​Broadspectrum and EastLink work with community to enhance sustainability of Melbourne's EastLink tollway

The Mullum Mullum tunnel portal on Melbourne’s EastLink tollway now features a green area with thanks to Broadspectrum, client EastLink, Swinburne University of Technology and its students, and local residents.

Around 2,000 square metres of recreation space now sits on top of the tunnel portal, which also contributes to greater diversity of flora and fauna.

Peter Richardson, Chief Executive for Transport at Broadspectrum, said: "We are really happy to have been involved in helping our client, EastLink, and the community in delivering environmental and social outcomes that can be enjoyed by the local community for years to come."

The landscape solution was created by two students from Swinburne as part of their studies. With the support of EastLink and Broadspectrum, they conducted field studies, interviewed residents in the local community, and engaged the services of an agronomist.

Their solution, and the judging criteria, focused on soil amelioration, plant establishment, the need for irrigation, and ease of maintenance. The site was prepared by Broadspectrum, and a community planting day brought the area to fruition.

Community participation and collaboration played an essential role in bringing this project to fruition, from a survey of residents’ opinions about design requirements to the final selection and planting.

The cooperation between the local community, the university and EastLink has revitalised the landscape, creating a habitat for wildlife.

Broadspectrum has partnered with EastLink to operate and maintain this 40-kilometre highway and its tunnels since opening in 2008. EastLink is the fastest and safest road in Melbourne, carrying 250,000 vehicles per day.

In the internationally recognised 2019 GRESB Infrastructure Sustainability Assessment, EastLink was awarded the top 5 Star rating for the fourth consecutive year.
