We fully recognise the importance of Sydney Park and the investments that the City of Sydney Council and others have made in recent years.

A strip of land owned by Roads and Maritime Services adjacent to Sydney Park is being used to widen Euston Road as part of local road upgrades. This is not part of Sydney Park.

As outlined in the City of Sydney’s own management plan for Sydney Park, this land is dedicated road space and has been subject to a long-standing road widening reservation.

A small boundary strip, adjacent to the road reserve, is also required for the local road widening, however this is more than offset by the additional 8.5 hectares of open green space being created at St Peters Interchange.

Two hectares of this open green space will be directly connected to Sydney Park via a land bridge over Campbell Road.

Transferring vehicles from surface roads into free-flowing underground motorway tunnels will improve the air quality along existing surface roads where traffic is reduced.

For example, an independent air quality assessment detailed in the M4 East EIS found air quality will generally improve along the Parramatta Road corridor because of traffic shifting to WestConnex.

Motorists will have a smooth motorway to travel on, rather than being stuck in congested, stop-start traffic with traffic lights, and this will reduce emissions.

Our tunnels are also designed to reduce emissions, as they are generally flatter and less steep at the entries and exits.

WestConnex is generating more than 18 hectares of new open space for communities in the inner west. 

We sometimes use parks and other government-owned land during construction. This helps us to avoid the acquisition of private property. When we use green space during construction, we always try to return it for community use when construction is finished.
