Major milestone for M4-M5 Westconnex tunnel link

Media Release


13 June 2018

Joint release with:

Stuart Ayres

NSW Minister for WestConnex

The NSW Government has today announced the successful tenderer for construction of the mainline tunnel of the M4-M5 Link as the LSB Joint Venture, comprising Lendlease Engineering, Samsung C&T Corporation and Bouygues Construction.

Federal Minister for Urban Infrastructure and Cities Paul Fletcher said today’s announcement is a major milestone for WestConnex.  

“This is the crucial final piece of this transformational infrastructure project. WestConnex is delivering a skills legacy, with more than 10,000 direct and indirect jobs created over the life of the project,” Mr Fletcher said.

“This will mean a quicker, safer and more reliable journey for commuters and 10,000 fewer trucks on Parramatta Road east of Concord.”

WestConnex Minister Stuart Ayres said: “This is a significant day for a project that will help thousands of motorists everyday by easing congestion on M4, M5 and Parramatta Road.”

“The M4-M5 Link is the most important stage of WestConnex, providing a vital connection between two of Sydney’s busiest motorways.  We are linking the New M4 at Haberfield with the New M5 at St Peters, creating a western bypass of the CBD.”

CEO of Engineering and Services at Lendlease Craig Laslett said: “The M4-M5 Link is a critical project that will drive Sydney’s economic growth and deliver new jobs and training opportunities.”

CEO of Samsung C&T Corporation Youngho Lee said: “It is a privilege to continue to work with the NSW Government to deliver this crucial project, increasing local training opportunities and employment whilst addressing Sydney’s future transport needs.”

The mainline tunnel will include up to 7.5km kilometres of twin tunnels, associated ramps and supporting operational facilities.

Work on the M4-M5 link will get underway later this year. For more information visit
