Preliminary works
Before we start our main works on Queen Street, we will commence work to relocate underground pipes and cables (known as services diversions) ahead of tunnelling at the Mayoral Drive/Queen Street intersection and the Wellesley Street/Queen Street intersection.
These works are estimated to start later this year and take approximately 12 weeks to complete. We will provide further details about these works closer to the start date.
Main works
Once we finish our preliminary works, we will immediately commence our main works package on Queen Street.
The main works will be broken into stages as follows:
Queen Street wastewater diversion September 2024 to December 2025
- Construction of three deep shafts, on Queen Street near Mayoral Drive, on Wellesley Street
East between Queen Street and Lorne Street and on Victoria Street between Queen Street and High Street.
- A 1.35m diameter tunnel boring machine will be used to construct the new 600m long wastewater pipe under Queen Street connecting into the shaft locations (as shown on the map below).
- Three short open-cut trenches at the Queen Street/Wellesley Street intersection to connect existing wastewater networks to our new tunnel.
Mayoral Drive wastewater diversion November 2025 to December 2026
Like Queen Street, a tunnel boring machine will be used to drill beneath Mayoral Drive from Vincent Street under Greys Avenue, and into the carpark near Myers Park.
Closer to the start date we will provide more details regarding the construction methodology and traffic management that will be adopted to keep the community safe.
Marmion Street wastewater diversion November 2025 to December 2026
Like the other stages, a tunnel boring machine will be used to drill beneath Mayoral Drive and Queen Street from Marmion Street and then under Marmion Street down to White Street. There will be some short sections of open-cut trenching along White Street and a small section from Marmion Street across to the other side of Queen Street to pick up some other networks and bring these flows into our new network.
Closer to the start date we will provide more details regarding the construction methodology and traffic management that will be adopted to keep the community safe.
