The WestConnex will link the M4 to the M5 via Sydney Airport, integrating a 13km tunnel as part of the new plans. Construction will start in 2015and as each stage is completed parts of the motorway will be opened with the final stage due to open in 2023. Another tunnel, running from Balmain to Lane Cove, is expected to support the 33km WestConnex motorway, making it easier for motorists to drive between Sydney’s western suburbs and denser inner areas.


Lend Lease has won the contract for the $2.6 billion NorthConnex motorway in Sydney, giving the group its second controversial tunnel project in six months.  The project will provide a link between the southern end of the M1 Pacific motorway at ­Wahroonga to the Hills M2 ­motorway at its existing Pennant Hills Road interchange. Lend Lease is in a joint venture with French entity Bouygues Construction to deliver the project on behalf of Transurban which will operate the road. Spanning 9km, NorthConnex will be the longest road tunnel project in Australia. Construction of the tunnel will begin in early 2015 and is expected to be completed in 2019.
