Supporting growth and connecting communities with Perth’s first east-west cross line.
The METRONET Thornlie–Cockburn Link was completed in June 2025 after four years of delivery by the NEWest Alliance.
Delivered for WA’s Public Transport Authority, this landmark project has transformed Perth’s public transport network by delivering the city’s first east-west cross line connection. As an Alliance member, DT Infrastructure played a critical role in seeing the project to completion, enhancing connectivity across the metropolitan area. The new line is key to supporting economic growth by providing more efficient access to employment hubs, recreational precincts and entertainment destinations.
The project created 1,700 jobs while delivering large-scale infrastructure improvements, including the construction of the new Nicholson Road and Ranford Road stations and major upgrades at Thornlie, Cockburn Central and Perth Stadium station.
