The Hills M2 Motorway is a 21-kilometre road linking Sydney's lower north shore and the northwest regions. The M2 Motorway connects with Westlink M7, the Lane Cove Tunnel, and the NorthConnex tunnel. The motorway was first opened in 1997, with a widening and upgrade completed in 2013. Transurban took over operational control the M2 Motorway in 2005 and in 2014 Transurban (via NSW subsidiary TollAust) acquired 100 per cent of the operations management on the motorway. The M2 Motorway is under concession until 2048. Ventia are the current Operations and Maintenance contractors.
