Captain Cook Highway - Smithfield Bypass Project


Smithfield Bypass Alignment video

The Captain Cook Highway — Smithfield Bypass project will construct a new 3.8km long road between McGregor Road roundabout and the Cairns Western Arterial Road (CWAR) and Captain Cook Highway (CCH) as an alternative route to the Captain Cook Highway.

Construction commenced in December 2018.


Captain Cook Highway between McGregor Road and the intersection of  CWAR / CCH in Smithfield.


Construction is expected to be completed late 2021, weather permitting.


The Smithfield Bypass provides vital infrastructure for the northern beaches of Cairns and meets the strategic transport needs of the area into the future. The new road will deliver a safer, more efficient travel route for motorists and industry along this section of the CCH.
The bypass will improve traffic conditions on the Smithfield road network by addressing congestion on the section of the CCH between McGregor Road and the intersection of CCH and CWAR. In particular the Smithfield and CCH and CWAR roundabouts. Traffic improvements will be achieved by:

  • Upgrade to a four-legged signalised intersection at the existing roundabout at CWAR and CCH. The new intersection will have the capacity to effectively manage increased traffic volumes now and into the future.
  • Removing through traffic from the local road network. This will significantly reduce the volume of traffic using Smithfield roundabout by approximately half the current level. With reduced volume of traffic Smithfield roundabout will once again operate effectively as originally designed. 

All intersections in Smithfield will benefit from the network connectivity as the majority of through traffic on the CCH will be removed from the Smithfield local road network. By connecting the Bypass road to the intersection of CCH and CWAR motorists are given the opportunity to choose to continue along either CCH or CWAR. 


The design and construct contract has been awarded to Highway Construction / Albem Operations Joint Venture (HAJV).


$152 million (Queensland Government).

Captain Cook Highway – Smithfield Bypass Project Preliminary Design

The Smithfield Bypass is being undertaken using a Design and Construct contract. This means that the Department of Transport and Main Roads (TMR) will work closely the contractor to finalise the design and complete construction. The design process allows for ongoing innovation to occur throughout the project phases.

Investigation undertaken through the early design stage, found, progressing a planned future stage of the Smithfield Bypass now, rather than in the years to come, will bring major benefits to network functionality.

Traffic modelling for the revised design shows an overall better performing traffic network along both the Smithfield Bypass, and the CCH between McGregor Road and the intersection of CCH and CWAR. 

Key features of the preliminary design:

  • a future stage of the Bypass design is realised now rather than in 15 to 20 years
  • improved network functionality
  • enhanced safety outcomes
  • improved flood immunity for motorists
  • reduced construction and cost savings.

Key features of the design layout

  • Connection at CWAR and CCH upgraded to a four-legged signalised intersection
  • Four lanes on the approaches and departures at the southern connection of CWAR and CCH
  • Transition to a two-lane bridge over Avondale Creek
  • Two-lanes through to the McGregor Road overpass (bridge) on the northern connection to the CCH.

Note: certain aspects of the scope included in the Preliminary Design layout may change as the project undertakes the detailed design as part of the design and construct contract.

Local participation 

TMR is committed to maximising opportunities for local business and people to get involved in delivering the Smithfield Bypass Project.

Current works:

Early works continue in parallel to the detailed design stage, works include: 

  • Pre-loading culverts 
  • Relocation of water mains
  • Relocation of public utility services
  • Piling works for the construction of the first bridge. 

Works undertaken include: 

  • vegetation clearing and ground surface treatment prior to levelling and compaction
  • water quality monitoring
  • noise and dust monitoring along the bypass alignment.
