Project update

Installation of Scarborough Beach Road bridge
The bridge will be lifted and installed over Scarborough Beach Road from 28 to 30 September, followed by concrete pouring from 7 to 8 October. The works will require temporary closures of Scarborough Beach Road at Glendalough Train Station, with local access only from Main Street and Frobisher Street. See the Frequently Asked Questions for more information.

Preparation works for Scarborough Beach Road bridge

A dedicated cycling and pedestrian bridge is being constructed over Scarborough Beach Road. Preparation activities for the bridge’s installation are currently underway, and will continue until late September. The works include construction of embankments, concrete pads and noise walls, and the bridge being lifted over Scarborough Beach Road. See the latest Construct​ion Update​ for more information.

Shared path detours

From early August to September, the shared path at the Vincent Street exit will be closed between Richmond and Stamford streets in Leederville. The closure will allow for the construction of noise walls, withDetours in place.

A current path closure between Telford Crescent and Hutton Street in Stirling will remain until October, to allow for the construction of a Principal Share Path underpass at the Hutton Street exit. Detours have been in place since February.

AnInformation Sheet provides more information about cycling safety on detours.

Hutton Street temporary changes

Two cyclist underpasses are being constructed at Hutton Street as part of the new Principal Shared Path connection between Hutton Street and Glendalough Station. To enable these works, temporary on-and-off ramps at Hutton Street will be in place to maintain access at the freeway.

From 27 May to September 2019, access to Hutton Street from the freeway will be maintained via a temporary off-ramp. See theRoadworks update.

Access to the freeway from Hutton Street is maintained via a temporary on-ramp following changes implemented on 26 June. Access to the freeway from Hector and McDonald streets will be closed with detours via Cape Street until October. See theRoadworks update.

Environment and community

We are committed to ensure early and ongoing communication is undertaken throughout the project to ensure you stay up-to-date. As the project develops from concept to detail design, more information will be available for our stakeholders.

While there will be some impacts during construction, we will plan to minimise disruption and inconvenience to road users and nearby residents as much as possible.

We invite you to complete a short online survey to provide feedback on how the project has been communicated.

A Community Reference Group has been formed to:

  • Assist in identifying, discussing and providing advice on the community issues associated with the project
  • Exchange information between us, the contractor and the community
  • Provide representative community and stakeholder input into the construction phase of the project

The fourth meeting was held in April 2019.
