Restoring the natural environment along our motorways is important to local communities and us. We do this through our major construction projects - for example, the West Gate Tunnel Project in Melbourne will plant 170,000 trees and one million shrubs. And in our day-to-day operations by looking for sites next to our motorways that we can regenerate.
Twice we have partnered with Landcare Australia and local artists to restore unused sites. The first time we regenerated a one-hectare site next to CityLink in Melbourne. The restoration of the natural ecosystem was combined with the installation of an iconic public artwork, called Habitat Filter.
More than just being visually attractive, the artwork contains nesting boxes for birds and bats, solar panels to offset night-time lighting and was constructed using recycled materials.
The second time, we regenerated a five-hectare site next to the Hills M2 Motorway in Sydney. Restoring the natural ecology included improving the water quality of a local creek and planting thousands of trees. Another piece of public art was commissioned, called Kinetica, and this represents native flora.
