The path uses Porous Lane, a permeable pavement surface made from recycled tyres, which will also help to protect the nearby mature trees.
The council’s head of transport, Gordon Naidoo, said: “The trees along the edge of Lake Domain Drive are around 40 years old, and maintaining their health and vitality is a top priority for Council.
“By using recycled tyres, we’re making sure water and oxygen can reach the tree roots, so these trees can continue to thrive for many years to come.
“At the same time, we’re reducing waste by giving old tyres a new purpose, so it’s a practical solution.”
City Delivery Committee chairwoman Sarah Thomson said being able to upgrade footpaths while protecting nature was a win.
“These trees have taken decades to establish ... so choosing a surface that protects their roots means we’re looking after today’s users and future generations at the same time.”
