NorthConnex is a nine kilometre twin tunnel linking the M1 Pacific Motorway at Wahroonga to the Hills M2 Motorway at West Pennant Hills in Sydney’s north. It will deliver significant benefits to local communities by easing congestion and removing up to 5000 trucks per day from Pennant Hills Road. This will help improve safety, benefit local air quality and reduce traffic noise.​
