Warnbro Sound Avenue and Bluestone Parkway Roundabout Modifications

  • Infrastructure projects
  • Planning and design

Project summary

We're modifying the northbound road alignment to reduce the entry speed into the Warnbro Sound Avenue and Bluestone Parkway roundabout in Secret Harbour.

As part of the City’s ongoing commitment to improving road safety, we will be constructing speed deflection along Warnbro Sound Avenue, travelling north towards the Bluestone Parkway roundabout.

These upgrades aim to slow vehicle speeds as they enter the roundabout which will improve safety for motorists, cyclists and pedestrians supporting a safer community environment and enhancing road safety for all road users.

Scope of work

The upgrade will include

  • Associated roadworks and line marking
  • Minor footpath, verge and kerb adjustments to accomodate new design geometry
  • Signage and pavement marking improvements
  • Installation of crash barrier on southeast corner of roundabout
