Applicants have been shortlisted to build the M4-M5 Link of the WestConnex Rozelle Interchange and Iron Cove Link.

Minister for WestConnex, Stuart Ayres, said JCL Joint Venture (John Holland CPB Contractors Lend Lease) and SCS Joint Venture (Salini Impregilo Clough Projects Samsung C&T) have been shortlisted for the next stage of the bidding process, after a rigorous evaluation process.

“The M4-M5 Link is the most critical section of WestConnex and will for the first time link the New M4 and New M5 motorways, providing seamless underground travel for tens of thousands of vehicles every day,” Mr Ayres said.

“The Stage 3A mainline tunnels will run for 7.5km between Haberfield and the New M5 in St Peters with four lanes of traffic in each direction, connecting to the Rozelle Interchange and Iron Cove Link (Stage 3B).”

The Rozelle Interchange and Iron Cove Link will provide a new underground motorway interchange to City West Link and underground bypass of Victoria Road between Iron Cove Bridge and Anzac Bridge with links to the future Western Harbour Tunnel.

Bidders will develop, refine and optimise solutions for the design and construction of the Rozelle Interchange and Iron Cove Link, using a Collaborative Contractor Client model led by Roads and Maritime Services.

The CCC model will allow the NSW Government and industry to work together to knowledge share and leverage the opportunities of the project.

Construction of the M4-M5 Link tunnels is expected to start later this year and open to traffic in late-2022 with the Rozelle Interchange and Iron Cove Link operational about 12 months later.

The next stage of WestConnex, the New M4 twin tunnels between Homebush and Haberfield are set to open in the first half of next year with the New M5 tunnels to open in 2020.
