Careful planning has been carried out for the Southern Interchange. The key features of the interchange once operational include:

  • a northbound on-ramp and southbound off-ramp along Pennant Hills Road located south of Eaton Road;
  • tunnel on and off-ramps on the Hills M2 Motorway, which will emerge from underground tunnels within the motorway shoulder to the west of Pennant Hills Road;
  • no change to the existing arrangement at the Hills M2 Motorway interchange with Pennant Hills Road; 
  • motorists exiting the tunnel at the M2/Pennant Hills Road interchange can continue travelling south along Pennant Hills Road or turn left onto the eastbound carriageway of the Hills M2 Motorway;
  • motorists travelling north along Pennant Hills Road or exiting the westbound carriageway of the Hills M2 Motorway can use the on-ramp to travel north in the tunnel;
  • motorists travelling eastbound along the Hills M2 will have a motorway to motorway connection to the northbound tunnel;
  • motorists travelling from the north through the tunnel will have a motorway to motorway connection to the Hills M2 westbound.
