The companies are Thiess John Holland Joint Venture, Lend Lease Bouygues Joint Venture and GlobaLink Joint Venture consisting of Ghella and Acciona Infrastructure Australia. The project has a target price of AU$2.65bn (£1.56bn),
The NSW government has received an unsolicited proposal from private motorway operator Transurban and the Westlink M7 shareholders last year to build the link along the Pennant Hills Road corridor.
Transurban started an expression of interest process in July with interested bidders and has shortlisted three consortia who will be invited to tender for the design and construction of the project.
The proposed tolled link will be jointly funded by Transurban, Westlink M7 shareholders and the NSW and federal governments.
Initial investigations and studies have started for the environmental assessment of the proposed link with further work to continue until early 2014. The NSW government and Transurban hope to have a conditional preferred tenderer selected by early 2014.
