Interlink Roads owns and operates M5 South-West, Sydney

Opened in August 1992, the M5 South-West Motorway is a free flowing transit corridor spanning 22 km of Sydney's south west from Prestons to Beverly Hills.

The motorway is currently being widened, which will deliver better and more reliable travel times and an even safer trip. Find out more about the Widening Project.

The M5 South-West Motorway (excluding the the Georges River west bridges) is operated and developed by Interlink Roads under a lease that expires in 2026.

Several major roads including the F5 Freeway, the M5 East Freeway and the Westlink M7, connect to the M5 but are not managed by Interlink. Roads and Maritime Services, NSW, (RMS) manage these roads. See live traffic updates Live Traffic NSW.
