What's happening
Early works are underway
Preliminary works have started across the project area, which are an important step in helping inform the design. During these works, intermittent verge closures and stop/slow arrangements will be required on various roads within the project area. These short-term impacts will be implemented during off-peak times (generally, 9:30am to 3pm, Monday to Friday) and will help increase safety for our workforce and the community.
What’s included?
- Geotechnical investigations – testing ground conditions.
- Potholing for service locating – identifying underground utilities.
- Environmental investigations - surveys.
What to expect?
You may see some of our work crews and vehicles accessing the road reserve at various locations along the alignment, Monday to Friday.
Short-term traffic management arrangements will be implemented as required to help increase safety for our workforce and the community.
Out of Hours works
To help support early investigation works, including pavement dipping and Cone Penetration Testing (CPT) within existing traffic lanes, works are scheduled from Monday 9 June to Friday 13 June 2025, between 7pm and 5am.
To facilitate these works, there will be intermittent and rolling lane closures on Tonkin Highway, between Rowley Road and Thomas Road (southbound) and Thomas Road, between Kargotich Road and Wungong South Road.
These works are required to be completed at night to minimise disruption to road users and are subject to change.
Speed limit reduction
To safely build access to our future site office, the speed limit will be reduced to 60 km/h on Mundijong Road between Kargotich Road and Adonis Street from 16 June 2025.
These works are subject to change.
