FAQs

• Mainly to address the number of crashes at the intersection, particularly those associated with the right turn from Stone Street
• To provide safer gaps in traffic for vehicles to turn into and out of Stone Street and Frinton Street
• To provide improved pedestrian crossings on all four approaches of the intersection
• To address the concerns raised by the community to date
• It is the most feasible treatment to address crashes and traffic concerns at the intersection given the current constraints. 

Based on the latest video survey conducted by the City, there appears to be non-compliances at the intersection where vehicles are undertaking non-permitted movements, even though the configuration currently does not allow. 

These include, vehicles driving through the intersection between Stone Street and Frinton Street, and vehicles turning right from and to Frinton Street. Once signals are installed, these types of movements will be legal and safely supported.  

The configuration of the intersection and the lack of land availability to accommodate turning pockets, it is unlikely that the new signals will attract rat running. 

The turning movements on Garratt Road will share lanes with through traffic and given less green time than the through movement. These turns will not be able to "filter" through gaps from the opposite movement (with a red arrow visible), meaning that they will be waiting for a decent time to undertake their manoeuver. 

Similarly, for left turns on Garratt Road, they will be held up by any pedestrians crossing Stone Street/Frinton Street if the demand for pedestrians is activated. 

Turning vehicles from side roads are also given minimum green time to undertake their manoeuvers, therefore providing little opportunities to encourage any rat running. 

This closure was conditioned by Main Roads as part of the project upon approving the signals facility at Garratt Road and Stone Street. The closure will be undertaken and funded by Main Roads.

If travelling along Guildford Road and wanting to turn right into Milne Street, then:

• Heading eastbound away from the City, turn right onto Garratt Road, make a left turn into Williamson Street then left or right into Milne Street
• Heading westbound towards the City, make a right turn into Crowther Street, another right turn into Almondbury Street, then left or right into Milne Street. A right turn can also be performed at any other side road currently open before or after Milne Street

If travelling along Milne Street and wanting to turn right into Guildford Road, then:

• Heading eastbound away from the City, continue down Milne Street, make a right at Frinton Street, then do a right turn at the new signals, followed by a right turn at the Guildford Road signals
• Heading westbound towards from the City, utilise Garratt Road to make a right turn into Guildford Road

This was recommended by Main Roads at the early stages of the project to make the new proposed signals the main access to the precincts on either side of Garratt Road. This closure, however, along with the right turn closure from Milne Street, will prevent any rat running currently occurring to avoid the signals at the Guildford Road signals. 

A right turn into and out of Williamson Street will be replaced by a right turn at the new proposed signals. 

For the Maylands Peninsula precinct west of Garratt Road, the City will be installing traffic calming devices as part of the Low-Cost urban Road Safety (LCURS) program, funded by Main Roads. These treatments will be delivered in 2026.

Whilst no treatments are currently proposed within the precinct west of Garratt Road, these can be considered as part of this project. The City will be monitoring the intersection operation and if any rat running is identified, then traffic calming devices will be installed, subject to Main Roads approval.

The City have liaised with the Public Transport Authority in regards to the impact to the 41 bus service, who advised they would align this service through the intersection from Stone Street to Frinton Street. This will result in the relocation of two bus stops along Williamson Street and Crowther Street.
