M5 West widening - Building Sydney's Motorways

The M5 West Widening project has been completed on time and on budget - cutting travel times for motorists on one of Sydney's most important and busiest road corridors.

This project has increased the capacity of the M5 South West Motorway by 50 per cent by adding a third lane in each direction and reducing congestion, and is expected to provide travel time savings of 20 to 25 per cent for motorists in the morning and evening peak periods.

The $400 million M5 West Widening project was primarily funded by Interlink Roads, with the NSW Government contributing $50 million towards the cost of new and improved noise walls and noise mitigation measures for nearby residents.
