Project information


Motorists travelling westbound on the M5 Motorway through Moorebank currently experience traffic congestion in the afternoon peak. This is caused by traffic entering the motorway westbound at Moorebank Avenue, and merging with traffic already on the motorway that is looking to exit at Hume Highway. Increasing heavy vehicles travelling from the Moorebank Intermodal Park will also add to the congestion.


  • Provide a reliable road network to support economic and residential growth in western Sydney
  • Reduce congestion by removing the traffic weave
  • Improve safety and access to the Liverpool CBD
  • Provide pedestrian and cyclist connection across the Georges River.
  • Provide efficient, reliable travel between the Moorebank Intermodal Park and the state road network
  • Support the M5 Motorway as the key gateway for south‑west Sydney
  • Improve traffic flow across Georges River.

Recommended design

Transport for NSW has identified a design to upgrade the M5 Motorway westbound in this area to reduce congestion and improve the surrounding road network efficiency. The recommended design would include the following:

  • A new two lane bridge over Georges River and the T2, T3 and T5 railway lines, connecting the M5 Motorway and Moorebank Avenue to the Hume Highway
  • A new underpass at Moorebank Avenue for traffic exiting the M5 Motorway at Hume Highway
  • A new shared exit with Moorebank Avenue for traffic wishing to exit the M5 Motorway at Hume Highway
  • Closing the existing exit from the M5 Motorway to Hume Highway between Moorebank Avenue and Hume Highway.

What is happening now?

The contract for the review of environmental factors has been awarded and design work is now under way. The review of environmental factors was displayed from 29 August 2022 to 29 September 2022. Submissions are now closed.
