Monash Freeway Upgrade

The Monash Freeway Upgrade will improve safety and reliability along the 44 kilometres between Chadstone and Pakenham, extending what is already Australia's longest stretch of managed motorway.

The upgrade is part of the $5.5 billion Western Distributor Project and includes 30 kilometres of extra traffic lanes along with major improvements to the managed motorway system.

Key features include:

  • Widening the freeway from four to five lanes each way between the EastLink interchange and South Gippsland Freeway
  • Widening the freeway from two to three lanes each way between the South Gippsland Freeway and Clyde Road in Berwick
  • Ramp signals added from Chadstone to Pakenham, to help prevent stop-start driving conditions and dangerous sudden braking
  • Lane Use Management Signs (LUMS) installed between Warrigal Road and the South Gippsland Freeway to improve traffic flow by providing drivers with information in the event of an incident. Automatic Incident Detection will work alongside LUMS to provide real time alerts to the traffic control centre, further improving the effectiveness of the freeway during an incident.

These improvements mean the M1 will be a managed motorway from Duncans Road in Werribee to Koo Wee Rup Road in Pakenham around 90 kilometres connecting Melbourne's east and west.
