AECOM and Seymour Whyte worked together to deliver this complex D&C project (Seymour Whyte in joint venture with Abigroup). The works required innovative engineering, construction and project management to meet council and community expectations within very strict funding and contractual arrangements.

This complex design and construct project was delivered in three sections:

  1. Section 1 involved a new two-lane, 2.5km road connecting the Flinders and Bruce highways, including a grade separation of the North Coast Rail Line
  2. Section 2 was a new 7.5km link from the Bruce Highway into the Port of Townsville, including 4 bridges and 14 drainage structures, including provision for two additional lanes
  3. Section 3 involved the construction of a multi-span bridge over the Ross River, linking the new access corridor to the Port.

The Townsville Port Access Road was the first project in Queensland to be granted a Beneficial Reuse Licence from the Department of Environment and Resource Management (DERM) for use of recycled truck tyres in permanent creek bank stabilisation solutions. Known as Ecoflex, it provided an innovative engineering solution using recycled truck tyres and crushed concrete in the construction of structural working platforms to support a 110-tonne piling rig. More than 2,200 truck tyres filled with crushed rock and concrete were used to build a low impact, erosion resistant Ecoflex platform within the Stuart Creek riparian zones. This innovative solution minimised the construction footprint of the project and removed approximately 2,300 truck tyres from landfill to provide a safe and stable platform for the team to work on. Direct cost savings of some $70,000 were gained compared with other construction methods.

In addition, part of the environmental impact management strategy involved the development of an onsite mobile water treatment and dosing system to deal with the highly turbid and caustic water produced by pile dewatering activities. Nearly 2,000KL of water was treated for discharge and dust suppression. This reduced vehicle movements to and from the site, generating savings of more than $400,000.
