Improving our networks

As populations increase and our cities rapidly grow, transport networks are struggling to keep pace. Some studies show that motorists in Melbourne and Sydney are spending up to 76 hours and 90 hours, respectively, stuck in traffic each year. 

Transurban is working closely with our government partners to meet the future needs of our cities by improving existing networks and alleviating severe congestion. Projects include CityLink-Tulla widening in Melbourne and NorthConnex project in Sydney (see Case studies: CityLink-Tulla widening and NorthConnex). 

Sustainability is central to how we design and build these projects and how they are operated once complete. To achieve the best possible sustainability outcomes we are working with the project teams and suppliers to develop sustainability targets and encourage the use of rating tools such as the Infrastructure Sustainability Council of Australia’s IS Rating Tool, which evaluates sustainability across design, construction and operation.

A requirement for the NorthConnex project was that the successful contractor commits to achieving a minimum ISCA rating of ‘Excellent’. In addition, we asked shortlisted consortia to provide an outline of how the project could:

  • Better manage resources by cutting down on waste, re-using materials and incorporating materials with a lower environmental footprint
  • Consider new approaches, including smart technologies, to reduce energy use during design, construction and operations, and
  • Support economic development in the local community by purchasing from businesses in the area and training and hiring labour within the project corridor.

This resulted in high quality sustainability management plans being submitted, addressing our overarching sustainability objectives for the project.
