What is NorthConnex?
• NorthConnex will provide the vital
link between Hills M2 Motorway
and the M1 Pacific Motorway.
• Two key components – Tunnel and
M2 Integration Works
• Australia’s longest and deepest road
tunnel – longer than the Eastern
Distributor, M5 East and Cross City
tunnels combined

Project scope
• Twin motorway tunnels - nine kilometres in
length / two lanes plus a breakdown lane in
each direction, and a speed limit of 80 km/h (or
90?)
• Each tunnel will be built with future capability to
provide three lanes in each direction at reduced
speed
• A northern interchange connecting with the M1,
the Pacific Highway & Pennant Hills Road
• A southern interchange connecting with the Hills
M2 Motorway and Pennant Hills Road

8
• A motorway control centre and ancillary
buildings, southern and northern ventilation
outlets and water treatment plant near the
southern interchange
• Ancillary facilities for operation, such as
electronic tolling facilities, ventilation
facilities as well as fire and life safety
systems
• Two additional smoke exhaust shafts in the
event of an underground fire
• Modifications to service utilities and
associated work at surface roads near the
two interchanges

Project Design Features
Standard Cross Section Main Carriageway
2 lane tunnel designed for future 3 lane use
Dynamic envelope = 10.5m x 5.3m
Tunnel Concept :
- Mechanized excavation using road headers / rock boltings and shotcrete
- Drained tunnel: 1l/s/km allowable water inflow limit.
- Waterproof membrane to divert water away from tunnel crown

Program of Works
Tunnelling – Basic scheme
General sequence of excavation:
1- RH excavation 1- XP Excavation 2- Benching 3- Lining / waterproofing
(1 activity in the program)
4- Drainage/Cable pit 5- Paving (no fine, asphalt, CRCP)
excavation ducts install backfill
Access to M&E Blue: Civil Activities
7- Cable Pulling Red: M&E Activities
7- M&E 1st Fix (cable trays, fans, cables)
6- Traffic Barriers fundation 7- Cladding frame support 8- Install Traffic Barriers
Access to M&E 11- Commissioning
9- Infill Concrete 10- M&E 2nd Fix (cable termination) 11- Cladding installation
11- Low noise diamond grind, pavement, line mark
together
Benching starts once excavation for full length of regular section is
completed by Road header
Enlarged section will be excavated once full length of regular section
is completed by road header
