NorthConnex is a 9-kilometre twin tunnel linking the M1 Pacific Motorway at Wahroonga to the Hills M2 Motorway at West Pennant Hills in Sydney’s north.
It is the missing link in the National Transport Network improving freight access, connectivity and reliability across Greater Sydney. NorthConnex has been designed to the highest safety standards and as a solution to bypass one of NSW’s most congested routes, Pennant Hills Road.
NorthConnex is electronically tolled with no cash tollbooths. Linkt accounts and passes can be used to pay for NorthConnex tolls. To pay for your travel, open a Tag account, a Tagless account or buy a Sydney Pass.
