The Eastern Distributor provides a fast,
efficient, easy link for travelling from the
north, south and east of the city. It provides
quick access between the city and the
airport. An important objective of the design
was to minimise the impact on the area
it passes through. The Eastern Distributor
provides a good example of how urban
design can create a blend between the
old and the new.
The six-kilometre motorway cuts city-to-
airport travel times by at least ten minutes
and bypasses 19 sets of traffic lights.
The Eastern Distributor tunnel tubes
are 1.7 kilometres in length and run from
Wooloomooloo to Surry Hills and are located
underneath one of Australia’s most densely
populated areas. The tunnel tubes are
arranged in a ‘piggy back’ configuration
with the northbound tunnel sitting on top
of the southbound tunnel.
How is air quality managed in
the Eastern Distributor Tunnel?
The tunnel air can be expelled through
two ventilation buildings, one at Darlinghurst
(for northbound traffic) and another at
Surry Hills (for southbound traffic) or through
the tunnel portals (entrances and exits).
Air is circulated through the tunnel by
a combination of vehicle movements and
the use of jet fans.
Air quality monitoring
Monitors in the Eastern Distributor tunnel
measure pollutant levels along the length
of the tunnel.
The tunnel operator carries out routine
testing of the air quality in the tunnel and
monitors it 24 hours a day to ensure levels
stay within the goals set by the former
Minister for Planning. For more information
