NorthConnex will be a twin nine kilometre dual-lane tunnel linking Sydney's M1 Pacific Motorway (at Wahroonga) with the Hills M2 (at Pennant Hills Road). The tunnel design includes capacity for future expansion to three lanes and will accommodate vehicles up to 5.3 metres high.
When complete, NorthConnex will link Sydney's north to the orbital network, and will form part of the National Highway route. In the future, motorists will be able to drive from Melbourne to Newcastle – with no traffic lights from start to finish.
NorthConnex was awarded a ‘Leading’ Design Rating by the Infrastructure Sustainability Council of Australia.
Once complete, NorthConnex will:
- reduce traffic congestion by diverting up to 5,000 trucks per day from Pennant Hills Road
- offer motorists up to 15 minutes in saved travel time
- allow motorists to bypass up to 21 traffic lights
- return local streets to local communities
- create more efficient freight movement
- provide opportunities for improved public transport
- integrate with the regional transport network by connecting the orbital network with the M1
The project is creating 8,700 jobs.
Timing and cost
Construction on NorthConnex started in 2015 and is due for completion in 2020.
The $2.9 billion project comprises a $2.65 billion design and construction contract (delivered by Lend Lease and Bouygues Construction), along with land and project delivery costs.
NorthConnex will be funded through toll charges and through contributions from the NSW and Australian governments of up to $405 million each.
Transurban owns 50 per cent of this road.
