Leighton Holdings Ltd subsidiary Thiess has won a $650 million contract to deliver the Moreton Bay rail link.
In a statement to the Australian Securities Exchange, Leighton said the link would be a major suburban growth corridor in South East Queensland.
"Thiess is the construction spearhead of the Trackstar team which includes design subcontractors Aurecon, AECOM, HASSELL, and geotechnical subcontractor Golder Associates," the group said.
The 12.6 kilometre rail link will connect the greater Brisbane rail network, which currently ends at Petrie, to the rapidly growing Moreton Bay region.
Leighton Holdings chief executive officer Hamish Tyrwhitt said the contract award reinforced the diversity of the group's portfolio.
"It’s very pleasing to note that in the past six weeks we have on-boarded in excess of $5.5 billion of projects, tangible proof that we can continue to sustain our work in hand, notwithstanding any challenges we may face in the coal sector," he said.
"For the nation, the Moreton Bay Rail Link demonstrates a growing recognition of the need to fill our infrastructure deficit in order to remain globally competitive."
