Project data

Location: Sydney, Australia

The NSW Hills M2 Upgrade will widen the existing motorway generally between Windsor Road, Baulkham Hills and Lane Cove Road, North Ryde, and will deliver four new ramps to improve access to the motorway. It is a key road freight and commuter route which connects the major employment hubs of Macquarie Park and Norwest Business Park. On a typical workday, the Hills M2 is used by more than 100,000 vehicles and over 17,000 bus commuters.
