NSW Premier Gladys Berejiklian and Minister for WestConnex Stuart Ayres have announced that two joint ventures have been shortlisted to build the M4-M5 Link, which is the third stage of WestConnex and will link the New M4 Motorway at Haberfield to the New M5 Motorway at St Peters.
"With the widened M4 set to open on Saturday 15 July and tunnelling past the halfway mark on M4 East tunnels, we are moving forward with the final stage of WestConnex which will provide congestion relief for thousands of drivers a day," Ms Berejiklian said in a statement last week.
"In four weeks from now drivers will be able to experience the widened eight kilometre stretch of the M4 between Church Street Parramatta and Homebush Bay Drive at Homebush, toll free for a month."
The M4-M5 Link mainline tunnel will be delivered as a stand-alone project, initially operating independently from the Rozelle Interchange and Iron Cove Link, allowing the link to potentially open early to drivers in 2022.
Minister for WestConnex Stuart Ayres said two joint ventures were shortlisted to design and build the mainline tunnel between Haberfield and St Peters, after the release of the concept design last month.
"John Holland CPB Contractors joint venture and Lend Lease Samsung Bouygues joint ventured have been selected to tender for the M4-M5 link which will create a non-stop underground western bypass of Sydney CBD," Mr Ayres said.
"The M4-M5 Link is the most important stage of WestConnex as it will provide the vital connection between the new and upgraded M4 and M5 motorways for tens of thousands of vehicles a day and connect to Port Botany, the Airport and future M6."
Federal Minister for Urban Infrastructure Paul Fletcher said the Commonwealth was pleased to be supporting WestConnex with $1.5 billion in grant funding and a $2 billion concessional loan to the NSW Government.
Work to build the M4-M5 Link is due to start in 2018 with the new M4 tunnels to open in 2019.
The approximate $16.8 billion, 33-kilometre WestConnex tollway is being delivered across stages, with the M4-M5 link forming the final stage. The overall project will extend from Parramatta to Sydney's CBD, Sydney Airport and the Port Botany precinct and the M5 in south-west Sydney, and carry an estimated 400,000 vehicles per day.
