Thomas Road Bridge Over Rail

The Armadale Access Alliance has been contracted to deliver the package of works on Thomas Road and have set up a site office on Plaistowe Boulevard, Byford.

Initial construction activities have begun with site testing and preliminary works underway.

Geotechnical Investigations

Geotechnical testing will take place from Monday 18 January to Friday 5 February 2021 to determine the physical and chemical properties of the soil and groundwater in the project area. Geotechnical investigations include below-ground inspection using borehole drilling and cone penetrometer testing.

The locations selected for the geotechnical testing have the least impact on existing vegetation and will require the possible removal of a small tree and bushes. See latest Construction Update for more information.

Where possible, works are planned to ensure minimal impact to the community, with the majority of construction activity scheduled between 7am and 7pm, Monday to Saturday. For the safety of road users and construction workers, some construction activities will be completed after-hours to avoid disruption to daytime traffic.

• It will be the first level crossings between Armadale and Byford to be reconfigured to accommodate the rail project, which will provide commuters with a 42-minute journey into Perth. Options are being considered for the remaining level crossings. 
• Significantly reduce congestion at the eastern end of Thomas Road and improve safety by modifying access points on local roads.
