Scarborough Beach Road and Green Street Roundabout

Main Roads WA are planning to build a new dual-lane roundabout at the intersection of Scarborough Beach Road and Green Street, improving safety and traffic flow for all road users.

Service relocations are scheduled to start in mid-2024, with roundabout construction expected to get underway in the final quarter of the year.

This project is funded by the State Government, following a 2017 election commitment.

Scope

Following a complex program of service relocations, the current two-stage road crossing will be replaced with a new dual-lane roundabout. A new shared path has also been included in the design, improving connectivity for the high number of riders and walkers who are travelling to and from the Glendalough train station and local business hubs.

For safety reasons, the existing one-way access into Birrell Street must be closed to accommodate the new roundabout. Birrell Street will be converted to a cul-de-sac at its junction with Scarborough Beach Road.

Background

Between 2019 and 2023, there were 66 reported crashes at this location.

Most of these crashes occurred during right-turns (more than 80 per cent) or as a result of rear-end collisions. Just under a quarter of these crashes resulted in someone requiring hospitalisation or medical treatment, while more than three-quarters resulted in property damage.
