General Information:

NorthConnex is a nine kilometre tunnel that will link the Pacific Motorway (M1) at Wahroonga to the Hills Motorway (M2) at West Pennant Hills. NorthConnex which will be completed in mid 2020, will be the longest and deepest road tunnel in Australia. Once the project is completed, drivers will not encounter a single traffic light from Geelong to Newcastle.

The Pacific Motorway (M1) was originally planned to continue as the Lane Cove Valley Expressway, which was to join the North Western Expressway, leading to the Sydney Central Business District via Gladesville Bridge (A40) and the Western Distributor, but those plans were cancelled in 1977. By the time the Pacific Motorway was extended to Wahroonga in 1989, there was no plan for a motorway route continuing beyond that location.
