FAQ's
Due to an increase in urban development in the urban growth corridor, duplication is needed to support the increase in traffic. This duplication will link to previously duplicated segments to the east and west.
For several reasons, the Gnangara Road duplication is a major project staged over three financial years. Factors such as grant funding, service relocations and construction resources mean it is not feasible for the City to complete the project in one financial year.
A full closure is needed to keep road users, pedestrians and workers safe during major construction works.
The work involves deep excavation, rebuilding the road, installing drainage, and using heavy machinery and trucks, which makes it unsafe to allow traffic through the area and impractical to open and close the road frequently.
Losino Boulevard is also a busy road, with about 2,740 vehicles each weekday, including heavy trucks. Keeping it open during these works would create serious safety risks.
Access has been maintained as long as possible:
- June–Dec 2025: Fully open
- Jan–July 2026: Left-in/left-out access only
- July–Oct 2026: Full closure.
The full closure is now required because the intersection itself needs to be completely rebuilt.
The City looked at options to keep the road open, including shorter closures and staged works.
However, these options were not suitable because they would/p>
- Increase safety risks for workers and road users
- Take longer to complete
- Cost more due to extra traffic management
- Increase the risk of damage and rework
- Reduce the overall quality of the finished road.
A single closure is the safest, fastest and most efficient way to complete the work.
If work progresses smoothly, the intersection may reopen earlier, with final finishing works completed under partial lane closures.
Delaying the closure would disrupt the overall timeline, extend construction in the area, and could affect funding, contracts, and planned completion dates.
Alternative routes in and out of Henley Brook and Morgan Fields will remain available and are shown in the project plans.
Traffic on nearby roads is expected to increase during the closure, but the City has reviewed the network and believes it can manage the additional vehicles. Local roads in urban areas are generally designed to handle this level of traffic.
The City will monitor conditions during construction and adjust if needed.
The City used several methods to inform the community, including:
- Sending around 600 letters to residents and property owners
- Advertising in the local newspaper
- Displaying public notices at City buildings and libraries
- Sharing information on the City’s website and social media
- Notifying key stakeholders and emergency services
Information was also shared informally through local community networks and word of mouth.
The City understands the temporary closure will be inconvenient and has worked to minimise impacts where possible.
Access has been maintained throughout most of the project:
- Gnangara Road has remained open
- The intersection stayed fully open until December 2025
- Left-in/left-out access has been provided since January 2026
The full closure is only being introduced now because the intersection must be rebuilt and it’s no longer possible to keep it open safely.
The closure is necessary to complete the works and deliver long-term benefits from the project.
