The NSW and Federal Governments, Transurban and the M7 Westlink Shareholders (the Project Sponsors) are building and will operate and maintain a tolled motorway linking the M1 Pacific Motorway at Wahroonga to the Hills M2 Motorway at West Pennant Hills – called NorthConnex.


The nine kilometre tunnel motorway includes interchanges to the north and south to accommodate connections at either end of the project. When complete, it will link Sydney's north to the Orbital network and form part of the National Highway route.


As part of the wider Sydney road network, NorthConnex provides a direct connection from north to western and southern roads – keeping Sydney and the NSW economy moving.


The link between the M1 and M2 is recognised in the NSW Government's State Infrastructure Strategy and NSW Long Term Transport Master Plan as important infrastructure for freight traffic and the wider connectivity within NSW to reduce congestion and improve traffic flow along Pennant Hills Road.
