The Hume Highway Southern Alliance (HHSA) project was completed in August 2009, four months ahead of schedule and within its A$377 million budget.
The alliance undertook planning, design and construction of new highway infrastructure, which included duplication next to existing sections of highway and a ‘Greenfield’ section on a new alignment.
SKM provided road, bridge and drainage engineering design, as well as leading the environmental approvals and management, as part of the alliance alongside the NSW Roads and Traffic Authority and Abigroup Contractors.
