The Northern Road upgrade $1.6 billion of the infrastructure plan was used to fund the upgrade of of
The Northern Road between The Old Northern Road at
Narellan and Jamison Road at
South Penrith, including road widening to a minimum of four lanes. Originally made up of four stages, the project was delivered in six stages, numbered by chronological order of construction commencement. The stages arranged from north to south are stages 3, 5, 6, 4, 2 and 1. Some sections of Stages 4 to 6 that were critical to the delivery of the
Western Sydney Airport were opened in stages from 2020. A new underpass with The Northern Road was also constructed as part of The Northern Road upgrade, opened in July 2020. The second stage between King Street and The Northern Road was completed in December 2020. The interchange with M7 will open later that year.

The federal government contributed 50 per cent of the cost of the $52 million upgrade. The federal government funded $2.5 million towards the $5.6 million project.
