Nicholson Road (Bridge) Over Rail


Traffic impact

The following roadworks will be in place to facilitate this project:

​Location​Estimated timeframe​Impact
Nicholson Road

Yale Road to Bannister Road

Ongoing until December 2017

24 hour works

  • Intermittent lane closures in both directions
  • ​Two lanes available in each direction during peak periods
  • Speed limit reduced to 40 km/h


Current status

Construction of a detour road was completed in the first quarter of 2017 and Nicholson Road traffic (from Bannister Road to Yale Road / Garden Street roundabout) has been realigned onto this temporary road. Diverting the traffic has allowed a new work area to be established, incorporating the footprint of the future bridge 

This temporary detour road is key to the staged construction methodology for the project

Work on site is now focused on ramp and bridge construction and will involve:

  • Removal of existing road;
  • Installation of services;
  • Delivery of materials;
  • Earthworks and compaction;
  • Installation of retaining wall panels;
  • Resurfacing; and
  • Installation of bridge beams, barriers, noise wall panels and lighting.

Nicholson Road has been reduced to two lanes in each direction for the works. Additional lane and road closures will be in place at night and during the day at off-peak traffic times.

Road and bridge works may cause delays and we request road users to plan their journey, allow extra travel time, and if possible avoid using Nicholson Road. Road users should be aware that traffic management will remain on the road at all times.


The Nicholson Road (bridge) Over Rail project includes road and bridge construction on Nicholson Road between Bannister Road, Canning Vale and Yale Road / Garden Street, Thornlie.

The new road bridge will take Nicholson Road over the Midland to Fremantle Freight Railway and remove the level railway crossing, which is used by about 30 trains per day. Nicholson Road carries about 44,000 vehicles per day and the boom gates, which are down for two minutes per train, interrupt traffic flows on Nicholson Road for up to 60 minutes per day.

The new traffic bridge will enhance traffic operations, economic efficiencies and safety by permanently removing the interface between the road and railway line.    

The project is jointly funded by the Australian and Western Australian governments.



Scope of Works

The works include:

  • A six-lane road bridge over rail
  • Road infrastructure including safety barriers, drainage, signs, screen/noise walls, pavement marking and street lighting
  • Modifying the existing road to maintain traffic flows during construction
  • Pedestrian and cycling infrastructure that includes a pedestrian underpass and a path on the east side of the new bridge.


Expected Timeframe

  • Construction start: December 2016 
  • Construction completion: December 2017
  • Landscaping works: 2018




Construction Reference Group

As the project will impact adjacent residents, a Construction Reference Group has been established to:

  • Assist in identifying, discussing and providing advice on community issues associated with the project
  • Exchange information between ourselves, the contractor and the community; and
  • Provide representative community and stakeholder input into the project.
