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 funded by the State Government and has:

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


Current status

The project is nearing completion with the bus bridge and busway starting operations on 25 June. Road and building work remain underway at locations in Northbridge and West Perth.

Mitchell Freeway off-ramp lane restrictions from 31 May

Lane restrictions remain in place at Mitchell Freeway exit to Wellington Street and Roe Street off-ramp until the end of August. 

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

Follow on-site signage and select the correct lane well in advance of the exit you wish to use - choosing the left lane for Wellington Street only and the right lane for Roe Street only.

  • 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
