New noise walls are needed here to fill an existing gap.

The new walls will use colours drawn from the surrounding landscape including rock and stone and be made of recycled plastic moulded into patterns that complement the existing concrete noise walls in the area. Recycled plastic has excellent sound absorption qualities and makes the project more sustainable. It also means new noise walls are lighter, so they can be installed more easily, with less heavy machinery and less disruption.

The new wall is expected to be around 10m tall, with new trees and plants along Koonung Creek Trail for screening.
