NorthConnex is a major road infrastructure project taking place in Sydney’s North-West. It is a 9km tunnel which will go underground (up to 90m at the tunnel’s deepest point, under the North West Rail Link Tunnel) connecting the M2 Hills Motorway & Pennant Hills Road to the M1 Pacific Highway Interchange.

On Completion, NorthConnex will become Sydney’s & Australia’s largest underground road project. However, it will be overtaken once the WestConnex M4-M5 Link Tunnel is completed.

The developer & operator of the NorthConnex tunnel will be Transurban. This will be a Motorway meaning it will be a toll-road which motorists will be required to pay a fee everytime they go through it.

Here are the expected toll feed upon NorthConnex Opening the tunnel:

Cars: A$6.41

Trucks: A$19.25

Toll prices are expected to increase in line with the proposed concession agreement with the Government which will end in the year 2048.
