TBMs to create tunnelling Legacy

Legacy Way is a 4.6 km road tunnel that will connect the Western Freeway at Toowong with the Inner City Bypass at Kelvin Grove.

Annabell will excavate the westbound tunnel. The second tunnel boring machine (TBM), Joyce, which is being assembled on site, will start excavation of the eastbound tunnel in approximately three months.

It will take approximately 18 months for the TBMs to complete the journey from the western worksite at Toowong to the eastern worksite at Kelvin Grove.

The TBMs will operate 24 hours a day, seven days a week.

The rock and dirt excavated by the TBMs will be transported via an underground conveyor to the Mt Coot-tha Quarry.

Once open in 2015, Legacy Way will almost halve peak hour travel times between the Centenary Bridge and the Inner City Bypass.
