Charles Street Bus Bridge and Busway



Aimed at improving the reliability of bus services throughout Northbridge, we will deliver a new bus bridge and bus priority measures on behalf of the Public Transport Authority.

The project is to be funded by the State Government and aims to:

  • Reduce traffic congestion along James Street (west) and the south end of Fitzgerald Street
  • Establish a better bus service by providing on-time reliability improvements
  • Reduce travel time for passengers
  • Improve travel time for other road users
  • Reduce bus operating costs
  • Maximise benefits of existing investments, such as the Perth Busport


Current status

The project reached a major milestone with the realignment of the Mitchell Freeway southbound exit, from James Street to Roe Street on Sunday 18 December at 6am.  The first bridge segments were launched in November and work along the western verge of Charles Street is almost complete.

Watch our video for an illustrative drive through of the newly realigned Roe Street exit from Mitchell Freeway.


Work hours are from 7am to 7pm, although some works may need to be completed out-of-hours.  Look out for traffic management and shared path closures through the North Perth, Northbridge and West Perth area.
