The Northern Road upgrade, Glenmore Parkway to Jamison Road

The Australian and NSW governments are upgrading The Northern Road as part of the Western Sydney Infrastructure Plan (WSIP), a $3.6 billion road investment program.

The Northern Road upgrade will deliver new and upgraded roads to support integrated transport in the region and capitalise on the economic benefits from developing the Western Sydney Airport at Badgerys Creek. It would also improve safety, increase road capacity and reduce congestion and travel times in the future.

This upgrade covers about 4 kilometres between Glenmore Parkway, Glenmore Park and Jamison Road, South Penrith. It is planned to generally follow the existing road alignment.

Updates and announcements

M4 Motorway closure – June long weekend

The existing bridge over the M4 Motorway now needs to be removed. To remove the key parts of the bridge there will be an extended full closure of the M4 Motorway at the interchange with The Northern Road. This closure is necessary to ensure motorists and our workers are safe and work is carried out as efficiently as possible.

The M4 Motorway will be closed at the Northern Road, South Penrith over the Queen’s Birthday long weekend from 9pm on Friday 7 June to 4am on Tuesday 11 June, weather permitting. Historical traffic data indicates that this weekend is a lower than normal traffic volume time to carry out this closure.

During the closure, the M4 Motorway will be closed to general traffic in either direction at The Northern Road.

Motorists are encouraged to avoid the M4 Motorway in this area during the closure and instead use alternative routes. The busiest traffic times are expected to be:

  • between 10am and 3pm on Saturday 8 June
  • between 10am and 2pm on Sunday 9 June

Please plan ahead and allow extra travel time if you need to be in the area, or travel on the M4 during the closure.

Diversions and detours will be in place during the closure. We have included a map to show the location of work and the main detour routes via the Great Western Highway that will be marked.

Vehicles will still be able to enter and exit the M4 Motorway in both directions at The Northern Road during the closure. However, motorists are advised to avoid the area for non-essential activities.

Electronic message signs will be updated during the closure based on traffic conditions in the area to direct motorists to the best available routes. Details are included in the following notification (PDF, 155Kb).
