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 is nearing completion and work remains underway at locations in Northbridge and West Perth.

Mitchell Freeway off-ramp lane restrictions from 31 May

From 31 May, there will be lane restrictions in place at Mitchell Freeway exit to Wellington Street and Roe Street off-ramp for six weeks. 

Drivers will not be able to continue to Wellington Street exit from the right lane of the ramp during the restrictions.

  • A new Mitchell Freeway off-ramp to Roe Street to replace James Street off-ramp
  • Approximately 500 m of new bus lanes on Charles Street
  • A new bus layover facility to complement operation of the nearby Perth Busport
  • A new shared path on Roe Street from Sutherland Street to Fitzgerald Street
  • Intersection improvements and modifications at:
    • James Street / Fitzgerald Street;
    • Roe Street / Fitzgerald Street;
    • Charles Street / Newcastle Street;
    • Charles Street / Carr Street; and
