The Australian and NSW governments are funding a 10 year, $3.6 billion road investment program for western Sydney. The Western Sydney Infrastructure Plan will deliver major road infrastructure upgrades to support an integrated transport solution for the region and capitalise on the economic benefits from developing the proposed western Sydney airport at Badgerys Creek.
A new motorway is proposed to connect the M7 Motorway near Cecil Park to The Northern Road near Luddenham, to provide access and traffic capacity for the planned western Sydney airport at Badgerys Creek. The 14km motorway would be built for up to six lanes with a wide central median to separate opposing traffic flow.
The Northern Road Upgrade Glenmore Parkway to Jamison Road
In July 2015, Roads and Maritime Services released a preliminary design and access strategy for The Northern Road Upgrade between Littlefields Road, Luddenham and Jamison Road, South Penrith for community and stakeholder comment.
After reviewing the comments Roads and Maritime have now developed the concept design and Review of Environmental Factors for The Northern Road Upgrade between Glenmore Parkway and Jamison Road.
The proposed 4km upgrade is expected to start construction in the first half of 2017 and be open to traffic by 2020.
The Northern Road Upgrade Stage 4
Stage 4 is about 11km between Mersey Road, Bringelly and Littlefields Road, Luddenham. This important stage would divert The Northern Road around the western Sydney airport site at Badgerys Creek, west of the existing road.
The Northern Road Upgrade, Mersey Road to Glenmore Parkway
A preliminary design has been announced for The Northern Road Upgrade beteween Eaton Road and Littlefields Road, Luddenham. This upgrade will connect the relaigned The Northern Road Upgrade, Mersey Road to Eaton Road, with The Northern Road Upgrade, Littlefields Road to Glenmore Parkway.
The Northern Road and Bringelly Road Interchange
An upgrade for this intersection was previously approved as part of The Northern Road Upgrade. A grade separated interchange is now proposed at the intersection of Bringelly Road and The Northern Road as part of the Western Sydney Infrastructure Plan. Roads and Maritime is now considering route alignment options for further design and environmental assessment.
