Regenerating our roads

Our focus on sustainability drives us to consider innovative ways in which disused sites near our roads can be regenerated. Through our Motorscapes projects, we aim to combine native bush regeneration with iconic public art or other social sustainability initiatives to benefit local communities and the environment.

Landcare Australia national partnership

Since 2014, Transurban has partnered with Landcare Australia to regenerate native vegetation along our assets. This year we worked with Landcare Australia on three key projects:

  • CityLink Tulla Widening Project
  • Motorscapes Power Street Loop, Melbourne
  • Motorscapes M2 Macquarie Park, Sydney

These projects have created valuable new greenscapes for local communities. They also enhance ecological value by attracting and providing habitat for local wildlife.

These projects further help Transurban connect with local communities and create volunteering opportunities for our employees.


Power Street Loop, Melbourne

Combining striking public artwork, sustainable construction practices, renewable energy and native ecosystem restoration, the regeneration of this one-hectare site has created a sustainable and vibrant urban space.

The regeneration of the Power Street Loop site, adjacent to CityLink, was focussed on creating community and environmental value. The project began in 2015 with a public art competition, continued with the fabrication, construction and installation of large-scale sculptural elements and ended with a public opening in 2016.

Habitat Filter, the winner of our public art competition, comprises a series of pods, the largest more than 25m-high, featuring a range of sustainability elements such as bird and bat nesting boxes and solar panels to reduce lighting energy needs. Recycled materials were used in the construction of the pods.

Transurban partnered with Landcare Australia to revegetate the site, and more than 40 Transurban employees, along with students from the nearby Victorian College of the Arts Secondary School, volunteered to help plant more than 18,000 seedlings and shrubs within the site. These plantings provide important biodiversity benefits to the urban landscape.

The Power Street Loop was developed using sustainable materials including:

  • Timber from reclaimed sources (100 per cent)
  • Recycled content in steel reinforcement (73 per cent)
  • Cement replacement in concrete mixes (34 per cent)
  • Recycled aluminium content (30 per cent)

The project also used energy-efficient LEDs for architectural lighting and a 10kW solar PV system for night lighting. A focus on local project sourcing ensured 80 per cent of suppliers and contractors were located within 30km of the site.

Kinetica, M2 Macquarie Park, Sydney

The M2 Macquarie Park Motorscapes project combined public art with native plants and habitats to transform a previously unused, five hectare site next to the Hills M2 Motorway. The completed project now adds interest and colour to the journeys of more than 100,000 motorists each day.

The project was launched in 2015 via a public art competition.  Sydney-based designers Justin Sayarath and Sarah Rodriguez won the competition for their 11-metre high artwork, Kinetica, representing native flora such as a waratah, banksias, wattles and eucalypts. Sustainability was a key criteria in selecting the winning design.

Alongside this, Transurban partnered with Landcare Australia to turn the site into an ecological buffer between the urban development of Macquarie Park and the neighbouring Lane Cove National Park. Dense, invasive weeds were removed from the site and 64,000 native seedlings planted. Local waterways were also rehabilitated as part of this project.

The project tested a range of sustainability initiatives including using:

  • An off-grid solar power plant to generate and store electrical power for Kinetica’s lighting and motor
  • Recycled crushed glass for pipeline bedding and backfill, saving 36 tonnes of virgin sand
  • Concrete containing fly ash, steel slag and recycled sand, saving 30 tonnes of virgin materials
  • Structural steel containing at least 25 per cent recycled content

Other sustainability features include the project’s flexible design, and the use of durable, long-lasting finishes and movement mechanisms requiring very little maintenance or materials. Overall, this project’s sustainability initiatives saw:

  • 705 tonnes recycled materials used
  • 64,000 native seedlings planted
  • 66 tonnes GHG emissions avoided
  • 50 tonnes of carbon sequestered annually once plants reach maturity

The M2 Macquarie Park Motorscapes project was officially completed in June 2017.

Heathwood Community Development, Brisbane

The Heathwood Community Development will redevelop a 0.65 ha site on Brisbane’s Logan Highway, at the Staplyton Road interchange. The project will create social infrastructure for residents in the local community, and is being delivered in conjunction with the Logan Enhancement Project.

In May 2017 we invited the community to submit their Expressions of Interest for the site, and expect construction to begin in mid-2018. The new public space is expected to open for public use in FY19.
