CityLink Tulla Widening

Sustainable construction

The CityLink Tulla Widening project was awarded an Excellent Infrastructure Sustainability Design Rating. This rating reflects the project’s sustainable construction approach, including:

  • Sourcing 32.5 per cent of water from non-potable sources such as water tanks, treated process water and dewatering during digging
  • Changing the design to reduce the overall quantities of materials such as concrete, steel and asphalt. These changes reduced the lifecycle impact of materials used on the project by 25 per cent compared to the base case footprint
  • Reusing around 20,700m3 of cleared topsoil in newly planted areas of the landscape design


Around 150,000 trees and shrubs will be planted along Transurban's Bulla Road to Power Street section of the CityLink Tulla Widening project corridor. These plantings will replenish and enhance Melbourne’s green spaces.

We also completed an urban landcare project in partnership with Landcare Australia and local communities to transform local CityLink Tulla Widening project sites into healthy, vibrant spaces.

Connecting with the community

The project’s sustainability grants program awarded three grants of $5,000 each to local community groups with an initiative that will improve the quality of life for locals and the environment along CityLink, between Power Street and Bulla Road.
