Douglas Arterial Duplication
Location: Townsville, Queensland
A design and construct Joint Venture with Abigroup, the Douglas Arterial Duplication was awarded through an ECI bid process. The project involved transforming the existing Douglas Arterial road into a median-divided, four-lane motorway. The new 5.6km road follows the existing TMR reservation and alignment of the Douglas Arterial, with the two dual carriageways being separated by a median or barrier where required.
A new 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.
During construction, the scope of the project was extended by a number of variations, the most notable being the inclusion of on and off ramps to the south of Ross River. The project proved to be quite challenging from a number of viewpoints, such as: Ross River Bridge and the use of the launching truss to install girders; disjointed earthworks sections broken by bridges and retaining walls, and strict environmental requirements.
The management of traffic flow and maintaining connectivity, particularly for the local residents, university and hospital, was vital in the delivery the project.
The completed project provides the following benefits to road users:
- Increased traffic capacity, which will reduce operational costs by improving trip times and reducing queuing behind heavy vehicles
- Improved safety by providing a median-divided dual carriageway and opportunities for safe overtaking, thereby reducing both the chances of accidents and the severity of any accidents that might occur
- Increased efficiency of the route as a transport corridor through reduced travel times, thereby improving the productivity of nationally strategic and export-oriented freight corridors
- Improved reliability of travel on interstate and interregional corridors
- Improved travel along the primary connection between northern Townsville and industrial centres in Stuart.
