.

The project includes the duplication of the rail overpass at Redlynch and the Kamerunga Bridge over Barron River.

Project timeline

The planning was finalised in November 2021. Detailed design for the entire project will start in early 2022.

TMR will accelerate detailed design for the section of CWAR, between Lake Placid Road and Captain Cook Highway (Stage 1), to allow construction on this section to start in late 2022, weather and construction conditions permitting.

Detailed design for the section between Redlynch Connector Road and Harley Street (Stage 2) will also start in 2022. However, due to compressible soils in this location it will be necessary to perform preloading before construction of this section can begin in 2023.

Detailed design for the final stage between Harley Street and Lake Placid Road (Stage 3), including a new bridge over the Barron River will also start in 2022, however construction of this stage cannot commence until all land requirements have been finalised.

The works will be staged to help in minimising impacts to the travelling public during construction. 

Why aren't grade separated intersections included?

Traffic modelling and economic analysis has shown that grade separation is not warranted or economically viable in the short to medium-term.

The location of the corridor within and beside the Barron Delta floodplain also impacts the viability of grade separated options, particularly between Captain Cook Highway and Lake Placid Road.

Flood immunity

The project will maintain existing flood immunity levels along the corridor.

Bicycle riders

On-road cycle lanes and a shared path with safe crossing points will be provided along the length of the corridor as part of the project. This dedicated pathway will provide improved access to local active transport networks for commuters, recreational cyclists and pedestrians. 

Why are signalised intersections being considered?

Around 22,000 vehicles per day travel on CWAR between Captain Cook Highway and Redlynch Connector Road.

Signalised intersections are required to safely control vehicle movements on high volume roads such as CWAR.

The traffic signals will be coordinated to improve overall link efficiency. The optimisation of the intersections will consider all movements including the side streets.

Project impacts


Road traffic noise is managed in accordance with TMR's Transport Noise Management Code of Practice.  As part of the project a noise modelling assessment will be undertaken.

TMR is mindful of the impacts of construction noise on residents and will do everything reasonably practicable to minimise noise. Noise mitigation measures will be implemented as part of the project to manage and mitigate possible impacts to neighboring residents and property owners.


TMR is committed to the conservation and protection of native fauna and flora as it plans, constructs and maintains the road network. 

Before construction can occur, TMR undertakes environmental assessments of the area to develop management practices to minimise any potential impact on the environment.  

Indigenous and cultural heritage impacts

TMR recognises the significance of different cultures and the importance of protecting Indigenous, historical, shared and natural heritage from impacts caused by road construction. 

TMR (and its contractors) will comply with the cultural heritage duty of care, to ensure there is minimal impact on the cultural heritage of the area, including no harm to Indigenous cultural heritage.

Property values

If concerned, property owners are encouraged to seek professional advice from a licensed valuer or real estate professional.
