Page 8 - Air Quality In Tunnels

Basic HTML Version

The Lane Cove Tunnel improves local
air quality by reducing traffic volumes on
Epping Road. These air quality improvements
extend several hundred metres either side
of Epping Road.
How is air quality managed
in the Lane Cove Tunnel?
Air quality in the tunnel is managed with
two ventilation buildings: one at the western
end, in the Lane Cove West Industrial Park
in Sirius Road; and one at the eastern end,
in the Artarmon industrial area, between
the western end of Marsden Street and the
Pacific Highway. The ventilation buildings
are connected to exhaust points that are
located at various points in the tunnel.
Fresh air is drawn into the tunnel via the
portals (tunnel entrances and exits) and
an intake located at 130-132 Epping Road,
Lane Cove. Strategically positioned jet fans
along with the movements of vehicles
assist with the flow of air.
Air quality monitoring
Monitors in the Lane Cove Tunnel measure
pollutant levels along the length of the tunnel.
Air quality is also measured in the ventilation
buildings. The tunnel operator carries out
routine testing of the air quality in the tunnel.
The air quality standards for the Lane
Cove Tunnel project were set down in the
former Minister for Planning’s Conditions of
Approval. Air quality data is available to the
public on the tunnel operator’s website at

Inside the Lane Cove Tunnel
The Lane Cove Tunnel is a 3.6 km twin
tunnel motorway under Epping Road that
links the M2 Motorway at North Ryde
with the Gore Hill Freeway at Artarmon.
The Lane Cove Tunnel delivers a number
of benefits including quicker travel times
between the north-west and the city,
provision of a direct link to the Sydney
Orbital Network and a route that bypasses
five sets of traffic lights, both east and
westbound, along Epping Road.
