Leighton Holdings Limited (ASX:LEI) has been selected to construct the M4 widening in the first stage of the WestConnex project in a deal worth $150 million.
The construction and engineering company says the M4 widening will upgrade 7.5km of the motorway from three lanes up to four lanes.
CEO Marcelino Fernandez Verdez says with strong levels of investment in projects such as WestConnex, transport infrastructure will continue to be a significant market for the Leighton Group.
The WestConnex Delivery Authority chose Leighton Contractors as part of a joint venture with Rizzani de Eccher Australia.
Leighton Holdings reported a net profit of $285 million in the first half of the 2014 calendar year.
