Mount Ousley Road/M1 Princes Motorway

Mount Ousley Road, renamed the M1 Princes Motorway, carries significant commuter, heavy vehicle and recreational traffic.

Project background

Roads and Maritime has a number of projects being carried out to improve safety for road users in this area including:

  • Safety upgrade for northbound traffic entering the M1 from Picton Road
  • Interchange at the intersection of M1 and Old Mt Ousley Road.

Safety upgrade - Picton Road/M1 intersection (northbound)

Current activities

Roads and Maritime Services has completed the  safety upgrade at the intersection of the M1 Princes Motorway (Mt Ousley Road) and Picton Road. The upgrade has improved safety by adjusting the access to Sydney from Picton Road to remove the current T-intersection and building an acceleration lane on the M1.

M1 interchange at the base of Mt Ousley

Roads and Maritime has begun planning for an interchange on the M1 at the base of Mt Ousley and will also explore opportunities to install a third southbound lane from about 650m north of New Mt Pleasant Road to Mount Ousley Road, a total distance of about 2.5km.

The interchange will look at future traffic growth and improve road safety at the base of Mt Ousley.
