The NorthConnex tunnel ventilation system will include two ventilation outlets located near the southern and northern tunnel portals.
The Northern Ventilation Facility will be located on the western side of the M1 Pacific Motorway at the corner of Bareena Avenue and Woonona Avenue North. It will acco妹妹odate the outlet, a substation, two water tanks and a fire services pump room. The site will serve as a temporary construction site for the duration of the project.
The Southern Ventilation Facility will be located on the north-western corner of the Hills M2 Motorway and Pennant Hills Road intersection. The site has been co-located with other operational facilities to reduce the amount of land acquisition required. The outlet is around 15 metres from Pennant Hills Road. |
