It’s Australia’s deepest road tunnel, up to 90 meters below ground. Our iconic NorthConnex project, in joint-venture with Lendlease,  opened to motorists Saturday 31 October.

The dual 9km tunnel, linking the M1 Pacific Motorway at Wahroonga to the Hills M2 Motorway at West Pennant Hills, features large 3.5 metre lanes and will accommodate vehicles up to 5.1 metres high.

NorthConnex is designed to take 5,000 heavy vehicles off Pennant Hills Road. It also allows motorists to bypass up to 21 sets of traffic lights.
