Captain Cook Highway – Smithfield Bypass

This $164 million project is a vital piece of infrastructure for the northern beaches of Cairns, in Far North Queensland.

The bypass has improved traffic conditions on the Smithfield road network by addressing congestion on the section of the Captain Cook Highway (CCH), between McGregor Road and the intersection of CCH and the Cairns Western Arterial Road. In particular, at the Smithfield, and Captain Cook Highway and Cairns Western Arterial Road roundabouts.

The Cairns Western Arterial Road has been upgraded to four lanes from the southern connection of the bypass to the traffic signals at nearby Caravonica State School, including installing traffic signals at the Skyrail Drive intersection.

In partnership with HDR, BG&E provided design management, civil and traffic engineering, and bridge and staging design services for the bypass.

An alternate design was developed by our team which improved the bypass’s functionality by attracting more traffic, thereby reducing congestion on local roads.

This also provides a significant whole-of-life cost saving, by eliminating the need for millions of dollars in additional infrastructure, which would be redundant within 10 years.
