This $110 million joint federal and state funded project saw the duplication of the Douglas Arterial Motorway, which forms part of the Townsville Ring Road. This transformed the existing two-lane road into a median-divided, four-lane motorway in order to support population growth and road infrastructure demands in the region.

The new 5.6km road follows the existing Department of Transport and Main Roads (TMR) reservation and alignment of the Douglas Arterial, with the two dual carriageways separated by a median or barrier where required.

A three-lane, 250m bridge across the Ross River was constructed upstream of the existing bridge, along with a two-lane bridge over University Creek. Grade-separated interchanges at two major intersections were also duplicated.

Delivered under a design and construct Early Contractor Involvement (ECI) contract, the project also featured earthworks, drainage, pavement, retaining walls, concrete barriers, signage and finishing works along with the duplication of four bridges.
